Description

Technical Field

[0001] The present application relates to the field of fintech, and in particular, to a method, device, storage medium, and electronic device for recycling electronic vouchers. Background Art

[0002] In the era of the rapid development of Internet finance, with the high-speed development of Internet electronic payment, the use of electronic vouchers has become more and more popular. As the scenarios of using electronic vouchers gradually increase, the growth rate of the demand for electronic vouchers is also getting faster and faster. At the same time, at the end of the transaction using the electronic voucher, due to the large number of issued electronic vouchers, a large number of expired electronic vouchers are generated, resulting in a waste of system resources.

[0003] The current method for recycling expired electronic vouchers is to sort them according to the end date of the electronic vouchers, and the electronic vouchers that expire first are destroyed first, so as to clean up the expired electronic vouchers. When a new transaction is carried out, a new batch of electronic vouchers is recreated to avoid the expired electronic vouchers occupying storage resources. However, due to the large base number of electronic vouchers, the process of cleaning up expired electronic vouchers and creating new electronic vouchers is complex and inefficient, and at the same time, resources are wasted many times in the destruction and creation processes, so that the system resources are not reasonably utilized.

[0026] It should be noted that the method, device, storage medium, and electronic device for recycling electronic vouchers determined in this disclosure can be used in the field of financial technology, and can also be used in any field other than the field of financial technology. The application fields of the method, device, storage medium, and electronic device for recycling electronic vouchers determined in this disclosure are not limited.

[0027] According to an embodiment of the present application, a method for recycling electronic vouchers is provided.

[0028] Figure 1 is a flowchart of the method for recycling electronic vouchers according to an embodiment of the present application. As Figure 1 shown, the method includes the following steps:

[0029] Step S102, obtain the number of vouchers of invalid vouchers, and calculate at least one first power exponent value corresponding to the invalid vouchers according to a preset base value and the number of vouchers.

[0030] Specifically, the vouchers can be electronic vouchers used in transactions, and can exist in the form of two-dimensional codes, digital codes, or electronic bills. Before the transaction starts, the vouchers can include information such as voucher styles and voucher numbers. When the vouchers are used in a certain transaction, transaction information can be added to, for example, the two-dimensional code existing in the vouchers. At this time, the vouchers can be used. After the transaction ends, some unused vouchers are invalid vouchers.

[0031] It should be noted that when recycling and storing invalid vouchers in this application, a buddy algorithm is used to establish an idle electronic voucher hash table. That is, the Key value in the hash table is the exponent of the power, and the Value value is the value obtained by performing a power operation on the preset base and the exponent. Figure 2 is a schematic diagram of an optional hash table provided according to an embodiment of the present application. As Figure 2 shown, the base can be 2, Key1 can be 0, then Value1 is 2 0 , that is, each storage space in the storage chain with Key = 1 can store 1 voucher, Key2 is 1, and Value2 is 2 1 , and so on, KeyN can be N, then ValueN is 2 N, that is, each storage space in the storage chain with Key = N can store 2 N vouchers. Through this method, the number of vouchers in each storage space can be accurately determined by the Key value. Since each storage space can only have two storage states: empty or full, the storage capacity of each storage space can be accurately determined, so that the storage space of invalid vouchers can be quickly allocated, recycled, and quickly obtained when reused.

[0032] After obtaining the invalid vouchers, it is necessary to first determine the number of invalid vouchers and determine the power exponent value according to this number and the preset base number. Since the number of invalid vouchers to be recycled is large, it is necessary to reasonably allocate the storage space of the invalid vouchers. Therefore, it is necessary to determine the Key value corresponding to the storage location according to the base number and the number of invalid vouchers in order to accurately store the invalid vouchers. For example, there are 32 invalid vouchers. When the base number is 2, since 2 5 = 32, 32 invalid vouchers can be directly stored in the storage space in the linked list corresponding to Key = 5.

[0033] Since the number of invalid vouchers is random and may be too large, it is necessary to reasonably allocate the storage space corresponding to the invalid vouchers. Optionally, in the method for recycling electronic vouchers provided in the embodiments of the present application, calculating at least one first power exponent value corresponding to the invalid vouchers according to the preset base number value and the number of vouchers includes: randomly setting at least one initial power exponent value; determining the first initial power corresponding to each initial power exponent value according to the base number value to obtain at least one first initial power, and adding at least one first initial power to obtain a first initial result; determining whether the first initial result is equal to the number of invalid vouchers; in the case where the first initial result is not equal to the number of invalid vouchers, resetting the initial power exponent value and re-executing the steps of determining the first initial power corresponding to each initial power exponent value according to the base number value to obtain at least one first initial power, and adding at least one first initial power to obtain a first initial result until the first initial result is equal to the number of invalid vouchers; in the case where the first initial result is equal to the number of invalid vouchers, determining the initial power exponent value as the first power exponent value to obtain at least one first power exponent value.

[0034] Specifically, after determining the base number and the quantity of invalid vouchers, at least one power exponent value can be randomly determined first. Then, according to the power exponent value and the base number, powers corresponding to each power exponent are generated, and the at least one power is summed to obtain a summation result. This result is compared with the quantity of invalid vouchers. If they are equal, the invalid vouchers can be stored according to the Key value corresponding to the power exponent. If they are not equal, at least one power exponent value needs to be re-determined and recalculated until the summation result is equal to the quantity of invalid vouchers. Thus, the storage space for the invalid vouchers to be stored can be reasonably allocated.

[0035] For example, when the base number is 2 and the quantity of invalid vouchers is 111, the power exponent value can be set to 7. Then calculate 2 7 =128, which is greater than 111. The power exponent value needs to be reset. When the power exponent values are 0, 1, 2, 3, 5, 6, 2 6+ 2 5+ 2 3+ 2 2+ 2 1+ 2 0 =111. Therefore, 0, 1, 2, 3, 5, 6 can be determined as the power exponent values corresponding to this batch of invalid vouchers. Further, according to the Key values corresponding to the power exponent values, that is, Key = 0, 1, 2, 3, 5, 6, the storage space in the linked list with Key = 0, 1, 2, 3, 5, 6 can be obtained for storing the invalid vouchers.

[0036] Step S104: According to the mapping relationship between the first power exponent value and the keywords in the hash table, determine the keywords corresponding to each first power exponent value in the hash table, and obtain the free storage units in the linked list corresponding to the keywords, getting at least one free storage unit. Each keyword in the hash table corresponds to a linked list, and the storage units in the linked list include free storage units and non-free storage units. No data is stored in the free storage units, and all storage spaces in the non-free storage units are stored with data.

[0037] Specifically, there can be a mapping relationship between the first power exponent value and the keyword Key in the hash table. For example, the power exponent value = Key value. Through the mapping relationship between the first power exponent value and the keyword Key in the hash table, the storage space for the invalid vouchers can be allocated according to the power exponent value.

[0038] Step S106: Store the invalid vouchers into at least one free storage unit and clear the storage information in the invalid vouchers. The invalid vouchers include storage information and attribute information.

[0039] Specifically, after the space allocation, the invalid vouchers can be stored, and the storage information related to the transaction in the invalid vouchers can be deleted in the storage space, and only the attribute information is retained, so that the vouchers can be used at the boundary when reused next time.

[0040] The method for recycling electronic vouchers provided by the embodiments of the present application calculates at least one first power exponent value corresponding to the invalid vouchers according to the preset base value and the number of vouchers by obtaining the number of vouchers of the invalid vouchers; determines the keyword corresponding to each first power exponent value in the hash table according to the mapping relationship between the first power exponent value and the keyword in the hash table, and obtains the free storage units in the linked list corresponding to the keyword, so as to obtain at least one free storage unit, wherein each keyword in the hash table corresponds to a linked list, and the storage units in the linked list include free storage units and non-free storage units, no data is stored in the free storage units, and all storage spaces in the non-free storage units are stored with data; stores the invalid vouchers into at least one free storage unit, and clears the storage information in the invalid vouchers, wherein the invalid vouchers include storage information and attribute information. This solves the problems in the related art that the efficiency of recycling invalid vouchers is low and the invalid vouchers cannot be used again. By storing the invalid vouchers in the storage space of the linked list in the hash table and clearing the information in the invalid vouchers after storage, blank vouchers can be directly obtained from the hash table during the next transaction, thus completing the storage and reuse of the invalid vouchers, and further achieving the effects of efficiently processing the invalid vouchers, increasing the utilization rate of the invalid vouchers, and efficiently using the storage units.

[0041] Optionally, in order to accurately store the invalid vouchers, in the method for recycling electronic vouchers provided by the embodiments of the present application, storing the invalid vouchers into at least one free storage unit includes: respectively determining a first target power according to each first power exponent value and the base value to obtain at least one first target power; grouping the invalid vouchers according to the first target power to obtain at least one group of invalid vouchers, wherein the number of invalid vouchers in each group of invalid vouchers is the same as a first target power; storing each group of invalid vouchers into a target free storage unit, where the target free storage unit is the free storage unit corresponding to the first power exponent value of a group of invalid vouchers.

[0042] Specifically, after calculating at least one power exponent value, it is necessary to calculate the power corresponding to each power exponent value according to the base and each power exponent value, group the invalid vouchers according to the size of the power, and store each group of invalid vouchers in the storage space corresponding to the corresponding power exponent value, so as to complete the storage.

[0043] For example, when the base is 2 and the number of invalid vouchers is 111, and when the power exponent values are: 0, 1, 2, 3, 5, 6, 2 6+ 2 5+2 3+ 2 2+ 2 1+ 2 0 = 111, so the power exponent values corresponding to this batch of invalid vouchers can be determined as 0, 1, 2, 3, 5, 6, and the corresponding power calculations are performed, that is: 64, 32, 8, 4, 2, 1. Then, 111 invalid vouchers need to be divided into 6 groups, and the number of vouchers in each group is: 64, 32, 8, 4, 2, 1. And each group of vouchers is stored in the corresponding storage space. For example, 64 invalid vouchers are stored in the free storage space in the linked list corresponding to Key = 6. Since each storage space in the linked list with Key = 6 can only store 64 invalid vouchers, the requirement of complete storage can be met, thus preventing the situation where the storage space is not fully filled. In this embodiment, by determining the storage space corresponding to the invalid vouchers, the effect of reasonably storing the invalid vouchers is achieved.

[0044] Optionally, in the method for recycling electronic vouchers provided in the embodiments of the present application, after storing the invalid vouchers in at least one free storage unit and clearing the storage information in the invalid vouchers, the method further includes: determining whether there are non-free storage units in the initial linked list, where the initial linked list is any one of the multiple linked lists in the hash table; in the case where there are non-free storage units, determining whether the number of non-free storage units is greater than or equal to the base value; in the case where the number of non-free storage units is greater than or equal to the base value, obtaining the second power exponent value corresponding to the initial linked list; incrementing a preset value based on the second power exponent value to obtain an updated power exponent value, and obtaining the linked list corresponding to the updated power exponent value to obtain the target linked list; obtaining non-free storage units with the number of the second power exponent value in the initial linked list to obtain multiple target storage units, and storing the invalid vouchers in the multiple target storage units in the free storage space in the target linked list.

[0045] Specifically, after the storage is completed, it is necessary to check whether there are multiple non-free storage units in the hash table. In the case where there are multiple non-free storage units in a certain linked list in the hash table, it is necessary to determine the number of non-free storage units, and in the case where the number meets the merging requirement, the vouchers in the multiple non-free storage units are merged and stored. Thereby saving the storage space in each linked list and improving the acquisition efficiency when obtaining vouchers at the same time.

[0046] For example, when the base number is 2, there are non-idle storage units in the linked list with Key = 5. At this time, it is necessary to determine whether the number of non-idle storage units is greater than or equal to the base number, that is, whether it is greater than or equal to 2. If it is greater than or equal to 2, it can be determined that two non-idle storage units can be merged. Thus, the vouchers stored in the storage spaces of the two linked lists with Key = 5 can be stored in the storage space of a linked list with Key = 6, so that the occupation of two storage spaces becomes the occupation of one storage space. And when querying, the vouchers can be directly obtained from the storage space with Key = 6 through the value of 64, avoiding the phenomenon that the vouchers cannot be obtained from the storage space with Key = 6 after determining Key = 6.

[0047] Optionally, in the method for recycling electronic vouchers provided in the embodiments of the present application, after storing the invalid vouchers in at least one idle storage unit and clearing the storage information in the invalid vouchers, the method further includes: determining whether there are incompletely stored storage units in the initial linked list, where the incompletely stored storage unit is a storage unit whose storage space is not completely occupied, and the initial linked list is any one of multiple linked lists in the hash table; when there are incompletely stored storage units in the initial linked list, determining the number of invalid vouchers in the incompletely stored storage units to obtain a target number; randomly setting at least one initial power exponent value; determining the second initial power corresponding to each initial power exponent value according to the base number to obtain at least one second initial power, and adding the at least one second initial power to obtain a second initial result; determining whether the second initial result is equal to the target number; when the second initial result is not equal to the target number, resetting the initial power exponent value and re-executing the steps of determining the second initial power corresponding to each initial power exponent value according to the base number to obtain at least one second initial power and adding the at least one second initial power to obtain a second initial result until the second initial result is equal to the target number; when the second initial result is equal to the number of vouchers, determining the initial power exponent value as the second power exponent value to obtain at least one second power exponent value; determining the idle storage unit corresponding to each second power exponent value to obtain at least one idle storage unit, and storing the invalid vouchers in the incompletely stored storage units in the at least one idle storage unit.

[0048] Specifically, after the storage is completed, it is necessary to check whether there are incompletely stored storage units in the hash table. When there are partially stored storage units in a certain linked list in the hash table, the partially stored storage units need to be split, and the split vouchers are stored in the corresponding storage units, so that each storage unit in the hash table is in a completely stored state, and thus the storage amount in each storage unit can be accurately determined.

[0049] For example, in the linked list with Key = 8, there is a storage unit that stores only 145 vouchers. At this time, the 145 vouchers need to be split according to the base number to determine the power exponent value corresponding to the 145 vouchers. When the base number is 2, it can be determined that 2 7+ 2 4+ 2 0 = 145. Therefore, the power exponent values corresponding to the 145 vouchers are 0, 4, and 7. Then, 145 needs to be divided into three parts: 1, 16, and 128, and the three parts of vouchers are synchronously stored in the free storage spaces of the three linked lists with Key = 0, Key = 4, and Key = 7, so that each storage space is in a fully stored state.

[0050] Not only can invalid vouchers be recycled, but vouchers can also be obtained from the hash table for reuse. Optionally, in the method for recycling electronic vouchers provided in the embodiments of the present application, before obtaining the number of invalid vouchers, the method further includes: obtaining the number of invalid vouchers to be issued, and determining a third power exponent value according to the number of invalid vouchers to be issued and the base value; obtaining invalid vouchers from the linked list corresponding to the third power exponent value, adding storage information to the invalid vouchers to obtain target vouchers, and issuing the target vouchers according to the target service; obtaining the remaining target vouchers after the target service is completed, and determining the remaining target vouchers as invalid vouchers.

[0051] Specifically, when obtaining vouchers, they can be obtained from the corresponding storage space according to the voucher requirements. For example, if the number of vouchers to be obtained is 64, they can be obtained from the storage space in the linked list with Key = 6. After obtaining the vouchers, it is also necessary to add the content corresponding to the transaction as storage information to the vouchers according to the transaction requirements, so as to obtain vouchers that can be used for the transaction. After the transaction ends, the remaining vouchers are the invalid vouchers to be recycled.

[0052] Optionally, in the method for recycling electronic vouchers provided in the embodiments of the present application, determining the third power exponent value according to the number of invalid vouchers to be issued and the base value includes: randomly setting a fourth power exponent value according to the base value, and determining a second target power according to the fourth power exponent value and the base value; determining whether the second target power is greater than or equal to the number of invalid vouchers to be issued; in the case where the second target power is less than the number of invalid vouchers to be issued, increasing the fourth power exponent value by a preset value to obtain an updated fourth power exponent value, and re-executing the step of determining the second target power according to the fourth power exponent value and the base value until the second target power is greater than or equal to the number of invalid vouchers to be issued; in the case where the second target power is greater than or equal to the number of invalid vouchers to be issued, determining the fourth power exponent value as the third power exponent value.

[0053] Specifically, when obtaining vouchers, it is also necessary to first determine the power exponent value, determine the power according to the power exponent value and the base number, and obtain the vouchers from the corresponding storage unit according to the determined power.

[0054] For example, when the base number is 2 and the voucher to be obtained is 100, it is necessary to first determine the power exponent value, which can be 7, and then calculate 2 7 = 128 which is greater than 100. So, 100 vouchers can be obtained from the storage unit with Key = 7.

[0055] It should be noted that when there is no non-idle storage unit in the linked list with Key = 7, it is necessary to obtain from a storage unit with a larger storage capacity than the storage unit corresponding to Key = 7, that is, the storage unit in the linked list with Key = 8. After obtaining 100 vouchers from the storage unit in the linked list with Key = 8, the remaining vouchers also need to be allocated to the corresponding storage units, so that each storage unit is either idle or in a fully stored state.
