Describe the concept of hashing
WebHashing is a technique to convert a range of key values into a range of indexes of an array. We're going to use modulo operator to get a range of key values. Consider an example of hash table of size 20, and the following items are to be stored. Item are in the (key,value) format. (1,20) (2,70) (42,80) (4,25) (12,44) (14,32) (17,11) (13,78) (37,98) WebNov 2, 2024 · Hashing is the solution that can be used in almost all such situations and performs extremely well compared to above data structures like Array, Linked List, …
