Hashing uses functions or algorithms to map object data into a representative integer value. A hash table in C (associative array) is a data structure that maps keys to values. It uses a hash function to compute the index for the key. Based on the hash table index, we can store the value at the appropriate location.

Interpolation search is an improved variant of binary search. This search algorithm works on the probing position of the required value. For this algorithm to work properly, the data collection must be in sorted and equally distributed form.
