First we understand what is hash function. A hash function is mostly used in Hashmaps. It maps different keys to a set of values. There may occur a case when we have same key but different values. This case is called collision. So we have to use different collision handling techniques that are open addressing and separate chaining.
A perfect hash function maps key-value pair such that there are no collisions.
