Hash functions and strategies that are used to implement them

The hash function is used to convert keys into indexes of an array. The hash function should, in theory, map every potential key to a distinct slot index, but in reality, this is challenging to do.

A hash function that takes a set of items as input and maps each one to a distinct slot is called a perfect hash function. It is feasible to create a perfect hash function if we know the items and the collection won’t change. Unfortunately, there is no methodical way to build a perfect hash function given a random set of elements. Thankfully, we can still gain performance efficiency, even if the hash algorithm is not perfect.

The size of the hash table can be increased in order to include all possible values for the element range, which is one technique to ensure that the hash function is always perfect. This ensures that every component will have a unique slot. Although this is doable for small numbers of items,...
