For this article, we'll implement because it is easier to understand and works reliably under high load.

A method to handle cases where two different keys generate the same array index. This implementation uses Chaining (linked lists at each array index) to resolve collisions.
A mechanism to handle situations where two different keys produce the same hash index. Because the array size is finite and the number of possible keys is infinite, collisions are inevitable. 2. Choosing a Collision Resolution Strategy
