Separate Chaining

Separate chaining

In separate chaining, the process involves building a linked list of key–value pairs for each search array index. The collided items are chained together through a single linked list, which can be traversed during lookup of a specific key. Collision resolution through chaining with linked lists is a common method of implementation of hash tables. Let ${\displaystyle T}$ be the hash table, ${\displaystyle x}$ be an element ${\displaystyle (k,v)}$, and ${\displaystyle k}$ be its key. The operations involved are as follows:
