Add/Remove & Search in a Hash Table (Implementation)

Insertion in the Table

In this lesson, we will implement the main functionalities and see if it runs on the main driver perfectly. Starting with the insertion operation. The code below shows how insertion works in a HashTable. First of all, we will check if the key is already present in the table. If yes, it will insert the value into the head and point the head to next node. In order to avoid a collision, we will make sure that the array doesn’t get loaded up to a certain threshold. Whenever it crosses the threshold, we shift the elements from current table to an even bigger table.
