Add/Remove & Search in Hash Table (Implementation)

In the previous lesson, we built a HashTable class and designed a hash function. Using that code, we will implement the main functionalities of a hash table.

Resizing in a Hash Table

To start things off, we will make sure that the hash table doesn’t get loaded up beyond a certain threshold. Whenever it crosses the threshold, we shift the elements from the current table to a new table with double the capacity. This helps us avoid collisions.

To implement this, we will make the resize() function.
