Collisions in Hash Tables
Explore how collisions occur in hash tables when mapping keys to array indices and learn three primary strategies to handle these collisions: linear probing, chaining, and resizing the array. Understand the advantages and drawbacks of each method to manage collisions in C# hash tables efficiently.

When you map large keys into a small range of numbers from 0-N, where N is the size of the array, there is a huge possibility that two different keys may return the same index. This phenomenon is called a collision.
Strategies to handle collisions
There are several ways to work around collisions in the array. The three most common strategies are:
- Linear probing
- Chaining
- Resizing the array
1. Linear probing
This strategy suggests that if your hash function returns an index that is already filled, ...
