Solution: Design HashSet

Explore the design and implementation of a custom HashSet in C#. Understand key concepts including hash functions, collision handling with separate chaining, and the use of binary search trees in bucket storage. This lesson guides you through building a MyHashSet class to insert, remove, and check keys with efficient time and space complexity.

We'll cover the following...

Statement

Design a MyHashSet class without using any built-in hash table libraries and implement the following methods in it:

  • void add(key): Inserts the value key into the HashSet.

  • bool contains(key): Returns TRUE if the key exists in the HashSet, FALSE otherwise.

  • void remove(key): Removes the value key if it exists in the HashSet.

Constraints:

  • 00 ≤\leq key ≤106\leq 10^6 ...
