Solution: Design HashSet

Understand how to implement a custom HashSet class in C++ without built-in libraries by using a hash function combined with binary search tree buckets for collision handling. This lesson guides you through designing methods to add, remove, and check keys, while optimizing for time and space complexity.

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 ...
