Solution: Design HashSet

Explore how to design a custom MyHashSet class that efficiently stores and manages keys using a hash function and separate chaining with binary search trees. Understand methods to add, remove, and check keys, along with the underlying hash function mechanism and collision resolution to ensure balanced data distribution.

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

  • At most, 10410^4 ...
