Solution: Design HashSet

Explore how to build a custom HashSet class without built-in libraries by implementing add, remove, and contains methods. Understand the use of a hash function for key distribution and separate chaining with binary search trees to handle collisions. This lesson helps you grasp efficient data structure design techniques necessary for scalable coding solutions.

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 ...
