Grokking the Coding Interview Patterns in JavaScript

Solution: Design HashSet

Explore how to implement a custom MyHashSet class in JavaScript without built-in libraries. Learn to design a hash function, handle collisions with binary search trees, and efficiently manage add, remove, and contains operations. This lesson guides you through creating an effective hash set data structure suitable for coding interviews.

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 ...
