Problem Breakdown

Understanding the Design Hash Set Problem

Let's break down this LeetCode problem and understand what makes it challenging in interview settings.

Problem Statement

Design a HashSet without using any built-in hash table libraries. Implement MyHashSet class: void add(key) Inserts the value key into the HashSet. bool contains(key) Returns whether the value key exists in the HashSet or not. void remove(key) Removes the value key in the HashSet. If key does not exist in the HashSet, do nothing.
