Q1. Working of LRU cache
Ans. 
LRU cache is a data structure that stores the most recently used items and discards the least recently used items.
• LRU stands for Least Recently Used

• It has a fixed size and when it reaches its limit, the least recently used item is removed to make space for a new item

• It uses a doubly linked list and a hash map to achieve O(1) time complexity for both insertion and deletion

• Example: A web browser caching the most recently
