Q1. Implement LRU cache

Ans.

LRU cache is a data structure that stores the most recently used items, discarding the least recently used items when full.

  • Use a doubly linked list to keep track of the order of items based on their usage.

  • Use a hashmap to quickly access items in the cache.

  • When an item is accessed, move it to the front of the linked list to mark it as the most recently used.
