Trie is a tree data structure used for efficient retrieval of key-value pairs.
Trie is also known as prefix tree.
Each node in a trie represents a single character of a key.
Trie is commonly used in autocomplete and spell checking algorithms.

- Q2. LRU Implementation
- Ans.
LRU (Least Recently Used) is a cache eviction policy that removes the least recently used items first.
LRU cache stores key-value pairs with a maximum capacity.
When the cache is full, the least recently used item is removed to make space for new items.
Each time a key is accessed, it is moved to the front of the cache to indicate it was recently used.
