  • Q1. Use of Hash Table
  • Ans. 

    Hash tables are data structures that store key-value pairs for efficient retrieval.

    • Hash tables use a hash function to map keys to indexes in an array.

    • They have constant time complexity for insertion, deletion, and lookup operations.

    • Collisions can occur when multiple keys hash to the same index, which can be resolved using techniques like chaining or open addressing.
