You are tasked with implementing a data structure that can insert, delete, and retrieve an element in constant time. Which data structure would you choose to implement this?

  • Binary Search Tree
  • Hash Table
  • Linked List
  • Stack
To achieve constant-time insertion, deletion, and retrieval, a hash table is the most suitable data structure. Hash tables use a hash function to map keys to array indices, providing constant-time access.
