A Binary Search Tree (BST) stores elements in sorted order, enabling O(log n) average-case search, insertion, and deletion. The key

A Queue is a linear data structure that follows the First-In-First-Out (FIFO) principle, complementary to the Stack. We operate with

A Stack is a linear data structure that follows the Last-In-First-Out (LIFO) principle. It supports two primary operations: push (add

Implementing a LinkedList is a common interview question that tests understanding of pointer-based data structures and dynamic memory management. The

A HashTable (or HashMap) is one of the most frequently asked data structure implementations in coding interviews. It provides O(1)
