Answer / Anjali Singh
"Stack: A linear data structure that follows Last-In-First-Out (LIFO) principle. Elements are inserted at one end, called the top, and removed from the opposite end. Stacks have constant-time O(1) average complexity for push(), pop() and peek() operations.nnQueue: A linear data structure that follows First-In-First-Out (FIFO) principle. Elements are inserted at one end, called the rear, and removed from the opposite end, called the front. Queues have O(1) average complexity for enqueue() operation and O(n) for dequeue()."n
