Stack and Queue

The video tutorial covers the fundamental concepts of stack and queue data structures. It explains the principles of Last In First Out (LIFO) for stacks and First In First Out (FIFO) for queues. The tutorial also discusses the operations associated with each data structure, such as push, pop, and peek for stacks, and enqueue, dequeue, and peek for queues. Additionally, it explores the complexity and implementation of these structures using arrays and linked lists, highlighting the advantages and challenges of each approach.

Explain the concept of LIFO and how it applies to stack operations.

What is the significance of the peak operation in both stack and queue?

Discuss the time complexity of the push, pop, and peak operations in a stack.

What are the advantages of using linked lists for implementing queues?
