What is Deque? | Stack and Queue implementation using deque in python | Code Explanation
In this video, we learn how to implement Stack and Queue in Python using the powerful deque (double-ended queue) data structure from the collections module.
What you’ll learn:
Basics of stack (LIFO) and queue (FIFO)
Why deque is better than lists for stack/queue operations
Implementing stack with append() and pop()
Implementing queue with append() and popleft()
Time complexity of stack and queue operations using deque
Why deque?
Python’s deque provides O(1) time complexity for appending and popping from both ends, making it the perfect choice for implementing stacks and queues efficiently.
