Compare the breadth-first and depth-first search algorithms : Queue Data Structure

This video tutorial introduces the queue data structure, explaining its FIFO nature and operations like enqueue and dequeue. It provides real-world examples and demonstrates how to implement a queue in Python using the deque class. The video concludes with a recap and a preview of the next topic, the BFS algorithm.

What is the primary characteristic of a queue data structure?

• Last In, First Out

• First In, First Out

• Random Access

• None of the above

Which operation is used to add an item to a queue?

• Dequeue

• Push

• Pop

• Enqueue

In Python, which method is used to remove an item from the front of a queue implemented using deque?

• pop

• append

• popleft

• remove

What happens to the queue after all elements are removed in the given Python example?

• It becomes empty

• It remains unchanged

• It reverses the order of elements

• It becomes a stack

What topic is introduced as the next subject to be covered after queues?

• Binary Trees

• BFS algorithm

• Sorting algorithms

• DFS algorithm
