Options:

Correct Answer: O(1)

Solution:

Deleting an element from the front of a queue is done in constant time, hence O(1).

What is the time complexity of deleting an element from a queue?

What is the time complexity of deleting an element from a queue?

Step 1: Understand what a queue is. A queue is a data structure that follows the First In First Out (FIFO) principle.
Step 2: Identify where deletion happens in a queue. Deletion occurs at the front of the queue.
Step 3: Recognize that deleting an element from the front of the queue does not depend on the number of elements in the queue.
Step 4: Realize that this deletion operation takes the same amount of time regardless of how many elements are in the queue.
Step 5: Conclude that since the time taken is constant, we express this as O(1) in Big O notation.
