Questions & Step-by-Step Solutions
What is the time complexity of removing 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, meaning the first element added is the first one to be removed.
Step 2: Identify the operation of removing an element from a queue. This operation is typically called 'dequeue'.
Step 3: Recognize that when you remove an element from the queue, you are removing the front element.
Step 4: Note that removing the front element does not depend on the number of elements in the queue. It is a direct operation.
Step 5: Conclude that since the operation takes a constant amount of time, the time complexity for removing an element from a queue is O(1).
