What is the time complexity of enqueueing an element in a queue?
Step 1: Understand what enqueueing means. Enqueueing is the process of adding an element to the end of a queue.
Step 2: Know that a queue is a data structure that follows the First In First Out (FIFO) principle.
Step 3: Realize that when you add an element to the end of the queue, you do not need to look at or move other elements.
Step 4: Recognize that adding an element at the end of the queue takes the same amount of time, regardless of how many elements are already in the queue.
Step 5: Conclude that since the time taken to enqueue an element does not change with the number of elements, it is considered constant time.
Step 6: Therefore, the time complexity of enqueueing an element in a queue is O(1).
