Check prime number. Find the factorial of a number. In the above program, the function Insert inserts an element into the queue. If the rear is equal to n-1, then the queue is full and overflow is displayed. If front is -1, it is incremented by 1. Then rear is incremented by 1 and the element is inserted in index of rear.

A good example of queue is any queue of consumers for a resource where the consumer that came first is served first. Operations associated with queue are: Enqueue: Adds an item to the queue. If the queue is full, then it is said to be an Overflow condition — Time Complexity : O 1 Dequeue: Removes an item from the queue.

The items are popped in the same order in which they are pushed. This article covers the implementation of queue using data structures and modules from Python library. Queue in Python can be implemented by the following ways:. Skip to content. Change Language.
