Queue in C is a versatile and data structure in C which overcomes the problems of insertion and deletion of elements whether from the front end or rear end. Moreover, it has the capability of determining the operations in a way that they can be enqueued and dequeued in any way. Unlike s...
Insertion in a queue is the process of adding an element to the rear end of the queue. The process of insertion can be done using various methods, including: Enqueue: The enqueue operation adds an element to the rear end of the queue. In this operation, the element is added to the end...

Enqueue Operation / Insertion: First check if the queue is full or not. For the first element, set the FRONT pointer to 0. Increment the REAR index by 1. Add the new element in the position which was pointed by REAR. Dequeue Operation / Remove: ...
In Java, the Queue interface is under java.util package. The queue extends the collection interface. It is used to hold an element in a collection which are to be processed and can also perform operations like insertion, deletion etc. In this interface elements are inserted at the end of ...
Thepriority queueis acontainer adaptorthat provides constant time lookup of the largest (by default) element, at the expense of logarithmic insertion and extraction. A user-providedComparecan be supplied to change the ordering, e.g. usingstd::greater<T>would cause the smallest element to appear...
Theelementandpeekmethods return, but do not remove, the head of the queue. They differ from one another in precisely the same fashion asremoveandpoll: If the queue is empty,elementthrowsNoSuchElementException, whilepeekreturnsnull. Queueimplementations generally do not allow insertion ofnullelements...
A Queue implementation that extends this class must minimally define a method Queue.offer(E) which does not permit insertion of null elements, along with methods Queue.peek(), Queue.poll(), Collection.size(), and Collection.iterator(). Typically, additional methods will be overridden as well....
