In this Java tutorial, we are going to discuss the circular queue and its array implementation in java. What is Circular Queue? Circular Queue is a linear data structure in which operations are performed on FIFO ( First In First Out ) basis . Element at last position is connected to front...

The most common queue implementation is using arrays, but it can also be implemented using lists. Python Java C C++ # Circular Queue implementation in PythonclassMyCircularQueue():def__init__(self, k):self.k = k self.queue = [None] * k self.head = self.tail =-1# Insert an element...
All values will be in the range of [0, 1000]. The number of operations will be in the range of [1, 1000]. Please do not use the built-in Queue library. 题解: Use an array to mimic queue. Have start to pointing to start of queue. ...
(This class is roughly equivalent to ArrayList, except that it is optimized for removing elements at the front and back of the list to facilitate use as a queue or deque. The size, isEmpty, get, set, iterator, and listIterator operations run in constant time. The add op...
One of the benefits of the circular queue is that we can make use of the spaces in front of the queue. In a normal queue, once the queue becomes full, we cannot insert the next element even if there is a space in front of the queue. But using the circular queue, we can use the...
It’s also known with alternative names such as a circular queue or ring buffer, but we will refer to it as a circular array throughout this article. The circular array has FIFO (First In, First Out) mechanism for element insertion and removal operations. Usually, the buffer will have a...

Multimedia Player:When we play songs in a multimedia player, the songs are played in a circular manner. Once the last song is played, the first song will be played next. This is done using a circular queue. In general, when certain tasks are repeated in a circular manner, a circular qu...
