Implement queue using linked list
Queue is useful data structure which are used to solve most of standard problems. In this post are described how to implement queue in singly linked list which support queue operation. Such as insertion deletion and its size calculation.
Queue Operation
Queue follow FIFO (first in first out) properties which are implemented by using of enqueue and dequeue function. Here given list of functionality which is generally used in queue.
enqueue : Inserting a new node at the end of queue.
dequeue : Delete a new element from the beginning of queue.
size : Returns the number of node exists in queue.
isEmpty : Check that, given queue is empty or not.
peek : Returns the front node value of queue.
Time complexity of all above operation is O(1). Linked list is suitable to implementation of those operation. Here given code implementation process.
