Linked List implementation of Queue Due to the drawbacks discussed in the previous section of this tutorial, the array implementation can not be used for the large scale applications where the queues are implemented. One of the alternative of array implementation is linked list implementation of queue. The storage requirement of linked representation of a queue with n elements is o(n) while the time requirement for operations is o(1). In a linked queue, each node of the queue consists of two parts i.e. data part and the link part. Each element of the queue points to its immediate next element in the memory. In the linked queue, there are two pointers maintained in the memory i.e. front pointer and rear pointer. The front pointer contains the address of the starting element of the queue while the rear pointer contains the address of the last element of the queue. Insertion and deletions are performed at rear and front end respectively. If front and rear both are NULL, it ind...
