Which of the following information is stored in a doubly-linked list’s nodes? Let us define our class template for the Queue implementation.įront and rear instance variable are the linked list node that holds the data and a reference to the next node. once we remove the tail then there is no way to point to the element that was before a tail in a singly linked list unless we have an extra pointer. Removal of an element happens from the front of the Q and if the linked list tail is the front of a queue then how we going to remove the front element of a Q(the tail of linked list) as the linked list does not allow to remove the tail of it at a constant time O(1). The front of Q is the head and rear of the Q is tail due to the remove operation. You can visit my previous article for custom implementation of linked list in Java. While using linked list for the queue implementation, EnQueue operation is implemented by inserting element at the end of the list and DeQueue operation is implemented by deleting an element from the beginning of the list.
