Linked list question. The answer is highlighted in red. Could you show me step by step how to solve this. Thanks!
In a programming language (Pascal), the declaration of a node in a singly linked list is shown in Figure P6.7(a). The list referred to for the problem is shown in Figure P6.7(b). Given P to be a pointer to a node, the instructions DATA(P) and LINK(P) referring to the DATA and LINK fields, respectively, of node P are equivalently represented by P↑. DATA and P↑.

A stack-ended queue, sometimes known as a steque, is a data type that allows push, pop, and enqueue operations. Make an API for this ADT. Create a linked-list implementation.
Implement a circular queue by writing circular.h and circular.c. Here are the contents of circular.h: #define QUEUE_SIZE 100 typedef struct { int head; int tail; int itemCount; int items[QUEUE_SIZE]; } CircularQueue; void CircularInitialize(CircularQueue * q); void CircularEnqueue (CircularQueue * q, int value); int Circular Dequeue (CircularQueue * q, int *pValue); Using an array, implement a circular queue of up to 100 elements of type integer. Implement the functions CircularEnqueue() and Circular Dequeue () to place numbers in the head of the queue and read them from the tail of the queue tail. A circular queue only saves the last n entries (where n is the number of elements in the queue). Overwrite the oldest entries with newest entries once the queue is full.
Java Algorithm Programming Question Implement the ADT queue by using a circular linked list. Recall that this list has only an external reference to its last note. Example Output: Create a queue: isEmpty () returns true Add to queue to get Joe Jess Jim Jill Jane Jerry isEmpty () returns false Testing getFront and dequeue: Joe is at the front of the queue. Joe is removed from the front of the queue. Jess is at the front of the queue. Jess is removed from the front of the queue. Jim is at the front of the queue. Jim is removed from the front of the queue. Jill is at the front of the queue. Jill is removed from the front of the queue. Jane is at the front of the queue. Jane is removed from the front of the queue. Jerry is at the front of the queue. Jerry is removed from the front of the queue. The queue should be empty: isEmpty() returns true Add to queue to get Joe Jess Jim Testing clear: isEmpty() returns true Add to queue to get Joe Jess Jim Joe is at the front of the queue. Joe is…
