3. Use the following linked list and node pointers p1, p2, p3, and p4. Draw a similar diagram to show how this configuration changes when the given program segment is executed or explain why an error occurred. Show the changes in pointer location and the change in data as necessary. (All pointers are movable and the data inside the box are changeable) Given the declaration: struct Node { int data; \}; Node next: i) p2=p1> next > next; (make changes in the diagram given below) ii) p2> next > data =p4> data; (make changes in the diagram given below) iii) p1>data=p4> data; (make changes in the diagram given below) iii) p1> data =p4> data; (make changes in the diagram given below) iv) p1> data =p2> data- > next; (make changes in the diagram given below)
