4 Write a C++ Program to delete a node at the beginning and at the end of the linked List? (10 Points) 5) Write a C++ Program to create a node at the beginning and at the end of a linked list? (10 Points)? 6) Write a C++program to display middle element of a linked list in one pass? (10 Points)? Hint: Create two pointers slow and fast. pointer one node at a time. Move the fast pointer two nodes at a time &slow Check when the link part of the fast pointer becomes NULL (odd number of nodes) or the fast pointer becomes NULL (even mumber of nodes), at that point slow pointer points to the middle clement
