Must be in C++ programming The main objective of this experiment is to gain experience in implementing Data Structures of Stacks and Queues. Task 1: Implement a stack using a singly linked list L. The operations PUSH and POP should still take O(1) time. Task 2: Implement a queue by a singly linked list L. The operations ENQUEUE and DEQUEUE should still take O(1) time. Task 3: Rewrite ENQUEUE and DEQUEUE from Task 2 to detect the underflow and overflow of the queue. Task 4: Implement a stack using two queues and analyze the running times of stack operations. Output Instructions: The output includes a user interface where the user indicates the number of elements to en/dequeue and/or push/pop..
