- C++ Data Structures Write a program to implement two stacks using linked lists. User will push values on first stack, when anelement is popped from first stack it should automatically push to second stack. From second stack user willpop this element explicitlyC# Reverse the stack - This procedure will reverse the order of items in the stack. This one may NOT break the rules of the stack. HINTS: Make use of more stacks. Arrays passed as parameters are NOT copies. Remember, this is a procedure, not a function. private int [] stack; private int size; public void ReverseStack(){ }For the following problems, you need to submit a python code that performs the required functions. Q1: (Stack & Queue) 1. Write a program that utilizes the LinkedStack class and LinkedQueue class to perform the following function. Input :empty stack and a Queue Required: reverse the order of the queue. // you must use the methods of the stack and queue class // Q2) Write a member functions to the class ( CircularQueue ) that performs the followings: 1. Sum-even(CQ) : Print the sum of all even numbers stored in CircularQueue. 2. Perform the followings: a. Create two circular linked lists ( CQ1, CQ2). b. Merge the two circular linked lists in one →CQ1. //Remember: you need to use the class ( CircularQueue ) methods.//
