Implement a Queue on a char [] array. Do not use ::Queue:: class from the STD library for this example. When you hardcode your queue look to make it work. Then update the code to make the queue circular. The user will input a string and the program will return the string with each letter in the string duplicated. Displaying correct Queue implementation. Utilize the conventional/traditional methods as needed. enqueue() / push_back() dequeue() / pop_front() Sample Execution Please input String: happy
