1. You are required to complete the code of our StackToQueueAdapter class. The class should mimic the behaviour of a Queue and implement FIFO semantic.
2. Here is the list of functions that are written in the class
2.1. add -> Accepts new data if there is space available in the underlying array or
print "Queue overflow" otherwise.
2.2. remove -> Removes and returns value according to FIFO, if available or print
"Queue underflow" otherwise and return -1.
2.3. peek -> Returns value according to FIFO, if available or print "Queue
underflow" otherwise and return -1.
2.4. size -> Returns the number of elements available in the queue.
3. Input and Output is managed for you.Input Format
