 Push_swap is a very simple and highly effective algorithm.You have at your disposal a list of `int` values, two stacks (`a` and `b`) and a set of instructions.

+You will have to write 2 programs:
 
 - **push_swap**, which calculates and displays on the standard output the smallest program using push_swap instruction language that sorts integer arguments received.
 - **checker**, which takes integer arguments and reads instructions on the standard output. Once read, checker executes them and displays `OK` if integers are sorted. Otherwise, it will display `KO`.
