I was creating a problem and faced with one problem. The task is:
given n, print a, b, c, d > 1 such as a*b*c*d = n. In some cases, there are a lot of choices, how to consider all of them? For example, if n = 80, and my code prints 2*4*5*2, and user prints 10*2*2*2, my code with ncmp checker gives WA. How to fix it?
