Hello guys... I need help on this problem. I've tried my code against various outputs, but still the judge shows "Wrong Answer". Where's the problem? At first I thought maybe the numbers(suppose n) which can be expressed as m!(m is another number smaller than n), but not as sum of factorials, are giving me WA; but I tried that way too and got WA. It'd be a great help to me if anyone could point out what should be done. Thanks in advance.
