I submited a program which just return 0 and print nothing but on some cases in grading it told me OK! how is that ?? I printed nothing to consider it ok :)
z-ram
maybe the sol is 0?xD
I don't print anything just like this int main(){return 0;}
Well the comparators value that equals your value is set to 0 first so it compares 0 = 0 ? and that's true at least I think so...
this should be fixed right ? maybe comparing files is more safe ?
