back to board Have anybody crash on 3 test?
It's interesting, that my friend decided this problem and on tests with n>50 we have the same answer. I had. You must add in your programm something like this:
if(sum/9>2*n){
printf("0");
return 0;
} thanks. I just found my forgotten! my program cannot print 0 'zero' ( - -") Why is this condition required? The recursive formula takes care of this.. Without this condition my code gets WA3.. And when I add it, it gets AC.. Could you plz give a test case where this condition is really required, where the DP formula fails..?? I don't think it's DP formula's fault
Perhaps when you are deleting leading zero, you haven't judge if the point is >= 0 |
