I got a WA again.

It ran for a little bit more than 5 seconds, and the answer is WRONG!

My code is two posts up, what's wrong with it????

I only changed that to cycle(0).

I don't understand how long do I read input.

I apologise if the question has already been asked, but I simply don't understand it. Here is my code, if it helps:

#include <stdio.h>

int cycle (int n) {
int i=0;
while (n>0) {
i++;
if (n==1) break;
if (n%2 == 1) n=3*n +1;
else n=n/2;
}
return ...
