Hey, Codeforces! Today we have the following situation: if your solution doesn't pass 1st test, you won't get penalty. It's logical because 1st test is always given in statement. But some problems have more than 1 sample, there can be 2 or even 3 tests given. However if your solution passes 1st test and breakes on 2nd (which is sample) you will also get penalty. I think it's wrong and requires a fix.
