Hello, citizens of Codeforces!
I want to know your opinion about the absent penalty for WA in the first test.
I think we should have a penalty for ANY failed attempt and first one isn’t exception. I don’t see any difference between failed solutions with WA or WA[X]. What’s more first test as I know is always same with first pretest which is given in the task. If participant is too lazy to check his solution on tests given in the task or he’s absolutely sure about his solution then he must be responsible for failed submissions. So introduction of penalty will teach participants to check his code or writing it more carefully. You can vote here or reply in the comments.
