Found A BUG
By VIIIIIIVX, history, 8 years ago, In English

Hi. My submission for 734D - Антон и шахматы got WA in test 19 in the contest. My submission in contest: 22243153 But today when I submit again that code it got AC. 22283030 What happend? Can you help me??

I just want to know what is between two code. Difference is just //. =/

UPD: Finally I found where is my mistake. I make an array in int main() function and It has some values from the beginning and I did not check them.

:/

Thank you very much. =D

Your l contains garbage value. Declare it outside. Different invocations make l different garbage values sometimes having 'B' 'R' 'Q' etc.. hence if there is no point in that axis it will take that garbage value and test the condition.

the revisions of these two problems are different. I don't know what it means, but it's only explanation

    What do you mean? The above two submissions are exactly the same except for a comment. There is undefined behavior in code due to local defined arrays which contains garbage value being tested in the end.
