Hi. My submission for 734D - Anton and Chess 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
