There is O(|black cells|) solution. Let's consider only 8 cells near the edge. There are three(four) cases: 1) There are black cells in both side. In this case, already result is fixed because the players can not change a parity of the number of turns while the game ends. 2) ...
(Due to having too many submissions in the early part of the contest, we relaxed this requirement from the earlier one of needing to place in the top 5000 of the round) The contest will be 3 hours. As usual, you may not discuss solution ideas or code until after the contest hours is...

How do you approach upsolving? What helped you the most in getting better at problem-solving over time?
Still i am not able to solve in div2 a,b ,, div3 a,b and div4 c,d. Also, when I solve a problem like 900-1000 rated, I have to also struggle it and too much time need for approaching the problem solution, even don't came the idea. ...
