Problem 44657. Kurosu checker

  • Created by HH
The game of Kurosu is simple. A square grid contains cells that can be filled with either a 'X' or an 'O', similarly to a tic-tac-toe board. Game rules are as follows:
1. The game is played on a 6x6 board.
2. Each row and each column must contain exactly 3 'X's and 3 'O's.
3. Only 2 'X's or 'O's can be placed consecutively, either in a row or in a column.
4. Diagonals are of no importance.
In this problem, given a completely filled Kurosu board, b, return 'true' if the board complies with game rules or 'false' if it does not. 'X's and 'O's are represented by 1s and 0s, respectively.
Example 1:
b = [1 0 1 0 0 1
1 1 0 1 0 0
0 0 1 0 1 1
0 1 0 1 1 0
1 1 0 1 0 0
0 0 1 0 1 1];
tf = true;
Example 2:
b = [1 0 1 0 1 0
1 1 0 1 0 0
0 1 1 0 0 1
0 1 0 1 1 0
1 0 0 1 0 0
0 0 1 0 1 1];
tf = false;
