    vovuh was the one who actually added this training for div2. He might be the only person who can fix it now.

Can someone explain this in problem J Grid Coloring

• For each blue square, all squares in the rectangle from the top left of the grid to that square must also be blue.

Does this mean if grid[i][j]=Blue then grid[i-x][j-x] will also be Blue? when x=[i-1,0]
