How many chessboards can be found in the painting? I was wondering.

EXPLANATION CODE:
1) This code reads a sequence of Painting objects from standard input, which contain the row, column, and color (either 0 or 1, representing black and white, respectively) of a square in a checkerboard. For each Painting, the code outputs the number of rectangles of size 8x8 that can be created on the checkerboard, using the top-left square of the rectangle as the square indicated by the Painting object, while ensuring that the top-left square is not a white square (if it were, the rectangle would not be aligned with the checkerboard's grid).
2) The code defines a Painting struct with three fields: row (an integer indicating the row of the square), col (an integer indicating the column of the square), and isWhite (an integer indicating whether the square is white, with 0 indicating black and 1 indicating white).
3) The main function begins by ignoring any input up to the end of the current line. It then enters a loop that reads Painting objects from std::cin until there is no more input, and for each object, it outputs the number of 8x8 rectangles that can be created on the checkerboard with the top-left square being the square indicated by the Painting object, as described above. The output is separated by newline characters.
