反转对角搜索

如何解决反转对角搜索

我从 Java 开始，我想知道如何反转图片中显示的对角线搜索，但从左下到右或从右上到左下。

图中对角搜索的代码为：

// top-left to bottom-right - green diagonals

for (int rowStart = 0; rowStart < rowMax - 4; rowStart++) {
  int count = 0;
  int row,col;
  for (row = rowStart,col = 0; row < rowMax && col < colMax; row++,coL++) {
    if (gridTable[row][col] == player) {
      count++;
      if (count >= 4) return 1;
    } else {
      count = 0;
    }
  }
}

// top-left to bottom-right - red diagonals

for (colStart = 1; colStart < colMax - 4; colStart++) {
  count = 0;
  int row,col;
  for (row = 0,col = colStart; row < rowMax && col < colMax; row++,coL++) {
    if (gridTable[row][col] == player) {
      count++;
      if (count >= 4) return 1;
    } else {
      count = 0;
    }
  }
}
