Magic Squares In Grid Leetcode In depth solution and explanation for leetcode 840. magic squares in grid in python, java, c and more. intuitions, example walk through, and complexity analysis. better than official and forum solutions. We directly enumerate the top left coordinates \ ( (i, j)\) of each \ (3 \times 3\) submatrix, then check whether the submatrix satisfies the "magic square" property. if so, we increment the answer by one. after the enumeration, we return the answer.
