Examples
matrix = [[1,2,3,4],[5,1,2,3],[9,5,1,2]]trueIn the above grid, the diagonals are: "[9]", "[5, 5]", "[1, 1, 1]", "[2, 2, 2]", "[3, 3]", "[4]". In each diagonal all elements are the same, so the answer is True.
matrix = [[1,2],[2,2]]falseThe diagonal "[1, 2]" has different elements.
Constraints
m == matrix.lengthn == matrix[i].length1 <= m, n <= 200 <= matrix[i][j] <= 99Follow up:What if the matrix is stored on disk, and the memory is limited such that you can only load at most one row of the matrix into the memory at once?What if the matrix is so large that you can only load up a partial row into the memory at once?How Interview Coder Helps with Leetcode Problems
