Transpose Matrix · Coding Interview Practice

Transpose MatrixGiven a 2D integer matrix, return its transpose: the matrix flipped over its main diagonal so rows become columns and columns become rows.Constraints

m == matrix.length, n == matrix[i].length

1 <= m, n <= 1000

-10^9 <= matrix[i][j] <= 10^9

Examples

Input: matrix = [[1, 2, 3], [4, 5, 6], [7, 8, 9]] Output: [[1, 4, 7], [2, 5, 8], [3, 6, 9]]

Input: matrix = [[1, 2, 3], [4, 5, 6]] Output: [[1, 4], [2, 5], [3, 6]]
