Description

Given a 2D integer array matrix, return its transpose.

The transpose of a matrix is obtained by reflecting it along its main diagonal, swapping its row and column indices.

Example 1:

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

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

Example 2:

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

Output: [[1,4],[2,5],[3,6]]
