1/**
2 * [867] Transpose Matrix
3 *
4 * Given a 2D integer array matrix, return the transpose of matrix.
5 * The transpose of a matrix is the matrix flipped over its main diagonal, switching the matrix's row and column indices.

8 * Example 1:
9 * 
10 * Input: matrix = [[1,2,3],[4,5,6],[7,8,9]]
11 * Output: [[1,4,7],[2,5,8],[3,6,9]]
12 * 
13 * Example 2:
14 * 
15 * Input: matrix = [[1,2,3],[4,5,6]]
16 * Output: [[1,4],[2,5],[3,6]]
17 * 
18 *  
19 * Constraints:
20 * 
21 * 	m == matrix.length
22 * 	n == matrix[i].length
23 * 	1 <= m, n <= 1000
24 * 	1 <= m * n <= 10^5
25 * 	-10^9 <= matrix[i][j] <= 10^9
