/**
 * 867. Transpose Matrix
 *
 * Given a matrix A, return the transpose of A.
 * The transpose of a matrix is the matrix flipped over it's main diagonal, switching the row and column indices of the matrix.
 *
 * Example 1:
 *
 * Input: [[1,2,3],[4,5,6],[7,8,9]]
 * Output: [[1,4,7],[2,5,8],[3,6,9]]
 * Example 2:
 *
 * Input: [[1,2,3],[4,5,6]]
 * Output: [[1,4],[2,5],[3,6]]
 *
 * Note:
 *
 * 1 <= A.length <= 1000
 * 1 <= A[0].length <= 1000
 * */
