+ * 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
+ * */
