(函數,數組)編寫一個函數,將一個3*3的二維數組轉置。
提示:轉置就是:
                                      1   2   3
                                      4   5   6
                                      7   8   9

變成這樣:
                                      1   4   7   
                                      2   5   8
                                      3   6   9
