给定程序中，函数fun的功能是：将N×N矩阵中元素的值按列右移1个位置，右边被移出矩阵的元素绕回左边。例如，N=3，有下列矩阵

1 2 3

4 5 6

7 8 9

计算结果为

3 1 2

6 4 5

9 7 8

请在程序的下划线处填入正确的内容并把下划线删除，使程序得出正确的结果。

注意：源程序存放在考生文件夹下的BLANK1.C中。

不得增行或删行，也不得更改程序的结构！

-A given program, function fun feature is: N × N matrix element values ​ ​ in the column right one position, the right to be out of the elements of the matrix around the back left. For example, N = 3, the following matrix of 123,456,789 results for the 312,645,978 please fill in the application of an underscore at the content and to underscore the right to delete, make the program reach the right result. Note: The source code is stored in a folder under the BLANK1.C candidates in. Delete line by line or not, and shall not change the structure of the program!
