给定程序中，函数fun的功能是：将a所指3×5矩阵中第k列的元素左移到第0列，第k列以后的每列元素依次左移，原来左边的各列依次绕道右边。

例如，有以下矩阵：

1 2 3 4 5

1 2 3 4 5

1 2 3 4 5

若k结果为2，程序执行结果为：

3 4 5 1 2

3 4 5 1 2

3 4 5 1 2

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。

-A given program, function fun feature is: a 3 × 5 matrix referred to in the first k elements of the left column to move Section 0, the k elements of each column after column followed by the left, the original columns in the left turn Bypass on the right. For example, the following matrix: 123,451,234,512,345 If k is 2, the program execution results: 345,123,451,234,512 in the program underscore the right content at the fill and to remove the underscore, so that the program reach the right result.
