阅读以下说明及Visual Basic程序代码，将应填入(n)处的字句写在对应栏内。

【说明】

以下程序为求行列式X(5,5)的值S。

【Visual Basic代码】

Private Function col (byval x (5,5 ) as integer ) as long

dim fesult as long

dim temp as long

dim I as integer

dim j as integer

dim k as imeger

result = 0

for I = to 5

(1)

for j = 1 to 5

if I+j＞6 then

k= (1+j ) mod 5

else

k=1

endif

temp=temp*x (k,j )

(2)

result=(3)

(4)

(5)

End function
