实现上述功能的VB程序代码如下，请在划线处填上合适的代码。

Dim a( 1 To 20) As Integer

Private Sub Command1_Click ( )

Dim key As Integer

key =   ①   

i = 1

Do While key > a ( i ) And ( i <= 1 5 )

i = i + 1

Loop

Label4.Caption = “该数插入的位置是：” + Str ( i )

If  i = 16  Then

a ( i ) = key

Else

For j = 16  To  i + 1 Step -1

    ②  

Next j

a ( i ) = key

End  If

List2. Clear

For i = 1 To 16

List2.AddItem a( i)

Next i

End Sub

Private Sub Form_Load( )

'随机生成15个200以内的正整数

Randomize

For i = 1 To 15

a ( i ) = Int(Rnd * 200) + 1

Next i

'将15个数从小到大排序

For i = 1 To 14

k = i

For j = i + 1 To 15

If a ( k ) > a ( j ) Then k = j

Next j

If  i <>k  Then

t = a(i)； a( i) = a ( k )：a ( k )

End  If

Next i

'将排好序的数输出在列表框Listl中

Listl.Clear

For i = 1 To 15

Listl.AddItem str ( a ( i ) )

Next i

End Sub

程序中①划线处应填入{#blank#}1{#/blank#}，程序中②划线处应填入{#blank#}2{#/blank#}

  Function fac(n As Integer) As Long

    fac = 1

    For i = 1 To n

fac = fac * i

    Next i

End Function

Private Sub Command1Click()

Dim s  As Long, j As Integer

For j = 1 To 10

Next

Text1.Text = Str(s)

End Sub

 方框中的正确语句是：（   ）

x = InputBox("输入x的值：")

If x > 3 Then

   If x <= 6 Then

     y = 2 * x

   Else

     y = 3 * x

   End If

Else

   y = 4 * x

End If

Print y若x、y均是整型变量，程序运行并输入6，则y的值是（   ）
