Private Sub Command1_Click()

Dim a(1 To 10) As Integer, b(1 To 10) As Integer

Dim n As Integer, i As Integer

  n = 3

  For i = 1 To 5

    a(i) = i

    b(n) = 2 * n + i

 Next i

 Text1.Text = Str(a(n))

 Text2.Text = Str(b(n))

End Sub

程序运行后，单击命令按钮，在文本框Text1和Text2上显示的结果分别是（  ）

Dim tmp As Integer

Dim a(1 To 10) As Integer

Private Sub Command1_Click()

  For i=2 To 10

Text1.Text = ""

For i= 1 To 5

  For j=i+1 To 6

  If s(i) + s(i) < s(j) + s(i) Then

    t= s(j): s(j)= s(i): s(i)=t

  End If

  Next j

Next i

For i=1 To 6

  Text1.Text = s(i) + Text1.Text

Next i

  If  Then

    tmp = a(i)

      For j=  To 1 Step -1    ‘依次后移

        If tmp > a(j) Then Exit For

        a(j+1)= a(j)

      Next j

          ‘插入数据

    End If

  Next i

  For i= 1 To 10

    List1.Addltem a(i)

  Next i

End Sub

要实现上述功能，方框①②③中的语句分别是（  ）
