单击“计算”按钮Command1后，则在文本框Text2中显示的内容是{#blank#}1{#/blank#}，在文本框Text3中显示的内容是{#blank#}2{#/blank#}。

  Private Sub Command1Click()

Dim s As Integer, t As Integer, n As Integer

n = Val(Text1.Text)

t = 0

s = 0

For i = 1 To n

     If Int(Sqr(i)) = Sqr(i) Then

        s = s + i

        t = t + 1

     End If

Next i

Text2.Text = Str(t)

Text3.Text = Str(s)

End Sub

Const n = 8

Dim a(1 To n) As Integer

For i = 1 To n

    a(i) = Int(Rnd * 20)

Next i

x = n \ 2

For i = x To 2 Step -1

    For j = 1 To i - 1

      If a(j) < a(i) Then

        t = a(j): a(j) = a(i): a(i) = t

      End If

    Next j

Next i

i = n

Do While i > x + 1

    k = i

    For j = i - 1 To x + 1 Step -1

      If a(j) > a(k) Then k = j

    Next j

    If k <> i Then

      t = a(k): a(k) = a(i): a(i) = t

    End If

    i = i - 1

Loop

执行完这段代码后，数组 a 中各个元素的值可能的是（  ）

a(1)=2: a(2)=6: a(3)=8: a(4)=9: a(5)=12

a(6)=15: a(7)=17: a(8)=18: a(9)=22: a(10)=30

k=Val(Text1.Text)

i=1: j=10

Do While i <=j

 m=(i+j) \ 2

 If a(m) <=k Then

    i=m+1

 Else

    j=m-1

 End If

Loop

Text2.Text=Str(a(i))+"← →"+Str(a(j))

程序运行时，文本框Text1中输入5，文本框Text2中显示的内容是（  ）
