编写一个验证哥德巴赫猜想的VB程序:程序运行时，在文本框Text1中输入一个大于或等于4的偶数，单击“验证”按钮Command1后，如果哥德巴赫猜想验证成功，则在文本框Text2中显示“Yes”，并在列表框List1中显示用两个素数表示该偶数的等式，否则显示“No”。程序运行效果如图所示。

实现上述功能的VB代码如下，但加框处代码有错，请改正。

Function judge(x As Integer)As Boolean

 ‘函数judge的功能是判断整数x是不是素数，若是素数则返回True，否则返回False

 Dim j As Integer

 judge=True

 j=2

 Do While j<=x-1 And judge=True

If x Mod j=0 Then

judge=False

Else

j=j+1

End If

 Loop

End Function

Private Sub Command1_Click()

 Dim n As Integer, p As Integer, q As Integer, flag As Boolean

 n=Val(Text1.Text)

 p=1

 flag=False

 Do While  And p<n    ‘{#blank#}1{#/blank#}

 p=p+1

      ‘{#blank#}2{#/blank#}

If judge(p)And judge(q)Then

Text2.Text=“Yes”

flag=True

List1.AddItem Str(n)+“=”+Str(p)+“+”+Str(q)

  End If

 Loop

 If flag=False Then

Text2.Text=“No”

End Sub

实现上述功能的VB代码如下，请完善代码：

Private Sub Command1_Click()

Dim n As Integer, i As Integer, t As Integer,sum As Long,s As String

n=Val(Text1.Text)

For i = 1 To n^3 Step 2     ‘变量i表示连续奇数的首个整数

 sum=0:t = i:flag = False

 Do While sum <= n^3 And flag = False

  sum ={#blank#}1{#/blank#}

  t = t +2

  If{#blank#}2{#/blank#}Then flag = True

 Loop

 If flag = True Then Exit For

Next i

s = Str(n) + “^”+ Str(3) + “=”

Do While sum >0

{#blank#}3{#/blank#}

 If sum = 0 Then

  s = s + Str(i)

 Else

  s = s + Str(i) +“+”

 End If

 i = i + 2

Loop

Text2.Text = s

End Sub

a(1) = "231": a(2) = "34": a(3) = "23": a(4) = "234": a(5) = "123"

For i = 1 To 2

    For j = 1 To 5 - i

       If a(j) > a(j + 1) Then t = a(j): a(j) = a(j + 1): a(j + 1) = t

   Next j

   Text1.text=a(j)

Next i

执行该程序段后，文本框Text1显示的内容为（    ）
