当n的值为10时，关于该两段程序，下列说法不正确的是(  )

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

Dim a(1 To 10) As Integer, f(1 To 20) As Boolean

    'f数组各元素的初值设为False，代码略

    For i = 1 To 10

       t =int(rnd()*20+1)

       If Not f(t) Then

          a(i) = t:      ⑴     

          For j = i To 2 Step -1

             If    ⑵    Then

                tmp = a(j): a(j) = a(j - 1): a(j - 1) = tmp

             End If

          Next j

       Else

               ⑶    

       End If

    Next i

上述程序中3处下划线应填入的程序代码是（  ）

执行这部分流程，输入11，变量i和f的值分别是（  ）
