一个含有n个元素的整数数组，如果数组两个连续元素之间差的绝对值包括了[1,n-1]之间的所有整数，则称之为一组“完美跳数”。小余制作了验证完美跳数的VB程序，功能如下：在文本框Text1中输入一组以逗号分隔且以逗号结尾的整数数组，单击“验证”按钮Command1，在标签Label1中显示验证结果，运行界面如图所示。
Private Sub Command1_Click()
Dim n As Integer, i As Integer, j As Integer
Dim a(1 To 100) As Integer, b(1 To 100) As Integer Dim s As String, chr As String, temp As String
s = Text1.Text
i = 1: n = 0
Do While i <= Len(s)
ch = Mid(s, i, 1)
If ch >= "0" And ch <= "9" Then
temp = temp + ch
Else
n = n + 1
①
temp = ""
End If
i = i + 1
Loop
For i = 2 To n
②
Next i
For i = 1 To n - 2
For j = 
If b(j) < b(j - 1) Then
t = b(j): b(j) = b(j - 1): b(j - 1) = t
End If
Next j
Next i
For i = 1 To n - 1
If b(i) <> i Then Exit For
Next i
If i = n Then Label1.Caption = "完美跳数" Else Label1．Caption = "非完美跳数"
End Sub
