紧急跪求一算法，分不够可加！！
0到9十个数中，我想得到一些组合数，这些组合数的规则是总共分为三个组，A，B，C 组，其中A和B组里面是0到九之间的任意三个数，但不可重复，剩下的四个数放到C组中，然后我想得到就是这种规则的组合共同多少种，并列举出来。
比如：
A：012 B：965 C：3478
以上只是其中的一种，就是这种格式！
在此谢过，重谢！！
[解决办法]
Private Sub Command1_Click()
lst.Clear
For i = 12 To 987
If IsRightNumber(i) = True Then
For j = 12 To 987
If IsRightNumber(j) = True And HaveSameNumber(i, j) = False Then
lst.AddItem ( "A= " & i & "; B= " & j)
End If
Next
End If
DoEvents
Next
End Sub
Private Function IsRightNumber(ByVal num As Integer) As Boolean
Dim sTmp As String
sTmp = num
Do While Len(sTmp) < 3
sTmp = "0 " + sTmp
Loop
Dim A, B, c
A = Left(sTmp, 1)
B = Mid(sTmp, 2, 1)
c = Right(sTmp, 1)
If A = B Or A = c Or B = c Then
IsRightNumber = False
Exit Function
End If
IsRightNumber = True
End Function
Private Function HaveSameNumber(ByVal num1 As Integer, ByVal num2 As Integer)
Dim A As String
Dim B As String
A = Right( "000 " & num1, 3)
B = Right( "000 " & num2, 3)
For i = 1 To 3
If InStr(A, Mid(B, i, 1)) > 0 Then
HaveSameNumber = True
Exit Function
End If
Next
HaveSameNumber = False
End Function
顯示太多了﹐只給出前兩個數的算法﹐第三個數很簡單﹐你自已取剩下的4個數的不同排列組合就可以了
