wps函数自动组成不同数字组合
比如12345是母数字。我想知道在这5个数学可以组合成多少个组合。组成13245或者35421组成更多个组合的排位
这是数学中的排列问题。
A（5，5）=5！/（5-5）！=5！=5×4×3×2×1=120（种）
Sub 排列()
Dim cm(1 To 120, 1 To 5)
ST = Timer
For a1 = 1 To 5
For a2 = 1 To 5
If a2 = a1 Then GoTo 100
For a3 = 1 To 5
If a3 = a2 Or a3 = a1 Then GoTo 200
For a4 = 1 To 5
If a4 = a3 Or a4 = a2 Or a4 = a1 Then GoTo 300
For a5 = 1 To 5
If a5 = a4 Or a5 = a3 Or a5 = a2 Or a5 = a1 Then GoTo 400
n = n + 1
For i = 1 To 5
If a1 = i Then cm(n, 1) = i
If a2 = i Then cm(n, 2) = i
If a3 = i Then cm(n, 3) = i
If a4 = i Then cm(n, 4) = i
If a5 = i Then cm(n, 5) = i
Next i
400 Next
300 Next
200 Next
100 Next
Next
Range("A1:E120") = cm
Cells(1, 8) = "排列数"
Cells(1, 9) = n
Cells(2, 8) = "运行时间(秒)"
Cells(2, 9) = Timer - ST
End Sub
