VBA计算某个集合中哪6个数字的和为…

A列中从A1到A20分别为数字1-20

B1为100，为计算的结果（6个数的和）

现在计算A列中哪6个数字的和为100

符合条件的就放在C列中

 

Sub
CountTotal()

Application.ScreenUpdating = False

Range("c:c").ClearContents

Dim a%, b%, c%, d%

Dim e%, f%

Dim x%, tmp As String, K, totalco As Integer

Dim dic

Set dic = CreateObject("scripting.dictionary")

x =
Range("a65536").End(xlUp).Row

For a = 1 To x
- 5

    For b = a +
1 To x - 4

       
For c = b + 1 To x - 3

           
For d = c + 1 To x - 2

               
For e = d + 1 To x - 1

                   
For f = e + 1 To x

                       
If Cells(a, 1) + Cells(b, 1) + Cells(c, 1) + Cells(d, 1) + Cells(e,
1) + Cells(f, 1) = [B1] Then

                           
tmp = Cells(a, 1) & " + " &
Cells(b, 1) & " + " & Cells(c, 1)
& " + " & Cells(d, 1)
& " + " & Cells(e, 1)
& " + " & Cells(f, 1)
& " = " & [B1]

                           
dic.Add tmp, ""

                       
End If

                   
Next

               
Next

           
Next

       
Next

    Next

Next

totalco = dic.Count

'K = dic.keys

'For x = 0 To totalco - 1

'Cells(x + 1, 3) = K(x)

'Next

[C1].Resize(dic.Count, 1) = Application.Transpose(dic.keys)
'这个语句也可以用上面四句来完成

MsgBox "共有" & totalco &
"条符合记录的！"

Application.ScreenUpdating = True

End Sub

 

自己感觉这样的算法速度似乎比较慢

慢慢再琢磨有没有快点的算法

如果A列中的数字越多，算起来就越慢了。

类似的过程别人早就有了，只是人家用别的算法（自己写的看得明白，别人写的看起来好费劲

）
