Permutation combination of a 4 digit no
 

Hi,

Try this courtesy of John Walknenbach:-

Dim CurrentRow

Sub GetString()
Dim InString As String
InString = InputBox("Enter text to permute:")
If Len(InString) < 2 Then Exit Sub
If Len(InString) = 8 Then
MsgBox "Too many permutations!"
Exit Sub
Else
ActiveSheet.Columns(1).Clear
CurrentRow = 1
Call GetPermutation("", InString)
End If
End Sub

Sub GetPermutation(x As String, y As String)
' The source of this algorithm is unknown
Dim i As Integer, j As Integer
j = Len(y)
If j < 2 Then
Cells(CurrentRow, 1) = x & y
CurrentRow = CurrentRow + 1
Else
For i = 1 To j
Call GetPermutation(x + Mid(y, i, 1), _
Left(y, i - 1) + Right(y, j - i))
Next
End If
End Sub

Left(y, i - 1) + Right(y, J - i))
Next
