GetCombinations UDF

7 posts in this topic

#1 ·  Posted (edited)

well... i dont really know how to explain what this function does but i will try :D

this function generates all possible combinations for a string.. i think i should just give an example:

if you put in "ab" then it will return an array containing:

the number of combinations (in this case 6)

a

b

aa

ab

ba

bb

(of course you can do this with numbers or other letters too)

whatever, heres the UDF

Func GetCombinations($sString)
    Local $aString = StringSplit($sString, "")
    Local $iPossibilities = 0
    Local $k
    For $k = 1 To $aString[0]
        $iPossibilities += $aString[0] ^ $k
    Next
    Local $aReturn[$iPossibilities + 1] = [$iPossibilities]
    Local $i = 0
    Local $LastString = ""
    Local $CalcBack = 1
    While $i < $aReturn[0]
        If $CalcBack > 1 Then
            $LastString = $aReturn[$i + 1 - $CalcBack]
        EndIf
        For $j = 1 To $aString[0]
            $aReturn[$i + $j] = $LastString & $aString[$j]
        Next
        $CalcBack += $aString[0] - 1
        $i += $aString[0]
    WEnd
    Return $aReturn
EndFunc

calling the following will print the same example as above but in a messagebox

Func Print($String)
    Local $a = GetCombinations($String)
    Local $i
    Local $s = ""
    For $i = 1 To $a[0]
        $s &= $a[$i] & @CRLF
    Next
    MsgBox(0, $a[0], $s)
EndFunc

Print("ab")

sadly the maximum length of your inputstring is 7 letters because the function saves the combinations in an arrays and the arraysize is limited (7 letters produce 960799 combintaions!) so this is just usefull for learning something about arrays and... logic :wacko:

hope you like it, Mikon

Nice!

this is fun, but 2 things i'd sugest trying to do

1- make the fist space of the array contain the total number of combonations, so if thats all you wanted, and not an example of each, it would be easily accessable

2- Get rid of the limit if you can, i want to try 123456789, but it wont let me :D

nice! Now I can correctly do the math for my GUID GENERATOR function :D

This is a nice function, and will come very handy.

just do...

scratch what i wrote, after looking at some numbers i relized i suck at math. lol.

btw,

I love your personal message(the text or whatever under your avatar).

HI,

you can change this way.

#include<Array.au3>

Print("ab")

Func Print($String)
    Local $a = GetCombinations($String)
    _ArrayDisplay($a, "Combinations")
EndFunc

Func GetCombinations($sString)
    Local $aString = StringSplit($sString, '')
    Local $iPossibilities = 0
    For $k = 1 To $aString[0]
        $iPossibilities += $aString[0] ^ $k
    Next
    Local $aReturn[$iPossibilities + 1] = [$iPossibilities]
    Local $LastString = ''
    Local $CalcBack = 1
    Local $i = 0
    
    While $i < $aReturn[0]
        If $CalcBack > 1 Then
            $LastString = $aReturn[$i + 1 - $CalcBack]
        EndIf
        For $j = 1 To $aString[0]
            $aReturn[$i + $j] = $LastString & $aString[$j]
        Next
        $CalcBack += $aString[0] - 1
        $i += $aString[0]
    WEnd
    Return $aReturn
EndFunc

So long,

Someone made a Permutate function before where for 123 it gave out

123

132

213

231

312

321

I remember trying it for 123456789 and it took bloody ages

In your UDF you should use _ArrayAdd to remove the limit

i dont think _ArrayAdd can increase the possible size of an array. it just "Adds a specified value at the end of an array, returning the adjusted array."

so this probably wont help :D

Oh i get you now, I was thinking that you had hardcoded the array size. It was yesterday I looked at the code. Sorry
