[SOLVED]Count duplicates in an array

8 posts in this topic

#1 ·  Posted (edited)

Hello everyone,

I just have a beginner question: is there a way to count duplicates in an array? If you don't see what I mean, here is an example of what I mean:

$arr[5] = ['a', 'a', 'b', 'b', 'c'] ; the array

countDuplicates($arr); Representing the data in a bidimensionnal array, this would return:

#cs
['a'][2]
['b'][2]
['c'][1]

Of course this is a bit messy, but that's just for you to get the idea
#ce

I'm trying to achieve this to check whether yes or no an array has more or same amount of occurrences of a character than another array.

Am I doing this the right way?

Does such a function exist?

Thanks for everything :)

There is no func (@Dev's please correct when wrong) to this job. But you can solve like this:

#include <Array.au3>

$txt = ""
For $i=0 to 100
    $txt &= Random(1,30,1)&@CRLF
Next



;$txt = FileRead('test.txt') ;if txt is ia in a file

;startpoint
;ConsoleWrite($txt & @CRLF)
_ArrayDisplay(_countUniqueNumbers($txt), '_countUniqueNumbers')

Func _countUniqueNumbers($sText='Test', $sDelim=@CRLF)
    ;ConsoleWrite($sText & @CRLF)
    ;returns the count of each unique number in a String
    ;autor: autobert (autoit.de) 11/2009
    $sText = @CRLF&StringReplace($sText, ' ', '')
    $sText = StringReplace($sText, $sDelim, $sDelim & ' ')
    $aSource = StringSplit($sText, $sDelim, 3)
    _ArrayDelete($aSource, 0)
    ;_ArrayDisplay($aSource,'Original')
    $aUnique = _ArrayUnique($aSource)
    _ArrayDelete($aUnique, 0)
    Dim $aUnique2D[UBound($aUnique)][2]
    For $x = UBound($aUnique) - 1 To 0 Step -1
        $aUnique2D[$x][0] = $aUnique[$x]
        StringReplace($sText, $aUnique[$x] & $sDelim, 'a')
        $aUnique2D[$x][1] = @extended
        If StringStripWS($aUnique2D[$x][0],8)='' Then _ArrayDelete($aUnique2D,$x)
    Next
    _ArraySort($aUnique2D)
    Return $aUnique2D
EndFunc   ;==>_countUniqueNumbers

Try this :

#Include <Array.au3>

Local $arr = ['a', 'a', 'b', 'b', 'c', 'e', 'f', 'a'] 
Local $aDup = _ArrayCountOcc($arr, 2)
_ArrayDisplay($aDup)

; iOrdByNumber = 0 : Do not sort
;                1 : Sort by number of occurences
;                2 : Sort by number of occurences, in descending order
Func _ArrayCountOcc($aArray, $iOrdByNumber = 0)
    If UBound($aArray, 0) <> 1 Then Return SetError(1, 0, 0)
    If Not IsInt($iOrdByNumber) Or $iOrdByNumber < 0 Or $iOrdByNumber > 2 Then Return SetError(2, 0, 0)
    Local $aRet[UBound($aArray)][2], $last, $iIndex = 0
    _ArraySort($aArray)
    For $i = 0 To UBound($aArray) - 1
        If $aArray[$i] = $last And $i <> 0 Then
            $aRet[$iIndex - 1][1] += 1
        Else
            $aRet[$iIndex][0] = $aArray[$i]
            $aRet[$iIndex][1] = 1
            $last = $aArray[$i]
            $iIndex += 1
        EndIf
    Next
    Redim $aRet[$iIndex][2]
    If $iOrdByNumber Then _ArraySort($aRet, ($iOrdByNumber = 2 ? 1 : 0), 0, 0, 1)
    Return $aRet
EndFunc

Sorry first example was to count in text, this one is for counting in array:

#include <Array.au3>

#cs
Dim $aArray[101]
For $i=0 to 100
    $aArray[$i] = Random(1,30,1)
Next
#ce
Local $aArray[5]    = ["a", "a", "b", "b", "c"]
_ArrayDisplay(_countUniqueElements($aArray), '_countUniqueElements')

Func _countUniqueElements($aSource)
    ;returns the count of each unique element in a Array
    ;autor: autobert
    Local $aUnique = _ArrayUnique($aSource)
    _ArrayDelete($aUnique, 0)   
    Dim $aUnique2D[UBound($aUnique)][2]
    For $x = 0 to UBound($aUnique) - 1 
        $aUnique2D[$x][0] = $aUnique[$x]
        $aCount=_ArrayFindAll($aSource,$aUnique[$x])
        $aUnique2D[$x][1] = UBound($aCount)
    Next
    _ArraySort($aUnique2D)
    Return $aUnique2D
EndFunc   ;==>_countUniqueElements^

#include<array.au3>

Local $aArray[8]    = ["a", "a", "b", "b", "c" , "c" , "c" , "d"]

Local $aOut[0][2]

for $i = ubound($aArray) - 1 to 0 step -1
        $aFound = _ArrayFindAll($aArray , $aArray[$i])
        _ArrayAdd($aOut , $aArray[$aFound[0]] & "|" & ubound($aFound) ,  0)
        _ArrayDelete($aArray , _ArrayToString($aFound , ";"))
        $i -= ubound($aFound) - 1
next

_ArrayDisplay($aOut)

      Hi,
      I am struggling converting my 1D array to a 2D array and then showing that in my List View. Below is my current code, where I would like to take the array from the input box, and have that displayed as a list within the list view this is a list of computer names, and then update the 2nd column of each line once I have ran a ping and a registry change on each computer name, with either 'Completed' and 'Failed'
      I have checked out the AutoIt Arrays page here: https://www.autoitscript.com/wiki/Arrays , but unfortunately I cannot get my head around it. Any help would be greatly appreciated.
      I hope this makes sense.
      Thanks

      Hey Guys,
       
      So, the functions work, where primarygui() accurately determines the evaluation of the status of the checkboxes - the msgbox picks this up.
       
      However, later on, when we re-enter a 'for $i = 0 to ubound($checkbox)' loop, then in the 'batchinitial' function it doesn't picked up that the status&$i = 1, so it jumps out, then within the While 1 loop, it exits the loop in the first row, again because the status& $i= 0
      The "assign" line within the primarygui funtion, is this only a local assignment? if so, how can I make it cross function?
       
      Thank in adv for your help

      Hello,
      I'm building whit mine limited coding know-how a AI in Autoit....
      Just because..... why not
      It's not doing what i tought it would do.
      I hope somebody could help me whit this script?
      so far :
      -building an learning grid --> AI needs to guess the label in the grin whit only the X and Y value.
      -Building an array filled whit random values as weights.
      -quess the label
      -learn - if quess not the same as the label go change the weights

      At this point (the changing of the weights) I've some strange result and hope somebody could point me in the right direction
      I think that the problem is in the formula for changing the weights.

      PS. I'm also open for good coding practice   I'm learning coding as i go

      All,
      I'm working on automating the update process for a piece of software that we use at my company. The installer file always contains the version number as a part of the file name (eg InstallFile_9342.msi) and the numbers always change with every update.
      How do I use AutoIt to run the program? I know I can't use a wildcard in place of the numbers when using the "Run" command. 
      I tried 
      Local $aArray = _FileListToArray("C:\path\to\file", "InstallFile_*.msi", 0, 1) Run("$aArray") and I also tried
      Local $bInstall = FileFindFirstFile("InstallFile_*.msi") Run("$bInstall") and neither worked. 
      Can someone please point me in the right direction? I've done some searching on the forum and haven't found anyone in a similar situation before.
      Thanks!

      I have a program that has a control that changes color a few seconds into running. So ideally, I would poll this to tell when an event has occurred. 
      I can't seem to retrieve the correct color value for a control. It always seems to return white indicating that its selecting somewhere else in the window.
      In the PixelGetColor call I'm adding half the width to the x value and subtracting half the height to the y value  in order to get the center of the control. (assuming the coords returned by ControlGetPos are top left - which i can't be sure of) But I've also tried without modifying the x/y and with changing the PixelCoordMode option to 2. Maybe I'm making a silly mistake and can't see it? Any help would be appreciated.
      Code is below:
      Opt("PixelCoordMode", 0)
      FileChangeDir( "C:\Where\My\File\Is" );
      Run( "MyProgram.exe" )
      Local $hClient = WinWaitActive( $CLIENT_TITLE, "", 10 )
      Local $systemIndicatorClassNN= "[CLASS:Qt5QWindowIcon; INSTANCE:99]"
      Local $hSystemIndicator = ControlGetHandle ( $hClient, "", $systemIndicatorClassNN)
      Local $xywh = ControlGetPos ( $hClient, "", $hSystemIndicator )
      For $i = 10 To 1 Step -1
            $color = PixelGetColor ( $xywh[0] + ($xywh[2]/2), $xywh[1] - ($xywh[3]/2), $hClient )
            LogToFile( $color )
            Sleep( 2000 )
      Next
