AutoIT - Check if the values or some of the values from an array are also in another array

[Renderer]

Hello guys, I've got a little question: How do I check if the values or some of the values from an array ($alphabet) are also in the other array ($word)?

Like:

$alphabet[26] = [A,B,C,D,E,F,G, ...]

$word = [H,E,L,L,O]

How do I check if the values from $alphabeth (in this case H,E,L,L,O) are in the array called $word?

Thanks in advance!

In this example:-
The function IsArray1SomeInArray2() answers your first question of post #1.
The function IsArray1InArray2() answers your second question of post #1.

An optional case sensitivity parameter is added to answer one of my questions.

#include <Array.au3>

Local $sAlphabet = "ABCDEFGHIJKLMOPQRSTUVWXYZ"
$aAlphabet = StringSplit($sAlphabet, "", 2)

Local $sWord = "hello" ; "HELLO" ; "Hello" ;
$aWord = StringSplit($sWord, "", 2)

MsgBox(0, "IsArray1SomeInArray2()", "One or more of the elements of Array1" & (IsArray1SomeInArray2($aWord, $aAlphabet, 0) ? " are in " : " are NOT in ") & "Array2")

MsgBox(0, "IsArray1InArray2()", "All the elements of Array1" & (IsArray1InArray2($aWord, $aAlphabet, 0) ? " are in " : " are NOT in ") & "Array2")


; Checks if some of the values from array1 ($word) are also in the array2 ($alphabet); also,
; Checks if some of the values from array1 ($alphabet) are also in the array2 ($word).
Func IsArray1SomeInArray2($Array1, $Array2, $iCase = 0) ; $iCase = 0 (case insensitive, "h" = "H")
    $Array1 = _ArrayUnique($Array1, 0, 0, $iCase, $ARRAYUNIQUE_NOCOUNT)
    $Array2 = _ArrayUnique($Array2, 0, 0, $iCase, $ARRAYUNIQUE_NOCOUNT)
    Return UBound(StringRegExp(_ArrayToString($Array2), ($iCase ? "" : "(?i)") & _ArrayToString($Array1), 3)) > 0
EndFunc   ;==>IsArray1SomeInArray2

; Checks if all of the values from array1 ($word) are also in the array2 ($alphabet)
Func IsArray1InArray2($Array1, $Array2, $iCase = 0)
    $Array1 = _ArrayUnique($Array1, 0, 0, $iCase, $ARRAYUNIQUE_NOCOUNT)
    $a = StringRegExp(_ArrayToString($Array2), ($iCase ? "" : "(?i)") & _ArrayToString($Array1), 3)
    Return UBound($Array1) = UBound($a)
EndFunc   ;==>IsArray1InArray2

If you do not understand something  in either function, I suggest you use as many  ConsoleWrite(  [Insert variable here]  & @CRLF)'s as needed, together with AutoIt's help file.  Just as I have done, do, and will do.  In SciTE, I use "cw ", that is, "cw" followed by a space - a shortcut.

An other way could be Scripting.Dictionary

;Local $sAlphabet = "ABCDEFGHIJKLMOPQRSTUVWXYZ"
Local $sAlphabet = "ABCDEFGHIJKL"
$aAlphabet = StringSplit($sAlphabet, "", 2)
Local $sWord = "Hello" 
$aWord = StringSplit($sWord, "", 2)

Local $sdAlphabet = ObjCreate("Scripting.Dictionary"), $count
$sdAlphabet.CompareMode = 1   ; case insensitive
For $i In $aAlphabet
    $sdAlphabet.Item($i)  ; populate the dictionary
Next
For $i In $aWord
    If $sdAlphabet.Exists($i) Then $count += 1  ; then check
Next

Msgbox(0,"", $count & " values out of " & UBound($aWord) & " from $aWord exist in $aAlphabet")

This behavior might not be 100% kosher

#include<array.au3>

local $aLphabet[8] = ['A','B','D','F','G','H','I' ,'O']
local $aWord[5] = ['H','E','L','L','O']

_ArrayDisplay(StringRegExp(_ArrayToString($aWord , ',') , _ArrayToString($aLphabet , '|') , 3) , 'Matches')

in the array returned by this function you will have:
in column 1, elements belonging only to array 1;
in column 2, elements belonging only to array 2;
in column 3, elements belonging to both arrays
p.s. it's a case sensitive function

#include <Array.au3>

Local $sAlphabet = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
$aAlphabet = StringSplit($sAlphabet, "", 2)

Local $sWord = "HELLO" ; "hello" ; "Hello" ;
$aWord = StringSplit($sWord, "", 2)

_ArrayDisplay(_Separate($aAlphabet, $aWord))

Func _Separate(ByRef $in0, ByRef $in1)
    $in0 = _ArrayUnique($in0, 0, Default, Default, 0)
    $in1 = _ArrayUnique($in1, 0, Default, Default, 0)
    Local $z[2] = [UBound($in0), UBound($in1)], $low = 1 * ($z[0] > $z[1]), $aTemp[$z[Not $low]][3], $aOut = $aTemp, $aNdx[3]
    For $i = 0 To $z[Not $low] - 1
        If $i < $z[0] Then $aTemp[$i][0] = $in0[$i]
        If $i < $z[1] Then $aTemp[$i][1] = $in1[$i]
    Next
    For $i = 0 To $z[$low] - 1
        $x = _ArrayFindAll($aTemp, $aTemp[$i][$low], 0, 0, 1, 0, Not $low)
        If Not @error Then ; both
            For $j = 0 To UBound($x) - 1
                $aTemp[$x[$j]][2] = 1
            Next
            $aOut[$aNdx[2]][2] = $aTemp[$i][$low]
            $aNdx[2] += 1

Indeed . Don't know if it's for laziness or for conenience, but I prefer don't reinvent the wheel when I can

Yes, it could be pinned
Guess where does my previous code come from ?

Not the cleanest example yet but serves it well  

#include <Array.au3>
MsgBox(262144, 'is_FullMatch', _Match("ABCDEFGHIJKLMOPQRSTUVWXYZ", "HELLO"))

Func _Match($sStringFrom, $sWord)
    Local $aWord = StringSplit($sWord, "", 3)
    $sWord = _ArrayToString(_ArrayUnique($aWord, 0, 0, 0, 0), "")
    Local $Ret = UBound(StringRegExp("|" & _ArrayToString(StringSplit($sStringFrom, "", 3)), "(?i:[|" & $sWord & "])+\w", 3))

    MsgBox(262144, "", StringLen($sStringFrom) - $Ret & " Unique Matches from " & StringLen($sWord))
    Return StringLen($sWord) = StringLen($sStringFrom) - $Ret
EndFunc   ;==>_Match
