Checking Two Sets of Arrays

[amin84]

Hello,

I have two sets of arrays. The first one is an output from user which can be any set of numbers. The second array has a list of 0-9 with A-J listed. I want to check every item in the first array and see which alphabet it represents. Sorry I couldn't come up with a better example than this. Any one knows how to check this?

#include 
Global $output[14]=['3','4','2','2','5','4','6','6','2','7','6','4','3','4']
Global $chart[10][2]=[ _
['1','A'], _
['2','B'], _
['3','C'], _
['4','D'], _
['5','E'], _
['6','F'], _
['7','G'], _
['8','H'], _
['9','I'], _
['0','J']]
;So the final output would be: "CDBBEDFFBGFDCD"

Pseudo code:

Loop through array $output

Loop through array $chart

if element of $output = element of $chart Then

do whatever needs to be done

EndIf

Endloop

Endloop

Awesome. Tnx. Here is the final script.

#include 
Global $output[14]=['3','4','2','2','5','4','6','6','2','7','6','4','3','4']
Global $chart[10][2]=[ _
['1','A'], _
['2','B'], _
['3','C'], _
['4','D'], _
['5','E'], _
['6','F'], _
['7','G'], _
['8','H'], _
['9','I'], _
['0','J']]
;So the final output would be: "CDBBEDFFBGFDCD"
$converted = ''
For $o=0 To UBound($output)-1
For $c=0 To UBound($chart,1)-1
If $output[$o]==$chart[$c][0] Then
$converted &= $chart[$c][1]
EndIf
Next
Next
ConsoleWrite($converted&@LF)

To enhance performance you should leave the inner loop as soon as to entries match:

#include
Global $output[14] = ['3', '4', '2', '2', '5', '4', '6', '6', '2', '7', '6', '4', '3', '4']
Global $chart[10][2] = [ _
        ['1', 'A'], _
        ['2', 'B'], _
        ['3', 'C'], _
        ['4', 'D'], _
        ['5', 'E'], _
        ['6', 'F'], _
        ['7', 'G'], _
        ['8', 'H'], _
        ['9', 'I'], _
        ['0', 'J']]
;So the final output would be: "CDBBEDFFBGFDCD"
$converted = ''
For $o = 0 To UBound($output) - 1
    For $c = 0 To UBound($chart, 1) - 1
        If $output[$o] == $chart[$c][0] Then
            $converted &= $chart[$c][1]
            ExitLoop  ; <====
        EndIf
    Next
Next
ConsoleWrite($converted & @LF)

Tnx for the tip.

isn't it easier to have it like:

[1] = 'A'

[2] = 'B'

then it could be done with 1 loop. Correct me if I am wrong.

Correct. Then the code would look like this:

Global $output[14] = ['3', '4', '2', '2', '5', '4', '6', '6', '2', '7', '6', '4', '3', '4']
Global $chart[11] = ['', 'A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J']
;So the final output would be: "CDBBEDFFBGFDCD"
$converted = ''
For $o = 0 To UBound($output) - 1
    $converted &= $chart[$output[$o]]
Next
ConsoleWrite($converted & @LF)

replacing values in the original:

#include <Array.au3>
Global $output[14] = ['3', '4', '2', '2', '5', '4', '6', '6', '2', '7', '6', '4', '3', '4']
Global $chart[11] = ['', 'A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J']
$converted = ''
For $i = 0 To UBound($output) - 1
    $output[$i] = $chart[$output[$i]]
Next
_ArrayDisplay ( $output)

I simplified the example here. In my own script I can't use only one loop cuz none of the arrays are numbers to use them as index number for the other one. I'm converting different Persian Unicode systems to each other.

But good optimization.
