# Array question.

## Recommended Posts

Hello AutoIt people,

I'm trying to create a function that will tell whether the two arrays \$x and \$y with the same index limit \$no are equal---equal in the sense that an element of \$x has a corresponding equal element on \$y. The function will return "True" if that's the case and "False" if otherwise.

```#include-once
; . . . . .
Func _IsArrayEquivalent(ByRef \$x, ByRef \$y)

If Ubound(\$x) = Ubound(\$y) Then
\$no = Ubound(\$x)
\$count1 = 0
For \$countx = 0 to \$no - 1 Step +1
For \$county = 0 to \$no - 1 Step +1
If \$x[\$countx] = \$y[\$county] Then
\$county = \$no - 1
\$count1 += 1
EndIf
Next
Next

\$count2 = 0
For \$county = 0 to \$no - 1 Step +1
For \$countx = 0 to \$no - 1 Step +1
If \$y[\$county] = \$x[\$countx] Then
\$countx = \$no - 1
\$count2 += 1
EndIf
Next
Next

If \$count1 = \$no And \$count2 = \$no Then
Return "True"
Else
Return "False"
EndIf

Else
Return "False"
EndIf
EndFunc

; T R I A L
Dim \$a[4] = ["Ba", "Ba", "Bi", "Bi"], \$b[4] = ["Ba", "Bi", "Bi", "Bi"]

msgbox(0,"", _IsArrayEquivalent(\$a, \$b))```

The problem is that it is limited to those arrays whose every element occurs only once. So, the trial I did above will return "True" even though it should be false.

See Ubound() in the help file.

`MsgBox(0, "Result", Ubound(\$x) = Ubound(\$y))`

Do you mean that all elements of \$x have a corresponding equal element on \$y ?

Yessir.

GEOSoft,

Thanks for mentioning Ubound()!

Something like this ?

```Global \$a[4] = ["Ba", "Ba", "Bi", "Bi"], \$b[4] = ["Ba", "Bi", "Bi", "Bi"]
ConsoleWrite ( " : " & _IsArrayEquivalent ( \$a, \$b ) & @Crlf )

Global \$a[4] = ["Bo", "Bi", "Ba", "Bu"], \$b[4] = ["Bo", "Bi", "Ba", "Bu"]
ConsoleWrite ( " : " & _IsArrayEquivalent ( \$a, \$b ) & @Crlf )

Func _IsArrayEquivalent ( \$_Array1, \$_Array2 )
Local \$_U1 = UBound ( \$_Array1 ) -1, \$_U2 = UBound ( \$_Array2 ) -1
If \$_U2 <> \$_U1 Then Return 0
For \$_I = 0 To \$_U1
ConsoleWrite ( "-->-- \$_Array1[" & \$_I & "] : " & \$_Array1[\$_I] & " -- \$_Array2[" & \$_I & "] : " & \$_Array2[\$_I] & @Crlf )
If \$_Array1[\$_I] <> \$_Array2[\$_I] Then Return 0
Next
Return 1
EndFunc```

A small modification to wakillon's script:

```#include <Array.au3>

Global \$a[4] = ["Ba", "Ba", "Bi", "Bi"], \$b[4] = ["Ba", "Bi", "Bi", "Bi"]
ConsoleWrite ( " : " & _IsArrayEquivalent ( \$a, \$b ) & @Crlf )

Global \$a[4] = ["Bo", "Bi", "Ba", "Bu"], \$b[4] = ["Ba", "Bi", "Bo", "Bu"]
ConsoleWrite ( " : " & _IsArrayEquivalent ( \$a, \$b ) & @Crlf )

Func _IsArrayEquivalent(\$_Array1, \$_Array2)
Local \$_U1 = UBound(\$_Array1), \$_U2 =UBound( \$_Array2)
If \$_U2 <> \$_U1 Then Return 0
Local \$aT1 = \$_Array1, \$aT2 = \$_Array2
_ArraySort(\$aT1)
_ArraySort(\$aT2)
For \$_I = 0 To \$_U1 - 1
ConsoleWrite ( "-->-- \$aT1[" & \$_I & "] : " & \$aT1[\$_I] & " -- \$aT2[" & \$_I & "] : " & \$aT2[\$_I] & @Crlf )
If \$aT1[\$_I] <> \$aT2[\$_I] Then Return 0
Next
Return 1
EndFunc```

If order of the elements doesn't matter!

Au revoir,

UEZ

@Lilbert,

Depending on your actual needs, you may have to refine a bit more good UEZ code.

Do you consider equality case sensitive or not?

Do you consider elements types (i.e. does "123" equal 123)?

Thanks guys! I'll try the script and try to digest how it works. Takes some time for me to do so.

(And LOL. I should've not posted my script. Way too embarrassing for you guys to see it!)

You should have posted it, and definitely it is nothing to be embarrassed about.
