Q1) How to merge strings, each a part of the whole


Recommended Posts

Hey fellas, I got a couple questions. Hopefully someone can help me out a bit :">

Question #1:

How would I go about merging several strings? Normally the answer would be easy, but what if each of these strings is only a part of the whole and if one part of it already exists in another it should be overwritten. One could start at the beginning and cut off in the middle, another in the middle cut off at the end and one could just be the middle of the whole string. Take the following as an example.

$string1 = "1,2,3"

$string2 = "3,4,5"

$string3 = "2,3,4,5"

$string4 = "5,6,7"

therefore, the complete string is: "1,2,3,4,5,6,7"

The numbers in the string are ALWAYS in the same order, they just start and end at different places, therefore I need to merge them to get the complete string. I am puzzled at how to go about doing this :ph34r:.

Question #2

I thought I might aswell stick in another quicky question. Is there any other way than using "return" to exit a function, so the script will continue? Is using "return" the only method? I know it will work but just wanted to know if there is another way.

$STRING1 = "1,2,3"
$STRING2 = "3,4,5"
$STRING3 = "2,3,4,5"
$STRING4 = "5,6,7"

$TOTAL = $STRING1
$TOTAL = Merge($TOTAL, $STRING2)
$TOTAL = Merge($TOTAL, $STRING3)
$TOTAL = Merge($TOTAL, $STRING4)

MsgBox(0, 'test', $TOTAL)

Func Merge($TSTRING, $ISTRING)
   $START = StringInStr($TSTRING, StringLeft($ISTRING, 1)) - 1
   If $START = -1 Then $START = StringLen($TSTRING)
   $TSTRING = StringLeft($TSTRING, $START) & $ISTRING
   Return $TSTRING  
EndFunc  ;==>Merge

A "Func" ends with "Return" or when it reaches the "EndFunc" statement...

A1) You should use stringsplit to split up the items by a comma and then parse each one to see if it has been used already.

$var1 = "5,2,4,7,9"
$var2 = "7,8,6,5,2"
$var3 = "9,6,5,8,3"
$str = $var1 & "," & $var2 $ "," & $var3
$arr = StringSplit($str, ",")
$newstr = ""
for $i = 0 to $arr[0]
   if not StringInStr($newstr, $arr[$i]) Then
      $newstr = $newstr & "," & $arr[$i]
   EndIf
next

EDIT: I see I have been preceeded.
