How to add random hyphens between letters?

[youtuber]

For example, to add random hyphens like this

w-ord

wor-d

wo-rd

d-row

dro-w

dr-ow

o-wrd...

I tried a lot but I couldn't solve the logic

Local $aWord[1] = ['word']
Local $aRandomAdd = ""
For $i = 0 To Ubound($aWord)-1
   $aRandomAdd = $aWord[$i]
   $aRandomAdd &= Random(1,StringRight($aWord[$i], $i) & "-",1)
Next
ConsoleWrite($aRandomAdd & @CRLF)

#include <array.au3>
Local $sWord = 'word'
Local $iNrWantedRandoms = 5, $iRandom, $sStrLen = StringLen($sWord)
SRandom(@MSEC)

ConsoleWrite('randomly place an hyphen' & @CRLF)
For $i = 0 To $iNrWantedRandoms
    $iRandom = Random(1, $sStrLen - 1, 1)
    ConsoleWrite(StringLeft($sWord, $iRandom) & '-' & StringRight($sWord, $sStrLen - $iRandom) & @CRLF)
Next

ConsoleWrite("randomly place an hyphen and also shuffle word's letters" & @CRLF)
Local $aWord = StringToASCIIArray($sWord)
For $i = 0 To $iNrWantedRandoms
    _ArrayShuffle($aWord)
    $sRandomWord = StringFromASCIIArray($aWord)
    $iRandom = Random(1, $sStrLen - 1, 1)
    ConsoleWrite(StringLeft($sRandomWord, $iRandom) & '-' & StringRight($sRandomWord, $sStrLen - $iRandom) & @CRLF)
Next

#include<string.au3>

$str = "word"
$insrt = "-"
$sOut = ""

for $i = 0 to stringlen($str) * 2 - 1
   $sOut &= $i < stringlen($str) ? _StringInsert($str , $insrt , random(1 , stringlen($str))) & @LF : stringreverse(_StringInsert($str , $insrt , random(1 , stringlen($str)))) & @LF
next

msgbox(0, '' , $sOut)

 

did you want them to be in unique positions.  more shuffled than random?  or really random?  and did you want the reverse strings too? 

edit:  i also assumed you didnt want the potential of a leading or trailing hyphen...

edit: also, my bad i see now they are shuffled, not just reversed.

nothing related to @youtuber request(randomness) but still....

#include <Array.au3>
#include<string.au3>

$a_String = 'word'
$a_Array = StringSplit($a_String & '-', "", $STR_NOCOUNT)
$a_suffel = _ArrayPermute($a_Array, '')
_ArrayDelete($a_suffel, 0)
_ArrayDisplay($a_suffel)
;$b_string = _ArrayToString($a_suffel)
;Msgbox(0,"", StringRegExpReplace($b_string , "\|(.*?)" , "" & @CRLF))

& not sure use of StringRegExpReplace is correct.

@jugador Thank you,That's exactly what I'm looking for. It works well for me.

@iamtheky more shuffled than random? = Yes more complicated and shuffled.

@iamtheky @Chimp Thank you. The examples are good for me, but why are sometimes similar words listed?

I think because the goal of 'random' was a misnomer.  Hyphens could all be in the same position and that position still have been randomly selected each time.

It is seeming more that you want:

1) the string shuffled

2) a random hyphen placed within the string (not before or after)

3) repeat steps 1 and 2 ensuring the results are all unique

is that accurate?  do you want the string shuffled every time around the loop?

For a complete list of all allowed results:

Local $s = "autoit"

Local $a = _ArrayPermute(StringSplit($s & '-', "", 3))
Local $b = StringSplit(StringTrimRight(StringRegExpReplace(_ArrayToString($a, ',', 1) & ',', "((?<!\w|^)-\w+,|\w+-,)", ""), 1), ',', 3)
$b = _ArrayUnique($b, 0, 0, 0, 0)
_ArrayDisplay($b)
