Loop 8 characters

[deborahb44958436]

How could I loop through all possible rearrangement combinations of these 8 characters? LLLMMRRR

I need it to be output with trace command and numbered if possible.

is each L a different character?  ie, if you only had LLL would there be one or 6 displays?

[deborahb44958436]

I have 3 L's 2 M's and 3 R's in one arrangement like the one you see above.  I want them to be rearranged in deferent order and I need to see all possible combination in the output through trace command.

[kglad]

again, are different combinations that look the same, different?  if so, you'll see LLLMMRRR listed 72 times.

I want to output all possible combination since I have to go through each one by one.

[kglad]

var i:int;

var s:String = 'LLLMMRRR';

var permA:Array = [];

permF(s,'');

trace(permA);

function permF(s: String, pre: String): void {

    if(s.length < 1){

        permA.push(pre);

    } else {

        for(i = 0; i < s.length; i++){

            permF(s.substr(0, i) + s.substr(i + 1), pre + s.charAt(i));

        }

    }

}

p.s. if you want combinations (i never got an answer from you that i could understand), sort permA and loop through its elements checking for duplicates:

function removeDupsF(a:Array):Array{

    a.sort();

    for(var j:int=a.length-1;j>0;j--){

        if(a==a[j-1]){

            a.splice(j,1);

        }

    }

    return a;

}

I only get one output LLLMMRRR

[kglad]

that's interesting.  the problem is i.

use:

//var i:int; // commented out

var s:String = 'LLLMMRRR';

var permA:Array = [];

permF(s,'');

trace(permA);

function permF(s: String, pre: String): void {

    if(s.length < 1){

        permA.push(pre);

    } else {

        for(var i:int = 0; i < s.length; i++){  // <-i is local of permF and retains its value during during function calls

            permF(s.substr(0, i) + s.substr(i + 1), pre + s.charAt(i));

        }

    }

}

and please mark correct and helpful responses.  i see you still have not done that in your collision thread.

This one worked...ish, I got all the possible combinations (I think) but

they were multiplied by 72. so I got 72 LLLMMRRR and then I got

72 LLLMRMRR... and so on and so forth.
