ActionScript 2.0 :: Permutations / Combinations Of Letters In A String
Jul 30, 2010
I've searched high and low for a simple function that gives me all the possible combination of a set of characters with no avail. Anyone here got enough of a maths brain for this one? I want a function around the likes of this: possibleCombinations("abc"); which returns an array: "abc", "ab", "a", "cba", "cb", "c", "..." ETC You'd be doing me a hug favor as a deadline depends in the delivery of this code.

Algorithm to generate all possible letter combinations of given string down to 2 letters
Trying to create an Anagram solver in AS3, such as this one found here:
[URL]
I'm having a problem wrapping my brain around generating all possible letter combinations for the various lengths of strings. If I was only generating permutations for a fixed length, it wouldn't be such a problem for me... but I'm looking to reduce the length of the string and obtain all the possible permutations from the original set of letters for a string with a max length smaller than the original string. For example, say I want a string length of 2, yet I have a 3 letter string of "abc", the output would be: ab ac ba bc ca cb.
Ideally the algorithm would produce a complete list of possible combinations starting with the original string length, down to the smallest string length of 2. I have a feeling there is probably a small recursive algorithm to do this, but can't wrap my brain around it. I'm working in AS3.

Good technigue for finding out if a string has any letters?I'm not looking for a specific letter, I just want to search a string and find out if it has any letters.

For a rather complex search function I need to get the first letter of each word entered into an input field. At first glance this may not seem like a big problem if every word is neatly seperated by a space.
Although people can enter whatever they want into the field I only want to work with the words that start with a-z or A-Z.
I'm having a bit of trouble figuring out how I can determine if a character in the string falls into this selection. One of the possibilities is to use charCodeAt(), but that's rather rough. I can walk through the string using indexOf() but I may have trouble finding the next word if characters other than a space come into play.

Is there a way to take all the letters out of a string and then use it as a integer?If that is not possible, is there a way to take the first three letters off a string variable? i.e. make myVariable='pic1' into myVariable = '1' Yes? no?

I've made some code that loads a line from a text file as a string and puts it into a dynamic field. What I want to do is randomize the letters of the string, but I can't seem to find any functions that do so. Anyone have an idea as to how you do this?
Code:
var url:String = "test.txt";
var loader:URLLoader = new URLLoader();

I'm using the following code:[code]The textFeild shows nothing (the textField is coded correctly, as it shows regular strings).However, the trace shows it as:[code]I've got the textfield set large enough to accomodate the text.Is there a better way to split a string into individual letters, and then display them in a field one above the other?

I'm using an "input array" to receive keyboard input from the user (keyboard events tag the character code in an array, and during input check phase, the procedure checks specific cells in the arrays).In my case, it works properly, but different key combinations don't work together![code]all combinations work together, besides when KEY_UP and KEY_CCW are pressed together (the one which was pressed before only responds) and the KEY_DOWN and KEY_CW combination. Anyone has a clue what's wrong?

Does flash have some key combinations reserved? I am creating keyboard shortcuts and am discovering that some of the key combinations do not work. For example, Control + H does not work, but if I switch it to Control + L it works fine. I've found a few other Control + (letter) that do not work either. Is there a way to disable whatever flash has reserved so I can use whatever letter I want?

does anybody know an algorithm which calculates and returns all the possible combinations (NOT permutation) of the elements of an array?Here an example of what I need:
Code:
var arr:Array = [a, b, c, d]
var combinations:Array = [[a,b],[a,c],[a,d],[b,c],[b,d],[c,d],[a,b,c],[a,b,d],[b,c,d],[a,b,c,d]] //surely I have missed some combination...

I'm revisiting some old code that filters XML, but this could easily apply to the parameters of a method (the way I'm using it, it essentially is). This is a problem I feel like I run into a lot and don't know a good way around this. So the problem is that I've got 3 arguments. They're all optional. I want to see which ones are presents and test if their values based on which ones are present (sorted according to likelihood):

I'm trying to find a way to add to the front and back of a word in a string based on the letters it starts with.
For example if I had a string "I think http://www.facebook.com/ is better than http://twitter.com" it would look for the instance of "http://" and give me "I think <b>http://www.facebook.com/</b> is better than <b>http://twitter.com</b>"

I'm starting using the CS4 version of flash, and in my codes, every word is "missing" the last letter. It's not really missing, we just can't see it, or see only half of it. Did it ever happen to you? If so, how can I fix this?

I know how to catch usual lowercase letters. I'm using KeyboardEvent.KEY_DOWN and compare the code to the ASCII table to find out which key was pressed. Now, I also want to be able to find out if there is, for example SHIFT+A pressed, and I have no idea how to implement this. I mean, in my program SHIFT and A are absolutely different keys which have nothing to do with each other, and they both will call KeyboardEvents when pressed. In Georgian alphabet some letters are typed by combination of SHIFT and English letters, for example W on Georgian keyboard means წ, when SIFT+W means áƒ. Absolutely different letters, as you can see. And I want to be able to catch both, coz I'm currently developing Georgian-language game.
