I would like to have a javascript that calculates all possible letter combinations of given letters with number of characters in the output.
However, not the same letter from the given letters more than once, except it is in the given word more than once.
For example:
- Named letters "ABCDE"
- Output letters are 4
- Results could be OKAY: "CBED", "ACED", "DEAB", "BCDE" etc
- But NOT OKAY: "AABC" or "BCCC"
However, if
- Named letters "ABCCD"
- Output letters are 4
- Results could be OKAY: "CBEC", "ACCD", "DABC", "ABCC" etc
- But NOT OKAY (more than 2 C's, as it is in the given word): "AABC" or "BCCC"

the number of possibilities is given by Permutation.
for the implementation I’d use an array and lots of loops.
note however, that the number of your results get soon very big (5 out of 10 is already > 30,000; 10 out of 20 is > 670,000,000,000 ).
Thanks Dormilich for your reply

Hi all. I have a rather short question:
How can I in xsl to get a letter, given its position
in the alphabet, e.g. given number 5, return a letter 'e'?
Is it possible in pure xsl or do I need to use java extension?
Thank you very much for help.

I am looking at creating list of letter combinations.
letters a-h
6 letters per combination
letter can repeat its self in the combination, but not next to its self
and, a series of letter can not repeat in the combinations.
So, ababab, abcabc would not be alowed but, abcbca, abcbac... would all be
alowed.

Thanks to James A. Fortune in this Newsgroups "Creating random letter
combinations", I execute the code he proposes and there were 500,000
combinations generated. This is more than we need to give passwords to our
students.
But then, I realized that there were many duplicates.
Somebody can give me the code to avoid the duplicates? Or a query to delete
the duplicates in the tblOutput?

Hi,
I want to identify combinations of letters (a-z)... to make the combination
unique, but where the order of these letters is not important.
For example:
'er' and 're' should have the same unique identity.

Hi everybody!
I am just at the beginning as a programmer, so maybe this is a stupid
question...Anyway,I need to write a function in C to generate generate
all possible strings of given length given a set of characters
(allowing repetitions of the same character)
For example given the characters 'E' and 'H' and maximum length 3 the
function should generate the sequences

I haven't let it run to completion, but how about below; it uses a
char rather than lots of strings to save the GC some work... it only
goes 5 levels deep on the stack, so shouldn't blow up...

char data = new char;
Loop(data, 0);

Hello,
I am writing a "scrabble code" on Python. I have some problem with getting possible words from the given letters. For example:
Given letters are: 'c', 'r', 'n', '*'
Here '*' can be any letter.
Possible words: 'cry', 'corn', 'run', etc.
proper_word_list is a file containing all the english words.
score_of_word is a function that computes the score of the word.
hand is the letters that are given to the player

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...
