I\'m trying to take a seven-character string and generate all the possible 3- and 4-letter permutations of it. This seems like something that recursion would 开发者_如何学运维be handy for (most all pe
I am trying to develop a program in C that will \"crack\" the crypt(3) encryptio开发者_开发百科n used by UNIX.
I want to generate a permutation of an array a and I don\'t want to use utility functions such as java.util.Collections().
I am looking for an optimal algorithm to find out remaining all possible permutation of a give开发者_Go百科 binary number.
This could be language agnostic/helpful answers could just be in pseudo-code. I have a program that I would like to test under a range of inputs. This program takes a set of files, one of which is de
I\'d like to calculate all the permutations of size Y of a set of size X.That is if I had (1,2,3) and want all permutations of size 2, 3P2, it would be (1,2) (1,3) (2,1) (2,3) (3,1) (3,2).
Let\'s say that we have two boxes of pencil开发者_如何学Cs (in first box just blue and in second just red pencils). Sothe question now is, in how many ways can we put x red and y blue pencils in the l
Alright, I know this is going to sound bad, like I\'m going to use this for un-ethical things, but you have my word that I am not.

开发者_StackOverflowCan anyone please write or give me a link where I can find the C# code to list all the permutations for a give set of numbers in the most efficient manner?Not sure how efficient th
