The algorithm returns an array of all the possible permutations (not combinations because order matters here) of x elements (x being one of the algorithm's parameters) in any given array of size n.

The maximum difference for a pair of elements in some array a is defined as the largest difference between any a[i] and a[j] where i < j and a[i] < a[j]. The declaration for a function named ...

Hi everyone,<BR><BR>Let's say I have 4 numbers: 1234.<BR><BR>I wish to find out all possible permutations of this 4 numbers. I believe there is a total of 12 permutations.<BR><BR>I couldnt figure out ...

Abstract: This paper presents a loopless algorithm to generate all permutations of a multiset. Each is obtained from its predecessor by making one transposition. It differs from previous such ...
