WebMay 27, 2010 · To generate next permutation you are trying to find the first index from the bottom where sequence fails to be descending, and improves value in that index while switching order of the rest of the tail from descending to ascending in this case. Here is the core of the algorithm: //ind is an array of integers for(int tail = ind.length - 1;tail ... WebJul 24, 2015 · Let us call the set of all the outcomes as the permutation set, and each permutation outcome as the permutation number. Each permutation number consists of 4 digits, chosen from the ${a,b,c,d}$. Each permutation number in this set is mapped to a number between $0$ to $23$.

WebA simple solution would be to use std::next_permutation that generates the next greater lexicographic permutation of a string. If the function can determine the next higher permutation, it rearranges the elements and returns true. If that was not possible (because it is already at the largest possible permutation), it rearranges the elements ...
