Finding the n-th lexicographic permutation of a string

WebJul 11, 2024 · Let the string is called str, find the smallest index i such that all elements in str[i…end] are in descending order. If str[i…end] is the entire sequence, i.e. i == 0, then str is the highest permutation. So we simply reverse the entire string to get the smallest permutation which we consider as the next permutation. WebRearranges the elements in the range [first,last) into the previous lexicographically-ordered permutation. A permutation is each one of the N! possible arrangements the elements can take (where N is the number of elements in the range). Different permutations can be ordered according to how they compare lexicographicaly to each other; The first such …

WebSince there is only one way to order a single symbol, Perm ( 1 ) = 1 = 1!. If n > 1, an n -permutation can be constructed in two steps: first order n -1 of the symbols and then place the last symbol somewhere in the ordering. We can assume as an inductive hypothesis that there are Perm ( n -1) = ( n - 1)! ways to accomplish the first step.
