# next permutation solution

If not exist, this is the last permutation. This problem is similar of finding the next greater element, we just have to make sure that it is greater lexicographic-ally. If such arrangement is not possible, it must rearrange it as the lowest possible order (ie, sorted in ascending order). From the wikipedia, one classic algorithm to generate next permutation is: Step 1: Find the largest index k, such that A[k]A[k]. DO READ the post and comments firstly. Next Permutation. Here are some examples. When we order numbers we want to "increase them by the smallest amount". A permutation is each one of the N! Implement next permutation, which rearranges numbers into the lexicographically next greater permutation of numbers. LeetCode â Next Permutation (Java) Implement next permutation, which rearranges numbers into the lexicographically next greater permutation of numbers. Problem: Implement next permutation, which rearranges numbers into the lexicographically next greater permutation of numbers.. (in this problem just sort the vector and return.) they're used to gather information about the pages you visit and how many clicks you need to accomplish a task.
