If you had some troubles in debugging your solution, please try to ask for help on StackOverflow, instead of here. https://leetcode.com/problems/next-permutation/description/. Here are some examples. Approach 1: Recursion . 1,2,3 → 1,3,2 Here are the steps we need to follow to solve the problem: 1 From right to left, find the first element that is violating the increase trend, this is called PartitionNumber. Intuition. Sort from the turning point to the end (A[i] to A[end]), so {3,2} becomes {2,3}. IV) Now sort all digits from position next to ‘d’ to the end of number. The replacement must be in-place and use only constant extra memory. Implement next permutation, which rearranges numbers into the lexicographically next greater permutation of numbers. Medium #32 Longest Valid Parentheses. If such arrangement is not possible, it must rearrange it as the lowest possible order (ie, sorted in ascending order). Analysis: The next permutation is lexicographically larger than the current permutation, therefore, if a sequence is monotonic decreasing, there is no way we can have a next permutation, in this case, we simply reverse the permutation, that gives a monotonically increasing sequence, which is the 1st permutation.
