Implement next permutation, which rearranges numbers into the lexicographically next greater permutation of numbers. • If such an arrangement is not possible, it must rearrange it as the lowest possible order (i.e., sorted in ascending order). • The replacement must be in place and use only constant extra memory. • • Example 1: • Input: nums = [1,2,3] • Output: [1,3,2] • Example 2: • Input: nums = [3,2,1] • Output: [1,2,3] • Example 3: • Input: nums = [1,1,5] • Output: [1,5,1] • Example 4: • Input: nums = [1] • Output: [1] • Link to challenge: https://leetcode.com/explore/featured... • OR • https://leetcode.com/problems/next-pe...
