Solution: Next Permutation

Explore how to find the next lexicographically greater permutation of an integer array using the two pointers technique. Understand how to identify the pivot and successor elements, swap them, and reverse the suffix to achieve the smallest next permutation. This lesson helps you implement an efficient in-place algorithm with O(n) time and O(1) space complexity.

We'll cover the following...

Statement

Your task is to rearrange an array, nums, containing positive integers to form the next lexicographically greater permutationA permutation of an array of integers refers to any ordering of its elements into a sequence or linear arrangement.. This means finding the next permutation in the sequence of all possible arrangements sorted in dictionary order.

For example, given the array  ...
