Solution: Next Permutation

Explore how to rearrange an array of integers to the next lexicographically greater permutation using a two pointers approach. Understand the method to find the pivot and successor elements, perform swaps, and reverse the suffix to achieve the next permutation efficiently and in-place. This lesson helps you apply the two pointers technique to solve permutation problems with optimal time and space complexity.

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  ...
