Solution: Next Permutation

Explore how to efficiently rearrange an array to its next lexicographically greater permutation using a two pointers technique. Understand how to identify the pivot and successor elements, perform swaps, and reverse the suffix to achieve the next permutation in-place within constant memory.

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  ...
