Next Permutation

Explore how to rearrange an array into its next lexicographically greater permutation using the two pointers method. Understand how to handle cases where no higher permutation exists by resetting the array to the lowest order. This lesson helps you implement an efficient in-place solution with minimal 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 [4,5,6][4, 5, 6], the next permutation is [4,6,5][4, 6, 5] ...
