Next Permutation

Explore how to rearrange an array to the next lexicographically greater permutation using the two pointers technique. Understand when to reset to the smallest order and implement the solution efficiently with constant extra 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] ...
