Next Permutation

Explore how to generate the next lexicographically greater permutation of an array in-place using the two-pointer technique. Understand the problem constraints and implement an efficient solution with constant extra memory in C#. This lesson helps you grasp the pattern behind next permutation problems common in coding interviews.

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] ...
