Next Permutation

Explore how to rearrange an array to its next lexicographically greater permutation by applying the two pointers technique. Understand the constraints of in-place modification using constant extra memory while handling edge cases like the highest permutation order. This lesson helps you implement and grasp this pattern efficiently.

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] ...
