Explore how to rearrange an array to its next lexicographically greater permutation using the two pointers technique. This lesson guides you through finding pivot and successor elements, swapping them, and reversing the suffix in-place to achieve the next permutation efficiently in Go.

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..
