Solution: Next Permutation

Explore how to find the next lexicographically larger permutation of an integer array using the two pointers technique. Learn to identify pivot and successor elements, perform swaps, and reverse array suffixes efficiently, all within constant space and linear time.

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  ...
