Next Permutation

Explore the next permutation problem to understand how to rearrange arrays into the next lexicographically greater order. Learn to apply the two pointers technique to solve this in-place using constant memory. This lesson helps you master efficient array manipulation crucial for coding interviews.

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] ...
