Grokking the Coding Interview Patterns in JavaScript

Next Permutation

Explore how to rearrange an integer array to its next lexicographically greater permutation using the two pointers technique. Understand the problem constraints and apply an in-place solution that uses constant extra memory. This lesson helps you grasp a key pattern useful for coding interviews and algorithm challenges.

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] ...
