Grokking the Coding Interview Patterns in Python

Next Permutation

Explore how to find the next lexicographically greater permutation of an array by applying a two-pointer technique. Understand in-place rearrangement strategies and improve your problem-solving skills for coding interviews focused on array manipulation.

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] ...
