Grokking the Coding Interview Patterns in C++

Solution: Next Permutation

Understand how to solve the next permutation problem by identifying pivot and successor elements with a two-pointer approach. Learn to rearrange arrays in-place to produce the next greater lexicographical order efficiently, applying this technique to coding interviews involving 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  ...
