Grokking the Coding Interview Patterns in Go

Next Permutation

Explore how to rearrange an array to its next lexicographical permutation using efficient two pointers techniques in Go. Learn to implement this in-place solution with constant extra memory, understand edge cases, and practice your skills in a coding playground.

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] ...
