![]() Example 1: Input: nums 1,2,3 Output: 1,2. Vfirst.insert(vfirst.begin(),nums) //vector_name. Permutations Given a collection of distinct integers, return all possible permutations. Given an array nums of distinct integers, return all the possible permutations.You can return the answer in any order. This is a solution that I have trouble understanding, I wrote comments with questions.įor(int i = 0 i v(nums.begin(),nums.end()) Īuto res = permute(v) //Why does permute(v) work here if our function is inside permute? Since permute is a vector of a vector does that mean permute(v) will make res a vector of a vector only containing the current v value, (in which v is a value of nums where 1 element is removed)?įor(int j = 0 j vfirst = res //don't understand Leetcode Patterns Table of Contents Background Fundamentals Notes Question List Solutions Suggestions Acknowledgements Background This repo is intended for any individual wanting to improve their problem solving skills for software engineering interviews. You can return the answer in any order (C++). As the name of the problem suggests, this problem is an extension of the Permutation problem.
