C++ 标量初始值设定项中的多余元素

Question

I have this assignment that i have to return 2 indices of the numbers in nums that add up to the int target the output is supposed to look like this: [1,2].

But in the return statement i get the error what am i doing wrong?

class Solution {
public:
    vector<int> twoSum(vector<int>& nums, int target) {
        for(int i=0;i<nums.size();i++){
            for(int j=0;i<nums.size();i++){
                if(nums[i] +nums[j]==target){
                    return new int [2]={i,j};
                }
            }
        }
    }
};

Answer 1

You choose to use vector<int> as return value, so you won't need to use new .

Remove extra things.

class Solution {
public:
    vector<int> twoSum(vector<int>& nums, int target) {
        for(int i=0;i<nums.size();i++){
            for(int j=0;i<nums.size();i++){
                if(nums[i] +nums[j]==target){
                    return {i,j};
                }
            }
        }
    }
};
