力扣第一题（两数之和）完整代码

方法1

#include 
#include 
using namespace std;

class Solution {

public:
   vector twoSum(vector& nums,int target)
	{
		vector ans;
		for(int i=0;i ans;
	int target=9;
	vector nums={2,7,11,17};

	ans=sol.twoSum(nums,target);
	 for (auto i:ans)
        cout << i << endl;
	return 0;
}
