Solution:

class Solution {
public:
    vector<int> twoSum(vector<int>& numbers, int target) {
        int le = 0;
        int ri = numbers.size()-1;
        vector<int> result(0);
        while(true)
        {
            if(numbers[le] + numbers[ri] > target)
            {
                ri--;
            }else if(numbers[le] + numbers[ri] < target){
                le++;
            }else if(numbers[le] + numbers[ri] == target)
            {
                result.push_back(le+1);
                result.push_back(ri+1);
                break;
            }
