c++版：
class Solution {
private:
int low=-1;
int high=-1;
vector<int>src;
public:
vector<int> twoSum(vector<int>& numbers, int target) {
low=0;
high=numbers.size()-1;
while(low<=high)
{
int res=numbers[low]+numbers[high];
if(res>target)high--;
else if(res<target)low++;
else if(res==target)break;
}
src.push_back(low+1);
src.push_back(high+1);
return src;
}
}；
Java版:
class Solution { private int low=-1; private int high=1; private int[] src; public int[] twoSum(int[] numbers, int target) { low=0; high=numbers.length-1; while(low<=high) { int res=numbers[low]+numbers[high]; if(res>target)high--; else if(res<target)low++; else if(res==target)break; } src=new int[] {low+1,high+1}; return src; } }
