代码实现

class Solution {
    public int[] twoSum(int[] numbers, int target) {
        int left=0;
        int right=numbers.length-1;
        while(left<right)
        {
            if(numbers[left]+numbers[right]>target)
            {
                right--;
            }else if(numbers[left]+numbers[right]<target)
            {
                left++;
            }else
            {
                return new int[]{left+1,right+1};
            }
        }
        return new int[]{};
    }
}
