类似于 binary search

public class Solution {
    public int[] twoSum(int[] numbers, int target) {
        int[] result = new int[2];
        int start = 0;
        int end = numbers.length - 1;
        while (start < end) {
            if (numbers[start] + numbers[end] == target) {
                result[0] = start + 1;
                result[1] = end + 1;
                break;
            } else if (numbers[start] + numbers[end] > target) {
                end--;
            } else {
                start++;
            }
        }
        return result;
    }
}
