return new int[]{i + 1, mid + 1}；return {i + 1, mid + 1}；

leetcode167. 两数之和 II - 输入有序数组

java return
相当于声明之后就返回了
返回字符串 return new String(s);
返回数组 return new int[]{-1, -1};
C++
return {low + 1, high + 1};
应该也是返回一个数组

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

class Solution {
public:
    vector twoSum(vector& numbers, int target) {
        int low = 0, high = numbers.size() - 1;
        while (low < high) {
            int sum = numbers[low] + numbers[high];
            if (sum == target) {
                return {low + 1, high + 1};
            } else if (sum < target) {
                ++low;
            } else {
                --high;
            }
        }
        return {-1, -1};
    }
};
