力扣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<int> twoSum(vector<int>& 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}; } };
