其它解法六:LeetCode 中国的普通解法,和解法二类似 class Solution: def twoSum(self, nums: List[int], target: int) -> List[int]: n = len(nums) for i in range(n): for j in range(i + 1, n): if nums[i] + nums[j] == target: return [i, j] return [] ## 找不到则返回空...
解法一实现如下: 1: vector<int>twoSum(vector<int> &numbers, int target) {2: map<int, int> mapping;3: vector<int> result;4:for(int i =0;i< numbers.size();i++)5: {6: mapping[numbers[i]]=i;7: }8:for(int i =0;i< numbers.size();i++)9: {10: int searched = target -...
