leetcode.com 题目描述 Given an array of integers, return indices of the two numbers such that they add up to a specific target. You may assume that each input would have *exactly* one solution, and you may not use the *same* element twice. Example: Given nums = [2, 7, 11, 15]...
class Solution { public: vector<int> twoSum(vector<int>& nums, int target) {vector<int> result; std::multimap <int, int> value; std::vector<int>::const_iterator cit = nums.begin();int index =0; for (; cit != nums.end() ; index++, cit++) {...
因此我们可以用两个for循环遍历整个数组,找到这个数组中两个值的和等于这个给定值的数组下标并输出。 回到顶部 三、Go代码 //1_常规解法func twoSum(nums []int, targetint) []int{varresult = [2]int{0,0}iflen(nums) <2{returnnil }fori :=0; i < len(nums) -1; i++{forj := i +1; j...
