vector<int> twoSum(vector<int>& nums,inttarget) { } }; 为了测试&标识符的作用,测试程序如下所示,其中test1函数没有加&标识符,test2函数加了&标识符。 #include <iostream>#include<vector>usingnamespacestd;voidtest1(vector<int>a) { a[0] =4; }voidtest2(vector<int>&a) { a[0] =4; }void...
方法一:暴力枚举 classSolution{public:vector<int>twoSum(vector<int>& nums,inttarget){intn = nums.size();for(inti =0; i < n; ++i) {for(intj = i +1; j < n; ++j) {if(nums[i] + nums[j] == target) {return{i, j}; } } }return{}; } }; 方法二:哈希表 classSolution{pu...
定义一名为vectortwoSum的函数,(若你前面没定义返回值,缺省为int)它有两个参数 一是vector的引用 二是一个整形 个人建议,初学者先看教程上的语法(必须牢记),然后自己写程序,,而不是去研究别人的程序,这个对你学习没有帮助的
vector< vector< int> >v; 二维向量//这里最外的<>要有空格。否则在比较旧的编译器下无法通过 实例 1.pop_back()&push_back(elem)实例在容器最后移除和插入数据 实例 #include <string.h> #include <vector> #include <iostream> using namespace std; int main() { vector<int> obj; //创建一个向量...
Given a finite setX of vectors from the unit ball of the max norm in the twodimensional space whose sum is zero, it is always possible to writeX = {x1, , xn} in such a way that the first coordinates of each partial sum lie in [–1, 1] and the second coordinates lie in [–C...

收获: vector<vector<int> >res,不能直接用res[j].push_back(number),因为res[j]是空的,没有初始化 可以先定义 vector<int> inNumer, res.push_back(inNumber)即可。 Tw
