tricks:无序、返回下标增序、返回的是原始数组的下标。 vector<int>*pa; bool cmp(int x,int y){ return (*pa)[x]<(*pa)[y]; } class Solution { public: vector<int> twoSum(vector<int> &a, int t) { int n=a.size(); pa=&a; int* id=new int[n],i=0,j=n-1; for(i=0;i<n...
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...

std::vector<int> v; 建议使用全局的命名域方式: using namespace std; 1.vector的声明 vector<ElemType> c; 创建一个空的vector vector<ElemType> c1(c2); 创建一个vector c1,并用c2去初始化c1 vector<ElemType> c(n) ; 创建一个含有n个ElemType类型数据的vector; vector<ElemType> c(n,elem); 创建一...
