京东笔试题—集合问题
本地编译结果正确，在网上却说编译结果错误；求大牛看看哪有问题
#include<set>
#include<iostream>
using namespace std;
int main()
{
set<int>set1;
int n,m,a,b;
cin>>n>>m;
for(int i =0;i<n;i++)
{
cin>>a;
set1.insert(a);
}
for(int j=0;j<m;j++)
{
cin>>b;
set1.insert(b);
}
set<int>::iterator set1_iter;
for(set1_iter = set1.begin();set1_iter != set1.end();set1_iter++)
{
cout<<*set1_iter<<" ";
}
cout<<endl;
}
