这里运用了set
附上大佬set的用法：http://www.cnblogs.com/BeyondAnyTime/archive/2012/08/13/2636375.html

#include <iostream>  
#include <set>  
using namespace std; 
int main()  
{  
    set<int> S;  
    int m, n, a;  
    set<int>::iterator ite;  
    while(cin >> m >> n)  
    {  
        S.clear();  
        for(int i = 0; i < m; i++)  
        {  
            cin >> a;  
            S.insert(a);  
        }  
        for(int j = 0; j < n; j++)  
        {  
            cin >> a;  
            S.insert(a);  
        }  
        for(ite = S.begin(); ite != S.end(); ++ite)  
        {  
            if(ite == S.begin())  
                cout << *ite;  
            else  
                cout <<' '<< *ite;  
        }  
        cout<<endl;  
    }  
    return 0;  
}
