华为机试-字符串排序

直接使用c++11 multiset存输入字符串，自动排序

#include<iostream>
#include<set>
#include<string>
using namespace std;
int main()
{
    multiset<string> ms;
    int num = 0;
    string str = "";
    cin >> num;
    while (num)
    {
        --num;
        cin >> str;
        ms.insert(str);
    }
    for (multiset<string>::iterator it=ms.begin();it!=ms.end();++it)
    {
        cout << *it<<endl;
    }    
}
