Codevs1055 气球 字符串

跟学弟一起做的一个水题……
我还是好弱啊……QAQ

#include <cstdio>#include <cstring>#include <iostream>#include <cstdlib>#include <algorithm>using namespace std;const int MAXN = 101;string s[MAXN];struct QIQIU{    int num;    string ss;}Q[MAXN];bool cmp(QIQIU A,QIQIU B){    return A.num>B.num;}int main(){    int n;    cin >> n;    for(int i = 1; i <= n; ++ i)         cin >> s[i];        sort(s+1, s+n+1);    int tot = 0;    for(int i = 1; i <= n; ++ i)    {        if(s[i] != Q[tot].ss)        {            tot ++;            Q[tot].ss = s[i];            Q[tot].num = 1;        }        else Q[tot].num ++;    }    sort(Q+1, Q+tot+1, cmp);    cout << tot << endl;    for(int i = 1; i <= tot; ++ i)    {        if(Q[i].num != Q[i-1].num)            cout << Q[i].num << endl;        cout << Q[i].ss << endl;    }    return 0;}
