解题思路：对每个字符串都扫一遍，如果有CD那么赢的场数减一。

代码：

#include<iostream>

#include<string>

#include<cstring>

using namespace std;

char str[1005];

int Judge()

{

    int i;

    for(i=0;i<strlen(str)-1;i++)

    {

        if((str[i]=='C')&&(str[i+1]=='D'))

            return 1;

    }

    return 0;

}

int main()

{

    int N;

    while(cin>>N)

    {

        int sum=N;

        while(N--)

        {

            cin>>str;

            if(Judge())

                sum--;

        }

        cout<<sum<<endl;

    }

    return 0;

}
