代码

#include<iostream>
#include<cstdio>
#include<string>
#include<map>
using namespace std;
int main(){
    map<char, int> m;
    m['A'] = 1, m['B'] = 2, m['C'] = 3, m['D'] = 4;
    int n;
    string str;
    scanf("%d", &n);
    getchar();
    for(int i = 0; i < n; i++){
        getline(cin, str);
        cout<<m[str[str.find('T') - 2]];
    }
}

还有一种更简洁的写法

#include <iostream>
using namespace std;
int main() {
    string s;
    while (cin >> s) 
        if(s.size() == 3 && s[2] == 'T') cout << s[0]-'A'+1;
    return 0;
}
