PAT乙级一道很简答的题目，一直那不到满分，求大神指点迷津。。。

Question

我的代码：

 #include <iostream>
#include <sstream>
using namespace std;

const string mars1[14] = {"tret","jan","feb","mar","apr","may","jun","jly","aug","sep","oct","nov","dec"};
const string mars2[14] = {"tam","hel","maa","huh","tou","kes","hei","elo","syy","lok","mer","jou"};

void toMars ( string s )
{
    int n;
    stringstream ss(s);
    ss >> n;
    if ( n <= 12 )  cout << mars1[n];
    else {
        cout << mars2[n / 13 - 1] << " " << mars1[n % 13];
    }
}

void toEarth ( string s )
{
    if ( s.length() <= 3 ) {
        int flag = 1;
        for ( int i = 0; i <= 13; i++ )
            if ( mars1[i] == s ) {
                cout << i;
                flag = 0;
                break;
            }
        if ( flag )
            for ( int i = 0; i <= 11; i++ )
                if ( mars2[i] == s ) {
                    cout << i + 13;
                    break;
                }
    }
    else {
        string a, b;
        int sum = 0;
        for ( int i = 0; i < 3; i++ )   a += s[i];
        for ( int i = 4; i <= 6; i++ )  b += s[i];
        for ( int i = 0; i <= 11; i++ )
            if ( mars2[i] == a ) {
                sum += 13 * (i + 1);
                break;
            }
        for ( int i = 0; i <= 13; i++ )
            if ( mars1[i] == b ) {
                sum += i;
                break;
            }
        cout << sum;
    }
}

int main()
{
//  freopen("F://input.txt","r",stdin);
    int N;
    cin >> N;
    getchar();
    for ( int i = 0; i < N; i++ ) {
        string s;
        char ch;
        while ( ch = getchar() ) {
            if ( ch == '\n' )   break;
            else    s += ch;
        }
        if ( s[0] >= '0' && s[0] <= '9' )   toMars(s);
        else    toEarth(s);
        cout << endl;
    }
    return 0;
}

提交结果：

Answer 1

知道了= =，有两个地方错了，一个是13是个特殊值，需要加上一个判断。第二个就是当火星文处于第二个Mars数组中时，应该是(i + 1) * 13;而不是原来的
i + 13.。。
自己还是太菜了
