I don't know how this did happen... It's the first time I've been encountered with such a trouble... Everything seems to be correct, all "home" tests having passed, but... WA2
Somebody, please help me!

My code:
#include <cstdio>
#include <algorithm>
using namespace std;

struct Card
{
    int value;
    char color;
    Card(int value = 0, char color = 0) : value(value), color(color) {}
    bool in()
    {
        char c;
        while(1)
        {
            c = getchar();
            if(c == EOF)
                return false;
            if((c >= '1') && (c <= '9'))
                break;
            if(c == 'A' || c == 'J' || c == 'Q' || c == 'K')
                break;
            if(c >= 'A' && c <= 'Z')
                for(;;);
            if(c >= 'a' && c <= 'z')
                for(;;);
            if(c == '0')
                for(;;);
        }
        switch(c)
        {
            case '1':
                value = 10;
                getchar();
                break;
            case 'J':
                value = 11;
                break;
            case 'Q':
                value = 12;
                break;
            case 'K':
                value = 13;
                break;
            case 'A':
                value = 14;
                break;
            default:
                if(c < '1' || c > '9')
                    for(;;);
                value = c - '0';
        }
        color = getchar();
        if(!(color == 'H' || color == 'D' || color == 'S' || color == 'C'))
            for(;;);
        if(value < 1 || value > 14)
            for(;;);
