I have got right answers for all the test cases in Udebug and for the test cases in the forum! still getting a WA ! anybody could help please?

Hi all I got the right answers on all test cases posted here and the ones in uDebug, however my code got WA many times.

After looking at the code found the issue, and it was on the case that a suit did not had any cards.
So if you have issues after passing all test cases posted here and in uDebug look at this case.

I keep getting WA here, however I passed all the tests on uDebug. Here's my code (c++11):

Code: Select all

#include<iostream>
#include<vector>
#include<unordered_map>   
#include<sstream> //stringstreams
using namespace std;

enum class Suit {
    spades='S',hearts='H',diamonds='D',clubs='C'
};

const array<Suit,4> all_suits = {Suit::spades, Suit::hearts, Suit::diamonds, Suit::clubs};

istream& operator>>(istream& is, Suit& s) {
    char c = is.get();
    switch(c) {
        case 'S': s = Suit::spades; break;
        case 'H': s = Suit::hearts; break;
        case 'D': s = Suit::diamonds; break;
        case 'C': s = Suit::clubs; break;
        default: is.setstate(ios_base::failbit);
    } 
    return is;
}

string operator+(const char* s, const Suit& suit) {
    string str(s);
    return str + static_cast<char>(suit);
}

ostream& operator<<(ostream& os, const Suit& suit) {
    return os << static_cast<char>(suit);
}

struct Card {
    char value;
    Suit suit;
