AOJ 0038 Poker Hand

こんにちは川です。

今回は問題文に書いてある通りに仕分けただけでした。

 

ソースコード

 

#include<bits/stdc++.h>

using namespace std;

int main()

{

    int num;

    while(cin>>num){

        char str;

        int hand[14]={};

        hand[num]++;

        for(int i=0;i<4;i++){

            cin>>str>>num;

            hand[num]++;

        }

        bool four=0,three=0,two[2]={};

        for(int i=1,j=0;i<14;i++){

            if(hand[i]==4)four=1;

            else if(hand[i]==3)three=1;

            else if(hand[i]==2){

                two[j]=1;

                j++;

            }

        }

        if(four)cout<<"four card"<<endl;

        else if(three&&two[0])cout<<"full house"<<endl;

        else if(three)cout<<"three card"<<endl;

        else if(two[1])cout<<"two pair"<<endl;

        else if(two[0])cout<<"one pair"<<endl;

        else{

            bool kawa=0;

            for(int i=1;i<=10;i++){

                if(hand[i]==1){

                    for(int j=0;j<5;j++){

                        if(j+i>13&&hand[1]!=1)break;

                        else if(j+i<14&&hand[i+j]!=1)break;

                        if(j==4)kawa=1;

                    }

                }

            }

            if(kawa)cout<<"straight"<<endl;

            else cout<<"null"<<endl;

        }

    }
