#include <iostream>
using namespace std;
int main()
{
    int a,b;
    cin >> a >> b;
    int sum = 0;
    int flag = 1;
    while(1)
    {
        if(a == b&&flag == 1)
        {
            cout << "O JOGO DUROU 24 HORA(S)";
            break;
        }
        flag = 0;
        if(a == b&&flag == 0)
        {
            cout << "O JOGO DUROU "<< sum << " HORA(S)";
            break;

        }

        a++;
        sum+=1;
        if(a >= 24)
            a%=24;

    }
    return 0;
}

光用if好像还简单点
