int year, month,day;
    cin >> year >>month;
    switch (month){
        case 1:day = 31; break;
        case 2:day = 28; break;
        case 3:day = 31; break;
        case 4:day = 30; break;
        case 5:day = 31; break;
        case 6:day = 30; break;
        case 7:day = 31; break;
        case 8:day = 31; break;
        case 9:day = 30; break;
        case 10:day = 31; break;
        case 11:day = 30; break;
        default: day = 31;
    }
    day = (year%4==0&&year%100!=0)||year%400==0?day+=1:day+=0;
    cout << day;
