int isLeap(int year)
{
    if(year%4==0&&year%100!=0||year%400==0)
    return 1;
    else
    return 0;;
}
int main() {
    int year,month;
    int day[12] = {31,28,31,30,31,30,31,31,30,31,30,31};
    while(scanf("%d %d\n",&year,&month)!=EOF)
    {
        if(isLeap(year)&&month==2)
        printf("29\n");
        else
        printf("%d\n",day[month-1]);
    }
}

1.对闰年下的2月做特殊处理，其他情况直接存储对应天数
