    可能有点长,不是最优解

    #include<bits/stdc++.h>
    using namespace std;
    int main(){
    	int x,y,b;
    	cin>>x>>y;
    	
    	if(y<=0 || y>12)
    	cout<<"no answer";
    	
    	if(x%400==0)
            b=1;
        else if(x%100==0)
            b=0;
    	else if(x%4==0)
            b=1;
    	else 
    	    b=0;
    	
    	if(b==1)
    	{
    		if(y==1 || y==3 || y==5 || y==7 || y==8 || y==10 ||y==12)
    		cout<<"31";
