第四个和第五个点WA代码：

#include<bits/stdc++.h>
using namespace std;
bool l[10][10]={{0,0,0,0,0,0,0,0,0,0}
			   ,{0,0,1,0,1,0,0,0,0,0}
			   ,{0,1,0,1,0,1,0,0,0,0}
			   ,{0,0,1,0,0,0,1,0,0,0}
			   ,{0,1,0,0,0,1,0,1,0,0}
			   ,{0,0,1,0,1,0,1,0,1,0}
			   ,{0,0,0,1,0,1,0,0,0,1}
			   ,{0,0,0,0,1,0,0,0,1,0}
			   ,{0,0,0,0,0,1,0,1,0,1}
			   ,{0,0,0,0,0,0,1,0,1,0}};
int main()
{
	int a,b;
	cin>>a>>b;
	cout<<(l[a][b]?"Yes\n":"No\n");
}
