用多边形外角来做,外角和为360度,然后比对边数

 1 #include <iostream>
 2 using namespace std;
 3 
 4 int t,a;
 5 
 6 int main()
 7 {
 8     ios::sync_with_stdio(false);
 9     cin>>t;
10     while(t--)
11     {
12         cin>>a;
13         int n;
14         n=360/(180-a);
15         int sum;
16         sum=(n-2)*180;
17         if(n==sum/a) cout<<"YES"<<endl;
18         else cout<<"NO"<<endl;
19     }

21 }
