int n, a, b, c, maX;
string s;
string A="ABC";
string B="BABC";
string C="CCAABB";

int main(){
 while(A.size()<=100) A+=A;
 while(B.size()<=100) B+=B;
 while(C.size()<=100) C+=C;
 
 cin >> n >> s;
 
 for(int i=0; i<n; i++){
  if (s[i]==A[i]) a++;
  if (s[i]==B[i]) b++;
  if (s[i]==C[i]) c++;
  maX= max( max(a,b), c );
 }
 
 cout<<maX<<"\n";
 if (a==maX) cout<<"Adrian\n";
 if (b==maX) cout<<"Bruno\n";
 if (c==maX) cout<<"Goran";
}
