Out(ostream & o): out(o){}
void operator() (const T & val ) { out<<val<<" "; } };
int main() {
int t[]={8, 10, 5, 1, 4, 6, 2, 7, 9, 3};
int t1[]={1,2,3,4};
deque<int> d1(t, t+10);
set<int> s1(t, t+10);
sort(d1.begin(), d1.end());
cout<<includes(s1.begin(),s1.end(), t1,t1+4)<<" "<<includes(d1.begin(),d1.end(), t1,t1+4)
<<endl;
return 0;
}
