What does this C++ snippet output?

1#include <iostream>
2#include <string>
3struct A { virtual ~A() {} virtual std::string t() { return "A"; } };
4struct B : A { std::string t() override { return "B"; } };
5int main() {
6    A* p = new B();
7    std::cout << (dynamic_cast<B*>(p) != nullptr) << " "
8              << (dynamic_cast<A*>(p) != nullptr) << "\n";
9    delete p;
10}
