Question #1 Difficulty: 2

According to the C++23 standard, what is the output of this program? 

    #include <iostream>

template <class T> void f(T &i) { std::cout << 1; }

template <> void f(const int &i) { std::cout << 2; }

int main() {
  int i = 42;
  f(i);
}

Hint:

What exactly will be the deduced parameter type in the primary template? Is that a better or a worse match than the explicit specialization for the call f(i)?
