A Specialized String Theory

Test your C++ programming skills by solving the given puzzle about template specialization and overload resolution.

We'll cover the following

Puzzle code

Carefully read the code given below:

Press + to interact
#include <iostream>
template<typename T>
void serialize(T&) { std::cout << "template\n"; } 
template<>
void serialize<>(const std::string&) { std::cout << "specialization\n"; } 
void serialize(const std::string&) { std::cout << "normal function\n"; } 
int main()
{
    std::string hello_world{"Hello, world!"};
    serialize(hello_world);
    serialize(std::string{"Good bye, world!"});
}
