[email protected] 大佬求个 lifetime!

```cpp
#include <iostream>

struct Base {
void print() {
std::cout << "Base class\n";
}
};

struct Str : Base {
Str(const char* s) {}
void print() {
std::cout << "String class\n";
}
};

struct Num : Base {
Num(int v) {}
void print() {
std::cout << "Number class\n";
}
};

template<typename T>
struct Mapper;

template<>
struct Mapper<const char*> {
using type = Str;
};

template<>
struct Mapper<int> {
using type = Num;
};

template<typename T>
void log(T obj) {
typename Mapper<T>::type mappedObj(obj);
mappedObj.print();
}

int main() {
log("hello");
log(123);
}
```

请问有应届的招聘吗
