Discussion on C++ Class Templates Challenge

7 years ago+ 1 comment

Both my code and the top two codes in discussions are terminated due to timeout. I don't know how to reduce the runtime anymore. Could anyone successfully solving this problem point out the pitfalls in my code? The version 1 of the following code is my code. The version 2 is quoted from Discussions.

// Version 1 - Phoenix(me)

template<class T>
class AddElements {
    T e1;
public:
    AddElements (T arg) {e1=arg;}
    T add (T e2) {return e1 + e2;}
};

template <>
class AddElements<string>{
	string e1; 
public:
	AddElements (string str){e1 = str;}
	string concatenate(string e2){return e1 + e2;}    
};

// Version 2 - kk65g3

template <class T> class AddElements {
public:
	T element;
	AddElements(T i) {element = i;}
	T add(T i) {return element+i;}
private:
};

template <> class AddElements <string> {
public:
	string element;
	AddElements(string i) {element = i;}
	string concatenate(string element2) {return element+element2;}
private:
};

use C++ instead of C++14; otherwise, run the following before main using global variable + class constructor:

ios_base::sync_with_stdio(false); cin.tie(NULL);

The timeout error makes me confused whether my code is right.Thanks for your advice that uses c++ instead of c++14,but I still want to know why?Is it the compiler problem?
