Python like join with C++ variadic templates

variadic_join.cc

// Compile and run with g++ -o vjoin --std=c++17 variadic_join.cc; ./vjoin
// c++17 standard might not be needed since we use the c++11 variadic template notation
#include <bits/stdc++.h>
using namespace std;
using ll = long long;

template<typename T>
void join(stringstream &ss, const string &sep, T t) {
    ss << t;
}

template<typename T, typename... Rest>
void join(stringstream &ss, const string &sep, T first, Rest... rest) {
    ss << first << sep;
    join(ss, sep, rest...);
}

int main() {
    stringstream ss;
    join(ss, ", ", "abbasd", 12, "cdsddsd", 13.1);
    cout << ss.str() << endl;
    return 0;
}
