43. Using Namespace Directive

#include <iostream>
using namespace std;

namespace Config {
    int baudRate = 9600;
    int threshold = 50;
}
using namespace Config;
int main() {
    cout << "Baud: "<< baudRate << ", Threshold: "<< threshold << "\n";
    // your code here: add using namespace statement
    // your code here: print baudRate and threshold
    return 0;
}
