Resolve UART Namespaces

#include <iostream>
using namespace std;

// Create namespace Boot with nested namespace UART
namespace Boot{

    namespace UART {

      

            void send(void) {cout << "BOOT UART";}


    }

}
// Create namespace App  with nested namespace UART
namespace App{

    namespace UART {

      

            void send(void) {cout << "APP UART";}


    }

}

int main() {
    int mode;
    cin >> mode;

    // Call correct send() function here
    if(mode == 1) Boot::UART::send();
    else if(mode ==2) App::UART::send();

    return 0;
}
