Resolve UART Namespaces

#include <iostream>
using namespace std;

// Create namespace Boot with nested namespace UART
namespace Boot{
    void send(){
        cout<<"BOOT UART";
    };
}

// Create namespace App  with nested namespace UART
namespace App{
    void send(){
        cout<<"APP UART";
    }
}

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

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

    return 0;
}
