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" << endl;
    }
    }
}
// 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
    {
        APP::UART::send();
    }

    return 0;
}
