// use the qtcore tool to run this code

using namespace std; 
  
int main() 
{ 
  
    // declaring 
    // the string 
    QString s; 
  
    // taking input 
    // from user 
    cin >> s; 
  
    // ok: pointer 
    bool ok; 
  
    // 16 hexa base 
    int hexa_dec = s.toInt(&ok, 16); 
  
    if (!ok) { 
        // conversion not done 
        cout << "Conversion failed. Repeat conversion"
             << endl; 
    } 
    else { 
        // printing the hexadecimal value 
        cout << "your Hexadecimal conversion of given "
                "QString "
             << hexa_dec << endl; 
    } 
    return 0;
