class MainClass
{
   static void Main()
   {
        int value = 12345;
        Console.WriteLine(value.ToString("x"));
        
        Console.WriteLine(value.ToString("X"));
        Console.WriteLine(value.ToString("X8"));
        
        
        value = 123456789;
        Console.WriteLine(value.ToString("X"));
        Console.WriteLine(value.ToString("X2"));
