Please help me with the task: LearningConst.BrokenVirus

Hello, I’m working on this task:

This virus doesn’t seem to compile correctly. Fix it! (If you change any string constants, the virus becomes useless.)

Here is my code:


namespace LearningConst
{
   class BrokenVirus
   {
       static void Main(string[] args)
       {
           Console.WriteLine("Checking self destruction options.");
           const string input = Console.ReadLine();
           
           if (input == "available")
           {
               Console.WriteLine("Start self destruction. RIP, machine.");
           }
           else
           {
               Console.WriteLine("Turning off.");
           }
       }
   }
}

Can anyone please help me to solve it?
