          Peel(potato);
                  
          Peel(carrot);
          bowl = GetBowl();
          Cut(potato);
          Cut(carrot);
          bowl.Add(carrot);

Task 2. Refactor the following if statements

Potato potato;
//... 
if (potato != null)
   if(!potato.HasNotBeenPeeled && !potato.IsRotten)
    Cook(potato);

and

if (x >= MIN_X && (x =< MAX_X && ((MAX_Y >= y && MIN_Y <= y) && !shouldNotVisitCell)))
{
   VisitCell();
}

Task 3. Refactor the following loop

int i=0;
for (i = 0; i < 100;) 
{
   if (i % 10 == 0)
   {
    Console.WriteLine(array[i]);
    if ( array[i] == expectedValue ) 
    {
       i = 666;
    }
    i++;
   }
   else
   {
        Console.WriteLine(array[i]);
    i++;
   }
}
// More code here
if (i == 666)
{
    Console.WriteLine("Value Found");
}
