Which of these loops can be easily rewritten as an enhanced for loop?

1. Yes|No

   for (i = 0; i < values.length; i++)
   {
      if (values[i] == 0)
      {
         count++;
      }
   }
   

2. Yes|No

   int sum = 0;
   for (i = 1; i < values.length; i++)
   {
      if (values[i - 1] > values[i])
      {
         sum = sum + values[i]
      }
   }
   

   It possible to write this as an enhanced for loop (try it—you need another variable to remember the previous value), but Sara says it isn't easy. If it's easy for you, great!
3. Yes|No

   for (i = 0; i < values.length; i++)
   {
      values[i] = i * i;
   }
   

   You can not modify array values in an enhanced for loop.
