CS21 Week6 In-Class Exercises

1. We are going to continue with last week's in-class assignment. If you have not already done so, create a week5 subdirectory and copy over my starting point files:

   % cd  
   % cd cs21
   % mkdir week5
   % cd week5
   % pwd 
   % cp ~newhall/public/cs21/week5/* .   
   

   We will continue with the TODO parts of this assignment.

   In addition we will add the following part if we have time:

           // TODO: write a method TopThree, that takes the grades array
           //       and its effective size, and returns an array with three
           //       buckets containing the three largest grades in the grades
           //       array.  If the grades array has fewer than 3 grades, then
           //       your returned array should have -1s in any buckets that 
           //       are invalid.  The method should also return null on an
           //       error.
           //
           //       Call this method with your grades array and print out
           //       the resulting top 3 grades.
