4. Complete the Markov Team/Partner evaluation on ANGEL (in the Assignments folder).
5. Do the following written problems.  You can write them by hand, or do them on your computer and  print them out.  Bring a printed copy to the Day 27 class.

1. (15 points) Weiss exercise 6.2. You can just write the code for part (a) out by hand if you wish, but I recommend getting it working in Eclipse and printing out your code.  Here is some code that you can use to test your method if you wish:

public static void main(String[] args) {
  Collection<Collection<String>> a = new ArrayList<Collection<String>>();

  String[][] arrays = {{"abc", "def", "ghi"},
                       {"xyz", "uvw", "abc", "abc"},
                       {"a", "ab", "abc", "xyz", "abc"}};

  for (String[] sArray : arrays){
    Collection<String> a1 = new ArrayList<String>();
    for (String s: sArray)
      a1.add(s);
    a.add(a1);
  }
  System.out.println(count(a, "abc"));
}

2. (5 points) Weiss exercise 6.4.
