A note on DFS/BFS runtime: Problems asked for an answer for Adj List *and* Adj Matrix. The discussion we had in class was for adjacency *lists*. Lab 6 is using an adjacency *matrix*.

Reminder:
  You may resubmit any programming assignment (i.e., A1, A2, A3, A4) within two
  weeks of when grades are released (or the day of the final exam, whichever is
  earlier) to earn back up to half of the unit test points you lost. Only unit
  test points can be earned back. When you resubmit, you must send me an email
  to let me know that you have done so.

  The two weeks counts from when grades are released on Canavs.

Next week:
    Class will be held in CF 420.
    We will spend some time working on Exercises, and some time working on Lab 7.

Coming up:
    A3 due Monday
    A4 (implementing Dijkstra; smaller than A1-3) out Monday
    A4 due a week later, Monday 5/30
    Lab 7 (implementing Huffamn Coding) out Monday, due Sunday 5/29
        Bigger than other labs, but with time to work on it in class.
