### 2004.06.21: Mini-contest: Data structures

We had our first mini-contest today, with problems 262 and 330 from http://acm.uva.es/problemset/ . It took us half an hour to set up PC^2, which I configured for Java use. Mark Punzalan successfully solved problem 262 (Transferable Voting) after a few runs that had problems with spoiled ballots. A number of other people attempted a few submissions, but no one else succeeded.

If you study the sample solutions, you can see:

- How input/output is generally handled
- A particular (but not necessarily the best) algorithm for solving the problem
- How ugly code can get when written under time pressure ;)

The sample solution may not address all test cases. Oh well. =)
