I think I know the culprit. The story I was told is that the person precomputed some of the results and submitted a huge source file (in tens of megabytes) of hard coded data. This probably led to subsequent amendment of the rules regarding source file sizes.

I'll report back once I find the persons involved.

Wasn't this for one of the questions on the second day? Where you had to submit a series of outputs, but these were trivial to generate once you cracked the problem.

I remember getting an "aha" moment, writing a program, and then submitting (scored 100% too!). Then, I met a guy who also cracked the problem and realized that he just needed to paste the test data into a spreadsheet, do some basic sorting there, and then paste the output into a text file; no coding necessary.

I felt pretty stupid afterwards.

I think you're referring to "double crypt" of the day 2 problem set. For this problem you submit the result/answer instead of the code, so it shouldn't trigger a compilation/source code limit.
