If you're reading this, then you probably want the following four things:

1. The problem specification: gcpc-problem-2003.pdf
2. The first sample input: sample1.txt
3. The second sample input: sample2.txt
4. The test data whose output should be submitted to the judges: testdata.txt

ANSWERS TO CONTESTANT QUESTIONS

Here are the answers to all the questions I've gotten so far.

New question at 10:00am:

1. Q: If an order is given that does not affect the program does it count as a signal? For example: if they press "on" during play[.]

   A: All signals are processed, and a line is printed, even if processing the signal does not change change the state of the player.

Questions received by 9:30am:

1. Q: In the test data does the time and signal get input on one line?

   A: Yes.

2. Q: Do we "have to" use the variables "T" and "S" [...]?

   A: No. Those names were chosen in the tradition of mathematics papers, and are (as you suggest) unsuitable for programs.

3. Q: is the test data supposed to be read from the .txt file or entered manually?

   A: It does not matter. I read from the keyboard in my program and used cut/paste with my mouse.

4. Q: we would like to know how the cd data is inputted. via text box, a file, form? any of these?

   A: Students using a GUI based system may use one or more text boxes, may read from a file, or any other reasonable method they know how to use. Just don't hard-code the numbers into your program.

   This is a contest about problem solving, not parsing input.

Good Luck!
