Ah, I see now.

Quote:

The next k lines each contain a single character, followed by a space, followed by the binary sequence (of length at most 10) representing the associated code of that character.

However, some of the input files contain as many as 20 digits in the code for a single character. UWaterloo has some explaining to do!

does anyone know how the scoring works?

i tested my programs and for J4/J5, only some of the cases worked

Each question is worth a maximum of 15 points, making your total mark out of 75.

Depending on how many test cases there are, you'll get X number of points for correct output on a test case. For example, J4 has 5 test cases, thus making each correct test case worth 3 points.

wait but then each test case has multiple parts, what if i all but one of the parts, how do part marks work?

You should probably go ask your teacher.

[Insectoid]

You get 1 mark for each test case. I don't know if part-marks exist. From what I saw (mine was marked in front of me), it's a right/wrong situation. Perfect output? 1 mark. Small mistake? 0.

Yeah exactly. I'm going to complain to my teacher to get her to complain to the organizers . Its odd they didn't catch such a big mistake...

what about the ones that make you continue until a stop sequence is entered?

AFAIK most judging uses diff, so its most likely that points are still all or nothing in that case. As for each test case being worth 1 mark, thats incorrect as there are variable numbers of test cases, and yet each problem is still worth 15 marks.

So I think I got questions S1-4, but only just got past parsing the input on S5 before running out of time, so I just outputted the hard-coded number 42. Maybe I'll get lucky and get a point or two on it . I don't know when my teacher will be marking it though. I hope to see some of you guys at stage 2, if I get in.

And yeah, if it's like past contests, each test case is worth a different number of points. Also for test cases with multiple parts, I think you need to get them all right to get the points.

No, you won't? I'm pretty sure Waterloo checks for these.

[Insectoid]

Waterloo will check it, your teacher won't. Marks are based purely on the output; the teacher doesn't even have to look at the code. If you do well and your teacher sends your code in to waterloo, THEN they will check it over.

the test cases have been released go check http://access.mmhs.ca/ccc/index.htm

I thought of a really clever way to parse s5 input in python, that I'll post if I'm allowed to yet.

I'm sure lots of people thought of it though.

im pretty sure youre allowed to, since answers for J1-J4 have already been posted in the above link
