CCC Prep -- '98

-----------------------------------

This year's CCC is looming near, and what better way to prepare than reviewing previous years' CCC's? :) I'll just post the questions to 1998's senior contest, and let's try to get together a large selection of different solutions. Remember, the CCC allows any language to be used, so if you consider a question to be relatively simple, or you've done it before, challenge yourself by doing it in a language you're still just learning.

[url=http://contest-cemc.uwaterloo.ca/ccc/1998/1a-prob.html]Problem 1 -- Censors
[url=http://contest-cemc.uwaterloo.ca/ccc/1998/1b-prob.html]Problem 2 -- Cross-Number Puzzle
[url=http://contest-cemc.uwaterloo.ca/ccc/1998/1c-prob.html]Problem 3 -- Mars Rover
[url=http://contest-cemc.uwaterloo.ca/ccc/1998/1d-prob.html]Problem 4 -- Lottery
