Canadian Computing Competition
(Last modified Monday March 13, 2006)

This provides ALL past Stage 1 CCC problems, solutions (using Holt Software Turing or Ready: Java) and data files (both input and output). All of these are of course UNOFFICIAL.  All problem solutions were written by Chris Robart at Milliken Mills High School., except for the following:

Please email me if you find any errors, or have easier-to-understand solutions. Thanks.

The Official website is CCC.

Rating key (this is for just for fun, but does give some sense a problem's difficulty.)
* an average grade 11 student should get this
** an average grade 12 student should get this
*** an good grade 12 student MIGHT get this
**** the best grade 12 student MIGHT get this if given enough time
***** the teacher will get this after several days
