"Problems" is a mailing list that intends to help high school students prepare for programming contests and olympics. However, this list is open to anyone who has email access and wishes to get involved.
Weekly, or maybe even more often, a problem to be solved is proposed on the list. The programs that solve the problem must be coded in C language (Borland C 3.1) or Pascal language (Borland Pascal 7.0). For additional rules that programs must obey, click here.
The moment you send a solution to a problem, you are automatically inserted in the solvers rating list. To find out how ratings are computed click here.
