1st part: inverse proportional to (solved)?time to solve:max time

2nd part is correct. You get additional points for any test case that faults the code. You get demerits for trying a test case that fails (by being handled correctly by the adverse program)

Many reasons to want to use Perl sometimes. Just 2:

• There are problems that are just made for regex handling.
• creating and using a map using the stl (in C++) is way longer than using a hash (and time is a factor)
