Eval, generator, solver
The first task on a preec must be a real trivial task so that teams can try out the submission system without having to code much for a solver.
The generator, solver and an eval are all available. The eval reads the internal eval format: first line is the input file number in decimal, from 1 to 10, the second line is 0, then the submitted solution. Since there's an exact solution, the eval prints 1 when the solution is accepted and 0 otherwise. After the 0 it also prints the reason to help the organizers debug.
Note: the generator may not generate the same input files that we have in the input pack, because it does not implement a portable/reproducible random generator. Rationale: we knew we have to run it only once then the input files are published as static files.
