## Comments

Are there any solutions or hints for these problems? Thanks.

When admins get the time, could you make the submission sections of the problems available.

Since it is unrated can the time period be extended so we can solve after the 3 hours has ended?

This has always been possible, just go to

`dmoj.ca/problem/problemcode`

post-contest.Note that this contest is

unratednow.Yay from 80% of the people (including me) who would probably get a grand total of 0 ACs.

There goes my chance of getting Master.

Thanks a lot, FatalEagle!
