Mock CCC '18 Contest 1 Senior

This is the first contest in a series of mock CCC contests produced and tested by ksun48, rpeng, xiaowuc1, and y0105w49.

Much like the real CCC, you will have 3 hours to do 5 problems with full feedback. You may submit no more than 50 submissions per problem. Additionally, the scoreboard will be disabled during the contests.

There are no explicit subtasks included in the problem statements: each test case is 1 point.

Unlike with other contests, these problems contain no flavortext.

This contest will not be rated.

CCO cutoff using this contest would have been a 62.

    Why can't we access problems after contest end? Also, are there going to be editorials? EDIT: You have to virtual join to see editorials.

    Of course, the one time that I didn't fuck up a contest, I accidentally used an alt

      If you get above a certain magical number on the actual contest, you get a free trip to see the dragons of loowater. I suggest aim to not get rekt on the actual round, than increase ratings.

    The actual CCC has subtasks though, why doesn't this?

      because 4 people don't have that much time, especially with 5 contests and subtasks aren't all that important :)

        Fair enough about the time thing. However, sub tasks are pretty important, lots of people made CCO last year through only solving 2 questions and getting sub tasks for the other 3... :p

          Subtasks aren't specified, but partials are awarded.
