Mock CCC '18 Contest 5 Senior

This is the final contest in a series of mock CCC contests produced and tested by ksun48, xiaowuc1, and y0105w49. rpeng does not endorse the problems of this contest.

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.

This contest consists solely of problem ideas rejected for the Valentine's Day contest.

This contest will not be rated. Please do not discuss the contest until after the contest period is over.

CCO cutoff using this contest would have been a 63.
