Best of COCI #2

Revision en3, by MladenP, 2021-11-18 22:34:14

Since the second round of this season of COCI (Croatian Open Competition in Informatics) was held last saturday, here is the continuation in the series of COCI appreciation posts (I will post one after each COCI round, so six in total!). For my coaching, I went through all COCI contests since 2006 to gather tasks and selected some of my favorite ones.

Notes

  • Check out the first post for notes about the process and the problemset.
  • There are 9 tasks in this problemset since I accidentally forgot to put one task (Zoo) last time, so it's included now.
