Let's solve some hard problems!

Revision en6, by ivan100sic, 2022-01-06 20:00:50

Tonight, I will pick twelve 3000 rated problems I haven't solved yet, try solving them, and track my progress. As usual, I will not look at editorials. Hopefully I will be able to solve them all before the year ends. I will not make this my highest priority and I won't try too hard. I will keep solving other problems in the meantime.

The problems are:

  1. 341E - Candies Game
  2. 843E - Maximum Flow
  3. 1250D - Conference Problem (solved Jan 5, 3 days)
  4. 573D - Bear and Cavalry (solved Jan 6, 4 days)
  5. 1290D - Coffee Varieties (hard version)
  6. 568E - Longest Increasing Subsequence
  7. 788D - Finding lines
  8. 698F - Coprime Permutation (solved Jan 3, 1 day)
  9. 1342F - Make It Ascending (solved Jan 4, 2 days)
  10. 1236F - Alice and the Cactus (solved Jan 3, 1 day)
  11. 533A - Berland Miners
  12. 1411F - The Thorny Path
