Codeforces Round #635 (Div. 2) Postmortem

What went well
  • A was trivial.
  • B was easy.
  • I didn't feel stuck when attempting D.
What went poorly
  • C took a long time because I didn't realize that I had to consider two criteria for the greedy solution (first Wrong Answer). Then I didn't realize that the two criteria were not mutually exclusive (second Wrong Answer). All said and done, I spent 1h30.
Where I got lucky
  • Somehow still above 1700!
