Codeforces Round #607 (Div. 2) Postmortem

Link to contest.

What went well
  • I solved A in 2 minutes.
What went wrong
  • I was too hasty on B, leading to two wrong submissions, and took a total of over 20 minutes.
  • I took over an hour on C because I wasn't clear at all about my recurrences and starting values. 
Where I got lucky
  • Everyone else sucks more at math, so a slow C with one penalty got me in the top 400 (top 6%).
