Educational Codeforces Round 86 Postmortem

What went well

• Sampling other submissions, my solution to C is cleaner and more intuitive (if only it worked!!!)

What went poorly

• A took a long time
• My C implementation died to nuances of ceil(); I wanted to find the multiple of a number at least as large as some threshold.

Where I got lucky

• I was able to use fast-slow testing to determine a test case that breaks my C.
