To all saying "Ugh no time!" At this point, there are still 7 and a half hours remaining. You can easily qualify (20 points) in under an hour.
That being said, #4 is the only one that tripped me up - I'm think the solution is very simple and elegant but all I can think in my head is something along the lines of ray-tracing. Back to the drawing board!

- etherealG 15y agowhere did you find that 20 points to qualify?
- dmaz 15y agoPosted at the top of the scoreboard. The FAQ pointed to this for advancement.
- victzh 15y agoThanks for encouraging words, I was not able to solve D (no time left - I started 2.5 hours before dead-line, and did not exercise before), but got 60 points for other 3, enough for 1st round.
- prezjordan 15y agoNice job, same boat as me. I'm excited to see Google's write-up of D. Good luck in Round 1!
