For anyone interested, I’m hosting a YouTube stream five minutes after today’s contest to discuss the solutions to whichever problems I solve (including all problems from Div. 2/Div. 3). Check it out at https://youtu.be/g2D3lSgHBQI if you’re interested–I hope to see you there!
I will be there.
Apologies for the technical difficulties–I’ve restarted the stream; link here: https://youtu.be/g2D3lSgHBQI
Thanks to everyone who joined the stream! A recording is available at the above link. I’ve also uploaded my screencast at https://youtu.be/QrdEPqqKg8o if you’re interested in seeing me solve the problems live.
