Week #9 DS Challenge

TCO Announcement Marathon means that there is something interesting happening in Data Science tracks this week, so I can announce the challenge: the t-shirt will go to…

Week #8 Algorithm Challenge Result

As a reminder, the week #8 Algorithm challenge was…

…The competitor who does the latest successful challenge in Algorithm Round 2A.

14 minutes and 57 seconds into the Challenge phase (that’s what I call last-second!) gangsterveggies successfully challenged nshal’s 500-point problem. Congratulations!
