San Francisco Live Tournament Recap

San Francisco Live Tournament Recap

On Saturday, April 22, CodeFighters from all over the Bay Area packed into the new CodeFights office and made history at the first-ever live San Francisco tournament.

Some long-time CodeFighters already knew each other, but for many it was their first time meeting up with other users in real life. The room rang with friendly chatter… right up until the tournament started, and then everyone got down to business.

The packed room was nearly silent during the hour-long tournament. CodeFighter xiaowuc1 pulled ahead early, solving all 10 challenges in under 15 minutes.

12 people were able to complete all 10 questions in the hour allotted, while 4 users finished 9 questions, 3 finished 8 questions, and the rest of the pack finished 7 or fewer. The questions started off fairly innocently and then ramped up in difficulty quickly! The last few were especially tricky:

  1. isEarlier
  2. onlyEvenNumbers
  3. lrSegmentNumber
  4. sequencePeakElement
  5. parkingCost
  6. findPath
  7. numberOfCarries
  8. holesErasing
  9. rangeCollapseRepresentations
  10. subdomains

Check out xiaowuc1 explain how he solved subdomains using tries:

Special Shoutout

While he wasn’t able to make it into the city to compete in person, CodeFighter Pedro_O (Pedro Osório) participated remotely, solving the challenges in Python. He finished in 33 minutes and 33 seconds.

Thanks!

We had so much fun hosting this! Thanks to everyone who came out to compete, meet other CodeFighters, and hang out with the CodeFights team. It was great meeting you all!

We’ll definitely be holding more live coding tournaments in the future. In fact, it’s going to become a regular event! We’ll let you know when the next one’s scheduled – and hopefully we’ll see you there!

CodeFight on!
