“It’s rewarding. It feels good to come up with a solution, and just to in general practice how you approach solving problems.”
During his visit, he was kind enough to give us a great walkthrough of his solution. He started by talking about his original naive solution, and then about how he optimized it. It’s really interesting to see the code’s evolution from its (still great!) beginnings to the expressive, readable, and concise solution that you can see at solution #191. Watch his explanation below!
We’ll post the next two solutions when our other winners visit us later this year, so stay tuned!
See the winner’s solutions section of this post for their full solutions to the challenge secretArchivesLock! We’re going to be posting an in-depth explanation of each winner’s solution, in the winner’s own words, so stay tuned for that in the next few weeks.
All CodeFighters can solve this challenge, but only people in the U.S. are eligible to win.
Your solution must be submitted before the contest closes at 12:00 PM Pacific Time on Wednesday, July 26.
The three winners will be notified by email and their names will be posted on the CodeSignal forum by 5:00 PM Pacific Time on Friday, July 28.
