I recently received response videos to a number of earlier challenges, so I'll summarize the updates here. Click the links below to visit the archive page for each challenge, where the new videos are highlighted. Plus, you can watch the original challenge video and the other responses, and take on the follow-up challenges.
- A new solution to Challenge 01, in which our problem solvers go back to the beginning and hope to count the even "Ermer Numbers".
- A new solution to Challenge 03, in which our problem solvers take on the most popular challenge from the spring, "Finger Counting".
- A new solution to Challenge 04, in which our problem solver sets about to explain how we know we have found the minimum number of button presses on the less-than-useful "Two-key Calculator".
- A new solution to Challenge 05, in which our problem solvers bust out the rulers for a practical approach to "International Paper".
