[Back to the Archive]
Reach out to share your solution and have it included here! :)
- A group of 10 people are seated around a circular table. How many ways can these people simultaneously shake hands such that none of the handshakes cross each other? (Check out page 2 of the handout for a helpful picture of what we mean! :) How is this related to the parentheses problem?
- Not really a challenge, but perhaps you'd like to read more about Ada Lovelace.
