🛹 Demo 5: Ackee's X Example

(Mia's quick solution)

A classical exercise for folks to learn PDAs in practice is Ackee's X App example: a program that can perform basic functions like:

• creating tweets, including a topic of up to 32 bytes and content of up to 500 bytes. The topic is the seed for this PDA (so users can have more than one tweet).
• adding/removing tweet reactions, covered by a new reaction account and PDA. In this case, the seeds for this PDA are chosen to prevent more than one reaction per user on a tweet.
• adding/removing tweet comments, including a content field (500 bytes) that stores the text and is used as input into the comment account PDA.
