SICP Study Group 2.2.1-2.2.2 - Data Structures From Cons Cells

Since SICP section 2.2 is so large, we will be breaking it up a bit. This session will focus only on the first two sub sections: 2.2.1 and 2.2.2.

Feel free to come out even if you haven't done the reading. We will be discussing how you can make data structures (lists and trees) with just simple pairs/tuples/cons cells.

    I would love to see someone's solution for exercise 2.32. I came up with a recursive solution that technically works, but it gives the answer in an order that is different than what the exercise asks.

      Nope, I tested with Tom's solution but without an anonymous function and It works fine: I guess I just couldn't wrap my head around doing it that way: https://gist.github.co...­

      My solution works fine, and it's easier (at least for me) to understand what is going on, but it's definitely not as succinct.

    Hi -- I responded to David's message below with my solution, but didn't get an email alerting me to a new comment. Thought it might be because I replied to an existing comment rather than entering a new one. So I'm entering this just in case it triggers the email alert.

    Will have done the reading (and hopefully some of the exercises) this time. Looking forward to it.

      Great! You'll get proportionately more out the more you put in!

I decided to start Reno Motorcycle Riders Group because I wanted to be part of a group of people who enjoyed my passion... I was excited and nervous. Our group has grown by leaps and bounds. I never thought it would be this big.
