TL;DR Took me several hours, but I finally solved the problems on my own, without any kind of help or search engines. My first real taste of what it's like to code.
I know it's not much, but this is the first time I actually put my head down and came up with a solution all on my own. Didn't even read the hints, or look anything up on the internet for any of the problems.
The first one was fairly simple. I had a lot more trouble with the second, the one the author says they fail a lot of people applying for a job on. The third was the hardest, it must have taken me several hours to complete it.
It's a very peculiar experience. I had no idea what I was doing, but as soon as I read the problems I walked around thinking on possible ways I could solve them with what I had just learned. Particularly with the third one, I went through like 7-8 different drafts, each time getting stuck on something and starting a new page to try and come up with a way to get past it. I ended up creating new ways of going about it with each new iteration, and finally I thought I had it, but then 3 more separate times I noticed the program wasn't working right when checking different values.
Anyway, I did it eventually. Programming is fucking nuts, honestly.
I know I'm still early in the book, but I plan to stick with it for as long as I can. I see a lot of people saying it's not good for beginners, but I hope if I read everything multiple times if necessary, I'll be able to solve whatever he gives me. Presumably he teaches all the tools you need for the job. Great book, either way, really recommend it.
These here are the problems(you can also use the site to read/learn from the book, or even copy it to Kindle or whatever – also, for writing down and running the code for the exercises):
Edit: I'm also reading Turing's Vision by Chris Bernhardt right now as a more light kind of literature. It's about Turing's Universal Machines, his "On Computable Numbers, with an Application to the Entscheidungsproblem" paper, the math surrounding all of it, and things like that. It's a very interesting read, I'm learning stuff about Computer Science and its origins. I recommend it; it's a lot of fun. Please share any similar recommendations if you have them(I mean in terms of lighter reading surrounding CS).
