Reflection

Overall, I enjoyed them. They reminded me of when I used to work on Project Euler problems. I'll admit I was a little like "meh" when I solved the second one. The insight that every other char is an edge renders my BinTree pointless. But I kept it in there since that's how I got that insight. (I always hated that on Project Euler, too, when I would write some code that I would be really proud of, and through the process of writing it and refining it, I'd finally realize that all of it was irrelevant due to an insight like this).

I also didn't like on the second one how they called it a binary tree. I thought of a couple examples that proved the problem couldn't be solved, and walked away. The next day in the shower, I was thinking about what implicit assumptions they must have made that allowed that problem to make sense, and I realized they must have meant for it to be balanced, causing each non-leaf to have exactly 2 children.

I enjoyed the third problem, but suspect my solution isn't the algorithmically genius way of doing things. I thought about looking up the right algorithm for it, but whatever. I do these to challenge myself, looking up and then implementing the best solution is what I'd do if this were for something in production. But that isn't what this is, this is just exercises to challenge myself, so I decided to solve it myself.


This code is unmaintained.

If you do something interesting with it, let me know so I can be happy.
