I was just wondering, what are the PE problems you liked the most and/or had the most fun coding?

Haven't really tried solving one in a long time...

I prefer the ones that don't really require complicated math and stuff.

The one I enjoyed the most(and also learned a lot from coding) was Su Doku.

I solved it ages ago, around the time I was starting to learn python.

That might be a part of why it was so fun to do.

I also liked the ones where you're supposed to determine the number of ways to determine the number of ways stuff can be done.

Dynamic programming and recursion are fun.

Out of the more recent problems, I really like Kakuro.

I'm planning to give it a try soon.

So, what are your favorite project euler problems?

Let's bring some life back to this section of the forum.
