L-99: Ninety-Nine Lisp Problems

Postby ebie » Wed Jul 07, 2010 8:56 am

I was wondering what others thought about these exercises. There doesn't seem to be much discussion about them. Are they worthwhile? Has anyone worked them all?

I'm asking because I've reached the binary tree section and my solutions are getting really ugly. Without the solutions to learn from (they stopped at problem 28), I feel like I am not moving toward my goal of being able to write efficient and clean code.

Thanks for your comments.

This link? http://www.ic.unicamp.br/~meidanis/cour ... blems.html

Never looked at them before. Look like a reasonable set of exercises, though the first few do assume you will use a "basic" subset of CL or Scheme.

Yes. Sorry, should have been a little more specific.

They built steadily from one to the next right up until problem 50 (Huffman Coding).

Yesterday I implemented about the first 40 of them in PicoLisp, so I posted them
now on: http://home.picolisp.com -> Examples -> Ninety-Nine Lisp Problems.
