This repository contains solutions to roughly 200 exercises from the book How to Design Programs. They were done during the summer of 2014. There might be a few incomplete solutions but most of them should be complete. I provide no guarantees of correctness but the tests should be passing for the completed exercises.
The second edition of the book was incomplete at the time I was doing the exercises.
The solutions in the htdp1 folder are from the first edition of the book.
I found these video lectures useful when I was reading the book.
