I keep receiving emails with problems sets and questions about OCaml programming mostly from readers of the "99 Problems in OCaml". Many thanks to those who wrote me! I am happy to reply as soon as I can, however note the following :

• Please don't send me problem sets from assessed coursework. Assignments are meant for you to thrive on, and for your teachers to measure your/their progress.
• Don't send me problem sets handed out by companies for interviewing purposes. If you don't manage the application procedure, you won't cope with your job.
• If you do send me a problem to solve, expect me to make the solution available to the public. If you need me to not undisclose either problem or solution, indicate it in your email.
• Send your question/problem to ocaml(at)christiankissig.de.

Below you find the solutions to some problems.
