At work we are doing a coding competition on hackerrank – it is real coding – you are given input and you have to code a program that produces the correct output.
Now, I would like to promote this kind of challenge/puzzle at an event, where we will not have access to computers. I'm looking for a similiar kind of puzzle, but with pencil and paper.
Is there some way to create coding based puzzles with just pen and paper? (It can be trivial)
