These are 40 questions and answers I gave to a coder dojo group, with supporting utilties to display questions and answers at the console.
show-questions
is a python program than shows all questions
show-answers
is a shell program that diffs questions.txt and questions-answers.txt
for a particular round, starting at 1
questions-answers.txt is created first, with a blank line separating questions. When finised, just delete the answers in a copy called questions.txt
The 40 example questions here took about 90 minutes to go through. The teams were given standard blank table quiz sheets to fill out their answers.
