Questions related to programming exercises that are meant to increase students' skills. Use this tag to ask questions about exercises related to a specific skill or skill-set.
Note that some exercises only work in certain contexts and/or with certain preparation by the instructor. Some exercises have issues that the frequent user might know about but that an adopter might not. In asking questions about exercises it might be a good idea to request that the answers be given in context with caveats and exceptional cases explained. Be sure in your question to mention what objectives and/or outcomes you are trying to achieve when using the exercises that might be given in answers.
