8. Understanding solutions

• Each solution contains code and settings to obtain the output record from the input record

• Coding stream participants will be able to modify both source code and settings, or create new solution classes

• Non-coding stream participants will be able to choose among the pre-existing solution classes and modify their settings

• Each solution has a unique identifier, making it possible to experiment and compare different settings

• A special solution with ExpectedResults identifier contains human-validated results for scoring
