PROGRAM EXPLANATION
Algorithm and explanation
- Initialize the sample values used to use match case for a menu.
- Apply match and case to compute the required result.
- Display the result for use match case for a menu and compare it with the documented sample output.
This example of use match case for a menu computes the result directly from the prepared sample data. It demonstrates match and case and prints a deterministic result that can be checked against the sample output.

DEBUGGING CHECKLIST
Common mistakes
For use match case for a menu, keep the data shape and value types consistent with match.
Apply match in the same order shown by the algorithm; changing the order can change the result.
Verify the final match and case result against the sample before trying new data.
