PROGRAM EXPLANATION
Algorithm and explanation
- Initialize the sample values used to use variable-length arguments.
- Apply *args and sum() to compute the required result.
- Display the result for use variable-length arguments and compare it with the documented sample output.
This example of use variable-length arguments computes the result directly from the prepared sample data. It demonstrates *args and sum() and prints a deterministic result that can be checked against the sample output.

DEBUGGING CHECKLIST
Common mistakes
For use variable-length arguments, keep the data shape and value types consistent with *args.
Keep every dependent statement inside the correct indented Python block.
Verify the final *args and sum() result against the sample before trying new data.
