Test a custom input to verify an edge case (e.g. empty lists, negative numbers, duplicates).
This bug belongs to the mutation and copying bugs pattern
Assignment does not copy, a shallow copy still shares its contents, and mutating methods return None.
What went wrong: looping over a dict gives only the keys. "asha" cannot be split into name and score.
The fix: for name, score in scores.items():
Remember: use .items() to loop over keys and values together.
The pattern behind it: mutation and copying bugs.
