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

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