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

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