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

DEBUGGING CHECKLIST
Common mistakes
For select values with filter, keep the data shape and value types consistent with filter().
Apply filter() in the same order shown by the algorithm; changing the order can change the result.
Verify the final filter() and lambda result against the sample before trying new data.
