PROGRAM EXPLANATION

Algorithm and explanation

Import the required standard-library tools and prepare the sample data for combine values with reduce.
Apply reduce() and functools to compute the required result.
Display the result for combine values with reduce and compare it with the documented sample output.

This example of combine values with reduce computes the result directly from the prepared sample data. It demonstrates reduce() and functools and prints a deterministic result that can be checked against the sample output.

DEBUGGING CHECKLIST

Common mistakes

Check this

For combine values with reduce, keep the data shape and value types consistent with reduce().

Check this

Apply reduce() in the same order shown by the algorithm; changing the order can change the result.

Check this

Verify the final reduce() and functools result against the sample before trying new data.

Try it yourself

Practice: Run the program with the sample input, predict its output, and then test one boundary case of your own.
