PROGRAM EXPLANATION

Algorithm and explanation

  1. Import the required standard-library tools and prepare the sample data for use the math module.
  2. Apply math and sqrt() to compute the required result.
  3. Display the result for use the math module and compare it with the documented sample output.

This example of use the math module computes the result directly from the prepared sample data. It demonstrates math and sqrt() and prints a deterministic result that can be checked against the sample output.

DEBUGGING CHECKLIST

Common mistakes

Check this

For use the math module, keep the data shape and value types consistent with math.

Check this

Apply math in the same order shown by the algorithm; changing the order can change the result.

Check this

Check denominators, numeric ranges and rounding before comparing the calculated value.

Try it yourself

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