PROGRAM EXPLANATION

Algorithm and explanation

  1. Initialize the sample values used to use the constant naming convention.
  2. Apply Constants and Naming convention to compute the required result.
  3. Display the result for use the constant naming convention and compare it with the documented sample output.

This example of use the constant naming convention computes the result directly from the prepared sample data. It demonstrates Constants and Naming convention and prints a deterministic result that can be checked against the sample output.

DEBUGGING CHECKLIST

Common mistakes

Check this

For use the constant naming convention, keep the data shape and value types consistent with Constants.

Check this

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

Check this

Verify the final Constants and Naming convention 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.
