PROGRAM EXPLANATION

Algorithm and explanation

  1. Read the sample input and convert it into the values required for read and greet a user.
  2. Apply input() and f-string to compute the required result.
  3. Display the result for read and greet a user and compare it with the documented sample output.

This example of read and greet a user computes the result directly from the prepared sample data. It demonstrates input() and f-string and prints a deterministic result that can be checked against the sample output.

DEBUGGING CHECKLIST

Common mistakes

Check this

For read and greet a user, keep the data shape and value types consistent with input().

Check this

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

Check this

Enter values in the documented order and convert text input to the required numeric type.

Try it yourself

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