PROGRAM EXPLANATION

Algorithm and explanation

  1. Initialize the sample values used to sort a list.
  2. Apply sorted() and reverse to compute the required result.
  3. Display the result for sort a list and compare it with the documented sample output.

This example of sort a list computes the result directly from the prepared sample data. It demonstrates sorted() and reverse and prints a deterministic result that can be checked against the sample output.

EFFICIENCY

Time and space complexity

Time complexity

O(n log n)

Auxiliary space

O(n)

DEBUGGING CHECKLIST

Common mistakes

Check this

For sort a list, keep the data shape and value types consistent with sorted().

Check this

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

Check this

Verify the final sorted() and reverse 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.
