PROGRAM EXPLANATION

Algorithm and explanation

  1. Initialize the sample values used to perform set operations.
  2. Apply Union and Intersection to compute the required result.
  3. Display the result for perform set operations and compare it with the documented sample output.

This example of perform set operations computes the result directly from the prepared sample data. It demonstrates Union, Intersection, and Difference and prints a deterministic result that can be checked against the sample output.

DEBUGGING CHECKLIST

Common mistakes

Check this

For perform set operations, keep the data shape and value types consistent with Union.

Check this

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

Check this

Verify the final Union and Intersection 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.
