PROGRAM EXPLANATION

Algorithm and explanation

  1. Initialize the sample values used to check a leap year.
  2. Apply Nested condition and Logical operators to compute the required result.
  3. Display the result for check a leap year and compare it with the documented sample output.

This example of check a leap year computes the result directly from the prepared sample data. It demonstrates Nested condition and Logical operators and prints a deterministic result that can be checked against the sample output.

DEBUGGING CHECKLIST

Common mistakes

Check this

For check a leap year, keep the data shape and value types consistent with Nested condition.

Check this

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

Check this

Verify the final Nested condition and Logical operators 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.
