PROGRAM EXPLANATION

Algorithm and explanation

  1. Initialize the sample values used to convert decimal to binary.
  2. Apply bin() and Slicing to compute the required result.
  3. Display the result for convert decimal to binary and compare it with the documented sample output.

This example of convert decimal to binary computes the result directly from the prepared sample data. It demonstrates bin() and Slicing and prints a deterministic result that can be checked against the sample output.

DEBUGGING CHECKLIST

Common mistakes

Check this

For convert decimal to binary, keep the data shape and value types consistent with bin().

Check this

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

Check this

Verify the final bin() and Slicing 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.
