Summary

This PR improves the bubble sort implementation by making the code more robust and following C best practices.

Changes

• Added a NULL check after calloc() to handle memory allocation failures.
• Removed the unnecessary cast from calloc().
• Eliminated unused main() parameters.
• Fixed a typo in the comment ("Intializes" → "Initializes").

These changes improve code quality without affecting the algorithm's behavior.
