Thank you @usx95  for the review. I have fixed the rest of the comments removed the change. I made sure the test formatting is the same as the style, around it. I also made the PR description shorter fixed the formatting rebased the GitHub branch I pushed the latest version of the code. Is there anything you would like me to fix with the code? Thank you again for the review of the code.
