To quote @N-Parsons in #1030:

Please use a meaningful title for the PR that includes the exercise name - it makes it much easier to handle pull requests. I would suggest using all-your-base: Update test order and version string". Could you also please add the magic words resolves #1014 to your PR description so that merging list PR closes the corresponding issue.

In your case, the corresponding issue is #1020

Fixed styling issues.

Thanks, @kishan3
