Style Update?

[jwblackston]

Hi @Aafreen29,

Thanks a lot for creating this repo - it's helped me considerably in my prep for upcoming interviews!

I have nothing substantive for an issue, but perhaps a suggestion or opening of a conversation around style: wouldn't it be preferable to not write the queries in one line, as well as indent and uppercase clauses where relevant?

I am early on my SQL journey but I just read a good bit about this being preferable when sharing with your team for enhanced readability.

Thanks for this again and great work!
