Improved file structure

[AkshatAggarwal14]

This PR does two things:

1. Move templates into different directories according to their language.
2. Fix typos

Thanks for the PR!
Nice work, I was wondering if we could use different naming conventions for file names.
currently, we use small cases for all languages except Java.
What do you think?

i think we should use small cases for all languages

Sorry for inconvenience, but i think it would be better to keep java file name as their classname to avoid any confusion.
So please avoid renaming Java one's to small as well.

We are not running this code, so i dont think it matters if we change the case or not. If all files follow the same case, it looks consistent.

Still, someone may want to run templates to see if it's working.
I hope that makes sense.
