Merge branch 'hw-class-03' into 'main'

I've learnt about fast-forwarding and how it works. I've always just seen it when pulling, but never truly understood what it meant. I've also learnt what upstream means.

git switch main

git branch --list

git switch -c hw-class-03

cd ..

cd class3_homework/

nano 525139.txt

git status

git add 525139.txt

git commit -m "chore(hw-class-03): Add what I've learnt so far"

git push

git push --set-upstream origin hw-class-03
