Improve package organizations

[eduardogr]

There's a lot of main packages in this project

sorts/selection_sort.go:1:package main
sorts/Heapsort.go:1:package main
....
....
other/PasswordGenerator.go:5:package main
other/PrimeNumbers.go:1:package main

We can improve this package organization to let each package have its place

This would also fix all the failed golangci-lint test. Currently they fail because multiple people use the package main.

It's a good idea. I'm trying to fix this (both package and filename convention). I'm starting with sorts. You're welcome to help with other parts.

[eduardogr]

How is this going? Do you need help with this?

[vedantmamgain]

@eduardogr That would be great if you can improve the package organization.

I believe this issue has been resolved with the PR #266. Now it only remains for us to add tests for each function so that everything works as the implementor expects it to.
