Check Other People solution Without Submitting as your own

It's a good practice to see how other people have solved the same problem.
In some solutions it's claimed they are 90% faster and 50% memory efficient.
Can I not run these codes where they are mentioned and see how they perform.
I don't want to copy and submit other people's code as it becomes a part of my submission.
Does a functionality exist to support what I am trying?
Otherwise can you please add one.
