Add complete solution for range_overlap example

[tmorrell]

Please briefly summarise the changes made in the pull request, and the reason(s) for making these changes.
The range_overlap example stops before giving a final solution, which is annoying if you're teaching from the curriculum. The assertions also change order for no particular reason.

I fix the order of the assertions, and add the complete working function.

If any relevant discussions have taken place elsewhere, please provide links to these.
Replacing this example has discussed for years #979, but there hasn't been a good proposal. This PR just makes the existing curriculum more useful, and it's fine if it gets replaced at some point in the future.
