LGTM. Waiting for @coryan for final approval.

If there is a reason why downloading 5 and 2 bytes to a file is the best approach (e.g. because that is what the examples in other languages do) then please merge as-is.

But otherwise, it seems overly complicated to create files when a simple buffer would do.

[coryan]

Why download to a file? That seems more complicated than downloading to a buffer (specially for 5 bytes!) and distracts from the main topic of the example.

[vsharonlynn]

Thanks for your inputs! I agree with your concerns.

Here are my changes to simplify the logic to focus on the main topic of the example:

• Write to file --> Download to a buffer and printing
• Downloading 5 and 2 bytes --> Download 5 bytes for both ranges
• Clarified print statements to say "Read first range[...]" and "Read second range[...]" and print the content.

Please let me know if this version is clearer.
