In the Description, it says:

Output:

Your function must return the number of valid upside down numbers within the range of the two input arguments, including both upper and lower bounds.

It's spelled out in one sentence...I don't know how much more clear it can be.

It's all laid out in the Description. I don't know how much more clear it can be.

Output:

Your function must return the number of valid upside down numbers within the range of the two input arguments, including both upper and lower bounds.

Can you provide the details of your test case? What were the input values?

Under Technical Details:

• Each test case may have 0 or more possible solutions

Re-uploaded to imgur; used to be hosted on gyfcat but that site had shut down earlier this year.

Making a turn doesn't count as moving forward. In the test case you provided, the steps are move forward 4 units, turn right, move forward 2 units, turn left, move forward 1 unit, turn right, etc.

It's all clearly explained in the description. See section Conditions for passing inspection. The relevant point is the 2nd one: There is no conflicting information across the provided documents.

Having 74kg listed on one document and 75kg on another being reason for detainment not only makes no sense, it's inconsistent as well.

You only need to follow the instructions. 74kg != 75kg

Not an issue. There is no mention of height or weight.

I'm not sure why that occurs in the test case; I did not write the Java translation.

Thank you, @hobovsky. Approved 🖖

But CW will always remember your own setting for you.

Makes sense; this is what I encountered.

As for the comment in the initial solution setup (the line // use Node v10.x), I've changed it to // use Node v18.x.

Is there a way to make it default to 18.x? It doesn't appear to do it automatically after setting the version to 18.x (in the editor) and then republishing.

When I manually set it to 18.x afterward, then it remained at 18.x.

Fixed and updated to Node 18.x.

Fixed. If you come across any issues, feel free to comment.
