this might be helpful, read the first bit of this page:
https://www.ibm.com/docs/en/ts3500-tape-library?topic=functionality-ipv4-ipv6-address-formats

Two years later I have the same comment to make. It is contrary to how built-in functions round decimals.

I am having the same issue, see my post above with an attached image

You have to return number of possible IP based on the provided range

Hello there, I know the reply is pretty late, but if you are still interested in solving the question...
Let me break it down for you...

//original IP address
192.168.1.1

//breaks down into 4 binary octets
11000000 . 10101000 . 00000001 . 00000001

//which are merged together (unsigned 32-bit binary)
11000000101010000000000100000001

//and finally converted to base 10
3232235777

now you can find the difference!

Great, marking this as resolved then.

What browser are you using? These are rendered with SVG, and it's possible that your browser is drawing them incorrectly. In the second test case, the point is well inside the square, and in the fourt test case, it is well outside the square. In the sixth test case, the point is very much inside the triangle.

I've checked this in Chrome, Firefox, and Safari, and in all three browsers, it renders correctly.

Please, check JS. 2nd & 4th tests - point lies on the border. 6th test - point is obviously outside.

Which language? I checked JS, CoffeeScript, and Haskell. In each, the third test expects the point to be outside.

this is because the object you are trying to split does not have that method in the prototype, so it's not a string. you may need to check your types before trying to use split.

array[-1] returns undefined

Glad you liked it :)

How does the first check even pass?... you are accessing ints[-1]... apparently JavaScript does not have a problem with that :)
