Indeed it is fixed now - thanks!

Random cases expect faulty results such as

Should return the smallest int 90002274117 - Expected: 90002274117, instead got: 115144648
Should return the smallest int 72055419231 - Expected: 72055419231, instead got: 2362998
Should return the smallest int 38974336348 - Expected: 38974336348, instead got: 17385394
Should return the smallest int 57805849588 - Expected: 57805849588, instead got: 9118625

Fixed cases pass

I can't even remember why I took this approach.
Guess it was pretty late and I was still at the office. ;)

Stumbled upon the same issue.
The format has to be identical like in the example: apostrophes instead of quotes around the URL.

~~What is the 4th test case?
I always receive an 'did not return pairs with the correct value'.
Tested with int & char. ~~

~~Have I missed something? ~~

I am an idiot.
