This problem needs an update due to changes in scoring system in Cody

Rafael S.T. Vieira on 20 Sep 2020

You need to specify the comparison method when sorting complex numbers. Any change done to the order of elements currently creates an invalid solution (even sorting elements), and I guess the one that you want is 'real'. Or don't use complex numbers and create pair of values [x,y]. I've commented my solution. Futhermore, the function calculateSize no longer exists.

Would someone please fix the test? The function calculateSize does not exist.

Dyuman Joshi on 30 May 2022

The test suite has been fixed, Chris. You can now attempt the question.

Thanks Dyuman
