Problem 1339. Travelling Salesman Problem (TSP)

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

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.
