see the comments below. this solution was written in Pyrthon 2. Python 3 changed the round() function for halfway cases: it used to be half away from zero (0.5 --> 1, 1.5 --> 2), now it's half towards the nearest even integer (the so-called "banker's rounding"): (0.5 --> 0, 1.5 --> 2)

Approved.

Yeah! :)

This isn't really a practical solution when it comes to a professional setting. They would prefer you to unpack that a little lol just a more clever solution

What this comment for? Atleast, from now on, you will know about this lib [^-^]
