    He's also a setter, of the challenge problem. So he did compete on the challenge problem, in a sense.

    I'm imagining the checker of the challege problem to contain something like "IF COUNTRY == NK && TESTING == FINAL: BAN"

    One of them had a mistake, found a day before the contest, so it got delayed; it looks like it could be up today or tomorrow. The other... well, let's hope it will get added.

    So far, you can focus on solving my problem :D

I am struggling with this solution for Rohith and Circles problem. Particularly, I do not understand where the line yl=(.25*((1.0/r4)-(1.0/r3)))-rs; comes from. (This is the y-coordinate of leftmost circle after transformation).

Maybe someone can help me to figure out this? Thanks.
