This kata is hard. It took me a while to figure out the logic. It is very satisfactory one you successfully pass all the tests. It is better to do the simpler version of the kata first, then reuse the code and do necessary amendments.

Rust translation

The author of this kata states "There are no complicated formula that propagate many errors". I solved the kata with a rather complicated formula and it did propagate many errors, till I figure out when and where to do the notorious rounding.

There are 100 random tests...

I passed 10-13 random tests and then it times out, so it seems there are several random tests. One of the posts below says there are around 25 random tests, could be more. My code takes average 500ms to pass one random test, I believe I will have to pass each random test in less than 100ms to complete all tests.

Very dedicated coder. I would hire you ;-))

Great kata! Finally I managed to pass all tests. The kata requires a lot of circle geometry, tangent lines, circle intersections etc.

geoffp has been writing great katas. Last week I solved a kata, written by him, on Optical Character Recognition, which was challenging and fun. I have been working on this kata for a couple of days now and still hasn't come across any strategy to solve it. Let's see how it goes...

Good use of simple maths. Though, it is not considered a best practice to write a long unreadable code. ?: operators are considered less readable then if..else statements.

The solution can cause stackoverflow with large numbers.
