Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.
Nice, even if it appears having issues with cases in which one of the bounces isn't strictly > of window, like this:
assertEquals(1, BouncingBall.bouncingBall(2.0, 0.5, 1.0));
I like this idea too. the code is very clean
I like the idea, I Too it and replaced array copy with Arrays.asList and subList, which should be better for Performance.
Impotent to notice here this solution isn't performance-wise.
It allocates in memory lots of intermediate arrays. That might be costly and has to be avoided.
very nice

I solved that issue by using Math.ceil() instead of Math.floor, and then subtracting 1. This will give identical results in all cases except when the bounce takes you exactly to the window, in which case it'll subtract that bounce out.
You should do a very simple code(KISS principle). May be after 5-10 years you would do it like this, may be not.
imho it is not necessary.
Something like this:
int[] a = {3, 2147483646};
int[] b = {9, 4};
returns true...
ну ты гнида
Math.floor
is unnecessary because(int)
will truncate the fractional part of thedouble
.I wound up using this method because both my recursive solution blew up the stack and my iterative solution took too long.
i think that this code work very slow on big numbers

how can i learn to code like this?
1 is not prime and 2 is prime. Your isPrime is incorrect.
