Java Today was very easy, but it took me considerable effort to wrap my mind around the problem. I was almost about to do a multithreaded solution when I facepalmed and implemented what I actually had to implement.

Java

Java Fun day, I like space cards. I had minor Vietnam flashbacks to the spacecards of last year, but luckily it was nothing like that. Some takeaways:

C++ part2 215ms on my laptop

C++ part2 35ms or so

Get the repository, then you can use cmake to build it like I do, or just use command line. If you want to test it with circular_buffer, you'll need boost, too!

In part1, though, vector was repeatably faster than circular_buffer. About 40us for vector and 70us or so for circular buffer. I expected circular buffer would out perform vector for this task.

C++ part1 part2

C++ part2 - less than 2ms on my laptop. Took forever to write. Lots of missteps. And room for improvement!
