Ruby version is faulty. Description says a and b will both be <= 20000 but the tests expect values beyond that.

You might mention you want ALL people to get served. In my initial attempt I sent some people home so that others could eat.

Solution Set-up is wrong.

Can somebody tell me whats the input size? Description says that b <= 20000, but my IDE shows that my code can handle that in under 200ms, however Im getting timed out

NASM translation

Go translation

@riyakayal, C/C++ and Java translations available.

I suggest to use a pregenerated list of numbers for the checker function, as that would allow more time for user's solution and/or allow to check higher numbers.

Well these test cases look familiar ;-0

Maybe you should write your own tests cases for this kata instead of copying mine (which was written for a totally different kata) :P

• no sample tests
• description is missing what to do when dealing with negative numbers
• the nearest square to 0 or a negative number is NOT 1, this is 0...
