This is becuase n squared is equal to 144. The sum of 1, 2, 3, 7, 9 all squared gives that solution but 1, 2, 4, 11 does not. It equals 142.

:-)

OK. Please be aware that the Random test output my expected values.

For example, the test 5 is saying dogYears=14 means owned for humanYears=0 ([1,0] the 2nd element - e.g. array index 1 is 0), but your solution returned 1

And that is the correct result (14dy -> 0hy) because Kata description says Results are truncated ...

So your solution is incorrect.

Please cut/paste the console log of your failing random test instead of re-typing it. I don't quite trust what I am looking at...

e.g.

Random test 1: catYears=8, dogYears=95 => [0, 16]
arrays first differed at element [1]; expected:<16> but was:<0>

It seems he only coded in Java so far.

Which language?
