This is a strange one, because the acceptance tests do not test for this.

If you also want to capitalize the last word add this code to the end: .sub(/(\w+)$/,&:capitalize)

Test cases changed. But, I haven't add the testcase like a, b = [1,4,1], [1,3,2], just increased the testcase which expected false and two arrays have the same elements but different order(of course, their sums are equal ;-))

Added to all languages ;-)

Also apparently every language has a different idea of how to handle 0. So I've made every language consistent (now they all expect 0) ;-)

I rewrote my solution

It would be much faster if you raised an issue about the Ruby tests being pretty inexistent. Now I've added random tests.

Huh, I never noticed that when writing the solution!
Looks like the Kata needs more tests.
