Hi iamstone, nice kata! I have just translated to Ruby! ;)

I have done everything right and reproduced all the tests, however when submiting there was no way I could get it accepted. I decided then unlock the solutions, but surprisingly there were no valid solutions.

It is optimized, otherwise it wouldn't take less than 4000ms.

By the way, I have reproduced your 27 tests and got at the end:

27 Passed
0 Failed
0 Errors
Process took 4101ms to complete

Are you sure your Ruby test cases don't have errors?

Ruby, when I run with an extra "." at the end of the string, the kata is completed (Incorrect, of course) showing:

0 Passed
27 Failed
0 Errors
Process took 3955ms to complete

However, removing this "." makes the process take more than 6000ms. :(

Man, when I run the final solution it says it took over 6000ms, but when I add any character to the final string, which makes all the answers to be wrong, it runs on time (~4500ms).

How's that possible? Does correct solutions take more time to compile than wrong solutions? :S

Hey, there is one thing to correct in Ruby version's tests. In the expected, I have changed to the following argument so the test could work !greeting_for_all_friends(["Bilal"]).nil?

Is this possible?

Test Passed: Value == 450010
Expected: -1, instead got: 450010.0
