There is a security hole, look at my solution :)

Kata is unpublished until i fix some serious issues

Made clearer, thank you for your feedback

Modified

At first thank you for feedback, i added your questions to rules

Test.assertEquals(fv([ 20, 1 ],[ 70, -55 ],11),0) tells that fib starts at 1,20 then goes to 1,20,21,41,... but it doesnt matter because array length is 2 so first pair 1,20 is out of range so you should return 0

And well as I'm looking for second input something went wrong and i'm gonna rewrite that a little, second input in wrong.

Also I'll modify test cases.

Recently I looked for my leaderboard position. The number doesn't give user useful info. I'd suggest to add some percentage of top in addition. Also it would be good to have this percentage within language. With this feauture user would better understand how good is he amongst other users.

Hey, I'd like to learn about this topic and later try this kata but now I dont get that :P Can anyone post some materials about this?

Thanks a lot! :)

Missing definition for vowels, at my country is "aeiouy", somwhere else it's "aeiou" only.
