the array it's the sequence of last digit in fibonacci's numbers. Every 60 numbers the sequence start over

There aren't. This is a normal array with all items from 0 to 'T'.

Thanks. I figured that one eventually since 170+ had already done it in C. Looking at the other solutions I went with a little overkill though but to be honest it was just good to get it done.

Oddly I didn't get notified of your response here though.

@Evgen8

I see in your profile that you passed this one using C, is that correct since I am still getting:

ShouldPassAllTheTestsProvided
The expression arrayEquals( arr, sizeof(arr) / sizeof(arr[0]), expected, sizeof(arr) / sizeof(arr[0]), sizeof(char*), strcmp) is false.

So don't see how it's possible, is the issue still open?

language? If C, you can close the issue: dupliacte of others below.
