Help with array

[Matthew Boston]

I'm working through the rubykoans and I cannot figure out one of them.

array = [1, 2, 3, 4]

Why does array[4,0] return [] but array[5,0] return nil?

From RDoc:
Returns nil if the index (or starting index) are out of range.

That means array[4,0] would return nil, right?

Thanks for the help.
