Hi Steve!

In solution #2 I use a.min

def find_smallest_int(arr)
  arr.min
end

And in my opinion, this is the best one.

Sorry, I didn't see that one - screen too small. I just heard a couple loop solutions.

Thanks for the feedback!
I'll use bigger font size and will give more info about all approaches before writing the code.
