Can't figure out this while loop

Note sure what I'm missing?

loop.rb 
i = 0
while i > 5
  i += 1
end

You just got the less than and greater than sign mixed up a bit! Try this:

i = 0
while i < 5
  i += 1
end

This loop will never run. You initially set i to 0, but the loop will only run if i is greater than 5. My bet is that you meant less than. This will fix that:

i = 0
# Notice the reversed comparison sign
while i < 5
  i += 1
end

To be fair, it's rarely the giant logic flaws that get us, is it? It's always the misspelled variable or missing quotation mark, etc! That's why it's so nice that people hang out here on the forums. Some days it's nice just to have an extra set of eyes! :)
