8,916 PointsProblem solving Ruby loop challenge
I can't seem to solve the loop challenge for Ruby. I've attached my code. What am I doing wrong here?
numbers = []
number = 0
# write your loop here
loop do
numbers.push(number)
number += 1
if numbers.length > 3
break
end
end

To pass the challenge you need to break when there are exactly three elements in the array so all you have to do is change your if statement so that it breaks the loop when the array length is greater than or equal to 3. The code below will make it work.
if numbers.length >= 3

numbers = []
number = 0
# write your loop here
loop do
numbers.push(number)
number += 1
if numbers.length > 3
break
else
end
end

8,916 PointsOk, I see the problem. I was pushing to numbers for a 4th time, so the length was 4, not 3. I do think the challenge text is a little confusing though, since it says "greater than 3".
