I keep getting this error message when I do the task, and it displays the correct output on the console and also a list of bugs? (Like actual bugs like cockroaches, not computer bugs?)

“It looks like your method doesn’t default to alphabetizing an array when it doesn’t receive a second parameter.”

This keeps happening to me too!

Welcome to the forums, @dev3770248477. Would you be good enough to share your code with us? I don’t seem to be getting any of the errors brought up here. It would help clear the air for this particular issue if we could read the code.

This was the solution which was offered to me, after a lot of trying…

def alphabetize(arr, rev = false)

arr.sort!

end

numbers = [3, 5, 1, 6]

puts alphabetize(numbers)

I was getting the same error and the array of bug names. Here’s what I had-

def alphabetize(arr, rev = false)

puts arr.sort!

end

numbers = [2, 4, 3, 1]

alphabetize(numbers)

I removed puts from the method and called it when I called alphabetize at the bottom. Worked but I’m not sure why.

Ruby implicitly returns the last line of a method. In the first example it will print the sorted array and return Nil. In the second example it will return the array which can then be printed at the caller.
