Suppose to use an if statement, but it doesn't work with that. Actually, it doesn't work by following the instructions at all. It works with this code though:
words = ['a','b','c','d'] words.each do |words| print words + " " end
There's nothing to redact. No variable is given containing something to be redacted, nor are we told what we're suppose to redact. Basically, the instructions are completely irrelevant.
