Re: assert_equal ([:r, :u, :b, :e, :q, :u, :e] __), [:b, :q]

Hey David,

Perhaps it has to do with certain operations that you can do with arrays in
Ruby ... Remember that Ruby provides syntactic sugar for certain kinds of
methods ... So, for e.g

def name= (name)
  @name = name
end

can be invoked as

<some_object>.name = "David"

What Ruby does here is that it sees an assignment (name = "David") and
looks for a method called name= (Note there is no whitespace between name
and "=").

I bring this up b/c it seems that you are thinking of a method that you
could use here ("I don't understand the above because the blank is not
right up against
the .. array"). And the solution lies in invoking a method on an array, but
with the syntactic sugar applied.

Look at http://www.ruby-doc.org/core-1.9.3/Array.html and look at any
mathematical operators that might come in handy - see how they are to be
used.

Hope that helps.
