This is part of a online ruby quiz. Just doing it for my own
education, not on a test that I'm graded on.
assert_equal ([:r, :u, :b, :e, :q, :u, :e] __), [:b, :q]
I don't understand the above because the blank is not right up against
the [:r, :u, :b, :e, :q, :u, :e] array. I'm not sure how to search
for whatever is supposed to be in the blank.
If someone could give me a hint rather than an answer it would be appreciated.

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 Class: Array (Ruby 1.9.3) and look at any
mathematical operators that might come in handy - see how they are to be
used.
Hope that helps.

Just the kind of pointer I was hoping for. Thanks.
