I am not getting any output:
can any one point me by saying where did I wrong?
ar = [1,2,3,1,5,3,"a","b","c"]
e = ar.each_slice(3)
e.size.times{|i| i = e.next; p i if (e.peek rescue StopIteration) == nil
}
I want the output: ["a","b","c"] but getting
nothing.

Here I have done:
ar = [1,2,3,1,5,3,"a","b","c"]
e = ar.each_slice(3)
e.size.times{|i| i = e.next;p i if !(e.peek rescue nil) }
#=> ["a", "b", "c"]
