I'm looking for a method that takes an array and returns its elements  
grouped together in arrays of length 2, with the array at the very end  
having a length of 1 or two.

For example:  
group [1,2,3,4,5,6] #=\> [[1,2],[3,4],[5,6]]  
group ['f','o','o'] #=\> [['f','o'],['o']]

def group(ary)  
&nbsp;&nbsp;ary.each\_slice(2).to\_a  
end
