What is the best way to get determine the largest and smallest int in an  
array of ints? For example:

x = [1,2,3,4]

x.smallest should = 1  
x.largest should = 4

How is this done in Ruby?

Thank you,  
Brad

puts x.max  
puts x.min

See the documentation for Enumerable (try “ri Enumerable” at your  
prompt).
