Hi,

This is not a homework forum. Apart from that, your description is far 
too vague to make anything useful out of it. Procs are just a tool, you 
can use them in all kinds of ways. So saying "find the word using a 
proc" is like saying "sort an array using methods".

The usual solution to "get the smallest/biggest value" is to use the 
method Enumerable#max_by (or min_by):

http://ruby-doc.org/core-1.9.3/Enumerable.html#method-i-max_by

words = [
  'a',
  'abc',
  'abcde',
  'ab'
]
puts words.max_by &:length
