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-m= ax_by

words =3D [
=A0 'a',
=A0 'abc',
=A0 'abcde',
=A0 'ab'
]
puts words.max_by &:length
