If you just want to select the elements that meet some condition, use one
of the following Array methods:
keep_if <http://ruby-doc.org/core-2.0/Array.html#method-i-keep_if>
select <http://ruby-doc.org/core-2.0/Array.html#method-i-select>
reject <http://ruby-doc.org/core-2.0/Array.html#method-i-reject>
