Hi, I'm CFC
I'm new at here.
Nice to meet you:)

I just coded an extension for Array.
It will return the longest element of an array.
Source:

class Array
  def which_long?
    # Version 1.0
    # Coded by CFC < zusocfc @ gmail . com >
    # PLEASE DO NOT REMOVE THE COMMENT OF THIS FUNCTION, THANKS A LOT.
    # Usage:
    #   ['a', 'ab', 'abc' 1234].which_long?
    #   => 1234
    max, long, self_cpy = 0, "", []
    self.size.times{|i| self_cpy << self[i].to_s}
    self_cpy.each{|item| (max = item.size; long = item) if item.size > max }
    long
  end
end

Usage:
  puts [1, 23, '456'].which_long?
  => 456
