I found for some types of large sorts, I have better luck breaking =

class Map <

b =3D %w[a1 a3 a2 a4 a7 a6 a5 a8 a9 a10]

storage =3D Array.new

b.each do |item|

  a_char =3D Map.new

  item_alpha =3D item.split(/\d/)
  a_char.char_alpha =3D item_alpha

  item_number =3D item.split(/\D/)
  a_char.char_numb =3D item_number[1].to_i   # convert to integer for =
sort

  storage.push(a_char)

end
 b.clear    # remove contents of old array

storage.sort_by! { |a| [a.char_alpha, a.char_numb]}  # sorting order =
performed here first by alpha then numeric

storage.each do |f|             # build new array for b sorted correctly

  tmp_item =3D f.char_alpha[0] + f.char_numb.to_s
  b.push(tmp_item)

end

The cool thing is you can now do all kinds of multi sorts using this =
type of arrangement. Comes in handy where you have to sort multiple =
arrays and then merge those results at the end.=20
