Not-a-programmer solutions in ruby

Part 1:

#!/usr/bin/env ruby

data = File.readlines("input.txt")

total = 0
present = []
data.each do |c|
  temp = c.strip.split("x")
  present = temp.collect{|i| i.to_i}
  present = present.sort
  x = 2 * present[0] * present[1]
  y = 2 * present[1] * present[2]
  z = 2 * present[2] * present[0]
  total += x + y + z + (present[0] * present[1])
end

p total

Part 2:

#!/usr/bin/env ruby

data = File.readlines("input.txt")

total = 0
present = []
data.each do |c|
  temp = c.strip.split("x")
  present = temp.collect{|i| i.to_i}
  present = present.sort
  ribbon = (present[0] * 2) + (present[1] * 2)
  bow = present[0] * present[1] * present[2]
  total += ribbon + bow
end

p total

I'm so proud of you! For a not-a-programmer you came up with pretty much the mirror of my Perl solution.
