DATA RECOVERY(CodeEval)

CHALLENGE DESCRIPTION

Your friends decided to make a fun of you. They've installed a script to your
 computer which shuffled all of the words within a text. It was a joke, so they've
 left hints for each sentence which allow you to easily rebuild your data. 
The challenge is to write a program which reconstructs each sentence out of a set
 of words, you need to find out how to use a given hint and print out the original
 sentences.

INPUT SAMPLE

Your program should accept as its first argument a path to a filename. Each line
 is a test case. Each test case consists of a set of words and a sequence of
 numbers separated by a semicolon. The words within a set and the numbers
 within a sequence are separated by a single whitespace. E.g.
2000 and was not However, implemented 1998 it until;9 8 3 4 1 5 7 2
programming first The language;3 2 1
programs Manchester The written ran Mark 1952 1 in Autocode from;6 2 1 7 5 3 11 4 8 9

OUTPUT SAMPLE

For each test case print out the reconstructed sentence one per line. E.g.

However, it was not implemented until 1998 and 2000
The first programming language
The Manchester Mark 1 ran programs written in Autocode from 1952

Constraints:
The number of test cases is in range [20, 40].
The words consist of ASCII upper and lower case letters, digits and punctuation.

My code

#!/usr/bin/env ruby
def data_recovery(words, orders)
  orders = orders.map(&:to_i)
  lack_of_order = ((1..words.size).to_a - orders)
  orders += lack_of_order
  # ruby 2.1
  # Hash[orders.zip words].sort.to_h.values.join(' ')
  Hash[Hash[orders.zip words].sort].values.join(' ')
end

ARGF.each_line do |line|
  puts data_recovery(*(line.chomp.split(';').map(&:split)))
end
