Ruby Challenge: Dream_slice

---

Task Details:

Execute the code against the input file (somefile.txt).
The expected output results are below.

Over and over again
I relive the moment
I am bearing the burden within
Open wounds hidden under my skin

Pain is real as a cut that bleeds
The face I see every time I try to sleep
Staring at me crying

Dream_slice Challenge Solution

output = ""

for arg in ARGV
   file = File.open(arg)

   file_data = file.read

   file_data.each_line do |line|

     line_order = line.split(" ").map(&:to_s).rotate(1)

     line_order.each do |word|

       char_order = []

       if word.size == 1

         output += word.concat(" ")
       elsif word.size == 2
         order = [1,0]

         output += order.map{|x| word[x]}.join().concat(" ")
       elsif word.size == 3
         order = [1,0,2]

         output += order.map{|x| word[x]}.join().concat(" ")
       elsif word.size == 4
         order = [1,0,3,2]

         output += order.map{|x| word[x]}.join().concat(" ")
       elsif word.size == 5
         order = [3,4,2,0,1]

         output += order.map{|x| word[x]}.join().concat(" ")
       elsif word.size == 6
         order = [1,0,3,2,5,4]

         output += order.map{|x| word[x]}.join().concat(" ")
       elsif word.size == 7
         order = [2,3,5,6,4,0,1]

         output += order.map{|x| word[x]}.join().concat(" ")
       else

       end

     end

     output += "\n"
   end

   puts output.gsub!(" \n\n","\n \n").gsub!(" \n","\n").strip
end

Solution Notes:

Resets the character order variable for ever loop iteration of each word.
