WIP: script to auto-correct almost any program (the outputs should not contain "\n\n" though)

examinator.rb

## Converting line endings to unix:
inputs_file = File.open('./inputs.txt', 'a+')
outputs_file = File.open('./outputs.txt', 'a+')

input_file_contents = inputs_file.read.gsub(/\r\n?/,"\n")
inputs_file.truncate(0)
inputs_file.print input_file_contents

outputs_file_contents = outputs_file.read.gsub(/\r\n?/,"\n")
outputs_file.truncate(0)
outputs_file.print outputs_file_contents

inputs_file.close
outputs_file.close

#  Getting each input and each output into an array the idea is, basically, 
# separate them each time we find an empty line ("\n").
#  Should be noted though, that since the expected output should contain an
# "\n" at its ending, so should each element on our array.

inputs_file = File.open('./inputs.txt', 'r')
outputs_file = File.open('./outputs.txt', 'r')

inputs = []
outputs = []

# Bug: the last input MAY not contain "\n".
loop do
  inputs_contents = inputs_file.gets('')
  outputs_contents = outputs_file.gets('')
  if inputs_contents.nil? || outputs_contents.nil?
    break
  else
    inputs_contents.gsub!("\n\n", "\n")
    outputs_contents.gsub!("\n\n", "\n")
    inputs << inputs_contents
    outputs << outputs_contents
  end
end

inputs.each { |x| p x}

# To continue. Next step: get user's output.
# Little snippet on how to get terminal's output below:

# test = __FILE__
# puts `ls #{test}`.class # It's a string.

# # snippet on how to get timeout on a faulty code:
# Timeout.timeout(1) { `gcc faulty_code.c < some_input` }
# # => Timeout::Error: execution expired
