I'm not positive what you are trying to do here.  However from the code you
have posted i never changes so you will continuously overwrite
faulty_line[i] and correct_line[i].

If you are trying to correlate line numbers with line data maybe a hash
would be better?  For example:

array_of_errors         # this would be an array
error_line_numbers   # this would be an array

errors = {}

error_line_numbers.each do |line_number|
  errors[line_number.to_sym] = array_of_errors[line_number]
end

of course this also assumes a one to one mapping of the line_number and
line_data arrays.
