aws sdk – Converting output of one function into array and feed value into variable in other function in ruby

For one of ruby programming logic, am trying to convert the string output of one function into an array and from array have to feed the values to the variables declared in other function of the program

//response.each do |instance |
  print "#{instance.private_ip_address}"
  print "n"
  end
//

10.1.1.1
10.1.1.2
10.1.1.3

This output should be converted into array and feed as values in separate function of same program

def run_me
    ::
    ::
    filter_pattern = '[w1,w2,w3,w4,w5,w6!="*#{array[0]}*"&&w6!="*#{array[1]}*&&w6!="*#{array[2]}*"]'

So that the output of filter_pattern , should be like below

   '[w1,w2,w3,w4,w5,w6!="*10.1.1.1*"&&w6!="*10.1.1.2*"&&w6!="*10.1.1.3*"]'
