- hosts: localhost
  gather_facts: no
  vars:
    input_file: input
    preamble: 25
  tasks:
    - name: Read program
      set_fact:
        numbers: "{{ lookup('file', input_file).splitlines() | list | map('int') | list }}"
    - name: Bonza
      debug: msg="{{ item }}"
      loop: "{{ numbers[preamble | int:] }}"
      loop_control:
        index_var: idx
      when: item not in numbers[idx:idx + preamble | int] | list | product(numbers[idx:idx + preamble | int] | list) | map('sum') | list
