Pretty rudimentary. And too much code, this is not worthy for a Sr Software Eng.

def one_or_no_parents( data ){
  graph_data = dict()
  for ( pair : data ){
    if ( pair[0] !@ graph_data ){ graph_data[pair[0]] = set() }
    if ( pair[1] !@ graph_data ){ graph_data[pair[1]] = set() }
    graph_data[pair[1]] += pair[0]
  }
  // now parition the whole graph_data 
  parental_buckets = [ set(), set(), set() ]
  for ( child : graph_data.keys ){
    num_parents = size(graph_data[child])
    parental_buckets[num_parents] += child
  }
  [ parental_buckets[0], parental_buckets[1] ] // return 
}
