Use the graph classes DAG, Node and Arc that we developed in the lectures, as summarized below: Make the following modifications: 1. Add object variables "successor_nodes" and "predecessor_nodes" to the Node class as lists. 2. Write function "initialize_pred_succ_nodes" in class DAG which fills these lists as intended by their names using lists "nodes" and "arcs FEBRER class Node : def _init__(self, code: str) -> None: self.code = code class Arc: def _init__(self, from_node: Node, to_node: Node, distance: int) -> None: self.from_node = from_node self.to node = to node self.distance = distance class DAG: def init__(self) -> None: self.nodes = [] self.arcs = []
