The Quick Union implementation assumes that the root nodes are assigned a parent ID of “-1". If I wanted to change this and set root nodes to have a parent ID of "0" instead of “-1", which lines in the following code would change? Select all that should change. 1 class QuickUnion: 2 def init (self, size: int) -> None: CHOICES (Select all that may apply.) 4 size: number of elements to initialize self.size = size a. None of the above 7 self.parent = [-1]*self.size b. Line 16 8 c. Line 15 str_(self) -> str: return f"parent: {self.parent}" def 10 d. Line 26 11 e. Line 20 def get_root(self, p: int) -> int: *"Find the root of p""" idx = p 12 13 f. Line 7 14 while self.parent[idx] >= 0: idx = self.parent[idx] return idx 15 16 17 18 def is connected(self, pl: int, p2:int) -> bool: return self.get_root(p1) == self.get_root(p2) 19 20 21 def connect(self, pl: int, p2: int) -> None: "*"Connects pl and p2""" rl = self.get_root(pl) r2 = self.get_root(p2) self.parent[rl] = r2 22 23 24 25 26
