Mutable Trees Tree Class class Tree: def __init__(self, label, branches=[]): for b in branches: assert isinstance(b. Tree) self. label = label self, branches branches def is lear(self) return not self branches For each question below, you will be shown a selector/constructor using the Abstract Data Type definition for a tree t. Imagine t was instead an object based tree. Write the equivalent selector constructor usage using the object based tree implementation. label(t) * 1 point Your answer is_leaf(t) * 1 point Your answer tree(1. [tree(2), tree(3)]) * 1 point Your answer branches(t) 1 point Your
