When it is required to find the count of the non leaf nodes in a Tree, a ‘Tree_structure’ class is created, methods to set a root value, and to add other values are defined. Various options are given that the user can select. Based on the user’s choice, the operation is performed on the Tree elements.Below is a demonstration of the same −Example Live Democlass Tree_structure: def __init__(self, data=None): self.key = data self.children = [] def set_root(self, data): self.key = data def add_vals(self, node): ...
