I need to write a python function that returns the smallest item of a binar tree (t). I need both the iterative and recursive version.

Given Constructor:

def __init__(self,  max_items = 5):
        self.data = []
        self.child = []
        self.max_items = max_items

Starting code:

def smallest(t):

   return 0

Expert Solution
Step 1: Define binary tree

A binary tree is defined as a non-linear data structure of the tree type that has a maximum of two offspring for each parent. In addition to the data element, every node in a binary tree has a left and right reference. The root node is the node at the top of the tree hierarchy.
