Question

I am to write a python function to find the number of children each node in a binary tree has. (t) being the root of the binary tree and (k) being the node that the function counts the children. return -1 if (k) is not in (t). 

Starting code:

def num_children(t,k):

x = t.find(k)

 

   return 1

Expert Solution
Step 1: introduction :

To find the number of children each node in a binary tree has, you can use a recursive approach. You can start from the root of the tree and traverse the tree to find the node k. Once you find k, you can count its children (left child and right child). If k is not found in the tree, you return -1.
