I’m stuck finding the path of the given node so I can find the right side but not the left side. For example, when I search for 5 in X=”+ * + 5 7 4 1 6″, the output is like [‘+’, ‘*’, ‘+’, ‘5’] but when I try to search for any number on the lift subtree, it gives

Find root to leaf path with given sum. Code succeeds with string, fails with list
I am looking at a binary tree problem. The goal is to find all path(s) from root to leaf, such that the values on the path sum up to a given k. For that purpose I have written the same algorithm in two different ways: The first version uses a string parameter a. The second version uses a list parameter
Covert Binary Tree to Doubly Linked List (Microsoft Interview)
We are converting a binary tree into a DLL, in place also we are using in order traversalto do so. Read more here – Link My Code: My problem: The head is always None and hence I cannot print the converted list. What is wrong with this code or my logic? Answer Your code has many Pitfalls, the main reason
Is it a mandatory to have two classes(Node,Tree) while implementing a binary tree?
This may sound silly but trust me , I have searched for various articles online and could not find a proper explanation or no explanation at all , Does it really need two classes one for Node and one for tree to implement binary tree? for Instance , let’s take a simple python code : this is bascially which I
How to create a Binary Tree in Python?
Hi, I have tried to create a Binary Tree above but I did not managed to print out the binary tree when I print “t”. Instead of a Binary Tree, it shows me this: Answer Function t just creates a binary tree. If you want to print a tree you need to traverse it and print it. Depending on the
Python – Tree without classes
How can I implement a tree without using classes in python? I can only use lists, dictionaries and queue. Obviously without the library bintree. Answer I usually use defaultdict: Usage: bonus: Maria Callas singing O Mio Babbino Caro
