Important questions on bst are posted on the website, now posting the binary tree questions.
Find below question on website.
Write a function that takes in a Binary Tree and returns a list of its branch sums ordered from leftmost branch sum to rightmost branch sum.
A branch sum is the sum of all values in a Binary Tree branch. A Binary Tree branch is a path of nodes in a tree that starts at the root node and ends at any leaf node. Each BinaryTree node has an integer value, a left child node, and a right child node. Children nodes can either be BinaryTree nodes themselves or None / null.

Most Frequently asked interview topics in product based companies :
1. Binary tree
2. Arrays
3. Dynamic Programming
4. Graph
Percent of questions asked varies from company to company.
But if you want to excel interviews then the best way is get hold over recursion.
If you are well versed with recursion you can easily solve above topics.

One of the most loving topics for interviewers is tree.
Many programmers often are unable to solve questions during live interviews, this is due to lack of practice and because of recursion.
Even I was unable to dry run my own code properly.
Almost every beginner finds tree to be a difficult topic because we do not have good command over recursion.
But do not worry, if your interview is aligned up you can quickly revisit the most important concepts and frequently asked questions for technical interview on :
