Binary Tree Inorder Traversal | Javascript Solution
Binary Tree Inorder Traversal is an example of null problems. In this post we will see how we can solve in Javascript.
Problem Description
Given a binary tree, return the inorder traversal of its nodes' values.
For example:
Given binary tree [1,null,2,3],
1
\
2
/
3
return [1,3,2].
Note: Recursive solution is trivial, could you do it iteratively?
