094.binary-tree-inorder-traversal 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?
The node is visited after the In-order Traversal of the left subtree, and before the In-order Traversal of the right subtree.This is how the code for In-order Traversal looks like:Example Python: def inOrderTraversal(node): if node is None: return inOrderTraversal(node.left) print(node....
