Given a binary tree, return theinordertraversal of its nodes' values. 示例: 代码语言:javascript 复制 输入:[1,null,2,3]1\2/3输出:[1,3,2] 进阶:递归算法很简单,你可以通过迭代算法完成吗? Follow up: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....

That's all abouthow to implement inOrder traversal of a binary tree in Java using recursion. You can see the code is pretty much similar to the preOrder traversal with the only difference in the order we recursive call the method. In this case, we callinOrder(node.left)first and then ...
