This is the most difficult of all types of iterative tree traversals. You should attempt this problem:Binary Search Tree In-Order Traversal Iterative Solutionbefore this as it is an easier problem. The easiest of all iterative tree traversals isPre-Order Traversal. Post-order traversal is useful ...
Postorder与Inorder很相似,但是比Inorder复杂的地方是如何判断该节点的左右子树都已经访问过了,按照Inorder的写法左子树还是先被访问,没有问题,但是访问完左子树后不能直接访问当前节点,要判断当前节点的右子树是否已经被访问,如果没有访问则应该继续去访问右子树,最后再访问当前节点 1vector<int> postorderTraversal(T...
