6-11 Level-order Traversal(25 分) Write a routine to list out the nodes of a binary tree in "level-order". List the root, then nodes at depth 1, followed by nodes at depth 2, and so on. You must do this in linear time. voidLevel_order( Tree T,void(*visit)(Tree ThisNode) )...
层序遍历(Level Order Traversal) 从上到下,从左到右,一层一层访问 计算二叉树高度、判断一棵树是否为完全二叉树 funcLevelOrderTraversal(){// 通过队列来实现,按层入队,节点出队,对应的子节点入队letqueue=NSMutableArray.init()vartempNote:Notequeue.add(root!)// 遍历,如果下一层还有元素,那就继续遍历whi...
中序遍历(InOrder Traversal) 后序遍历(PostOrder Traversal) 层序遍历(Level Order Traveral) 不管是什么二叉树,这四种遍历的代码都是统一的。 4.3.1 前序遍历(PreOrder Traversal)——递归 节点访问顺序:根节点、前序遍历左子树、前序遍历右子树 // 前序遍历publicvoidpreOrederTraversal(Node<E> root){if(roo...

1.Divide the given problem instance into smaller instances. 2.Solve the smaller instances recursively. 3.Combine the smaller solutions to solve the original instance. • This works best when the smaller instances can be made to be of equal (or near-equal) size.最好的情况是实例被平分 ...
