03-树3 Tree Traversals Again 这道题我的思路是先根据输入得到先序和中序遍历的序列,最后用递归方式构造好树并进行遍历输出。事实上仅该题要求而言无需构造出二叉树再对树本身进行遍历,只需要知道先序和中序的序列,根据关系递归找出后序序列即可,网上方法也多是这种。而我当时一心想着就要用已知的两个序列把这颗...
An inorder binary tree traversal can be implemented in a non-recursive way with a stack. For example, suppose that when a 6-node binary tree (with the keys numbered from 1 to 6) is traversed, the stack operations are: push(1); push(2); push(3); pop(); pop(); push(4); pop(...

Each input file contains one test case. For each case, the first line contains a positive integer N (≤30) which is the total number of nodes in a tree (and hence the nodes are numbered from 1 to N). Then 2N lines follow, each describes a stack operation in the format: "Push X"...
