03-树3 Tree Traversals Again(25 point(s)) 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 operati…

题目 链接 分析 push是二叉树前序遍历的结果,pop是二叉树中序遍历的结果,所以这个题就是已知前序遍历和中序遍历,求后序遍历. AC代码 #include "bits/stdc++.h" using namespace std; struct TreeNode { int left=-1, right=-1; }tree[45]; vector<int> v; void postorder(int x) { if (x == -1) return; postorder(…

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()…

用栈来模拟一棵二叉树的先序遍历和中序遍历过程,求这棵二叉树的后序遍历 由题棵知道:push是先序遍历 pop是中序遍历 #include<bits/stdc++.h> using namespace std; vector<int>pre; vector<int>in; vector<int>vec; ; int pre1[N]; int in1[N]; void print(int l1,int r1,int l2,int r2) { if(l1>r…
