由于是满二叉树,用数组既可以表示父节点是i,则左孩子是2*i,右孩子是2*i+1另外根据二分搜索树的性质,中序遍历恰好是从小到大排序因此先中序遍历填充节点对应的值,然后再层次遍历输出即可. 又是一道遍历的水题... #include <iostream> #include <cstdio> #include <algorithm> #include <string.h> #include <queue> using namespace std;…

分析: 考察BST + 完全二叉树的性质,注意: (1):先用排序排好,然后由于是完全二叉树,我们使用中序来建树. (2):建好之后,层次遍历可以采用队列. #include <iostream> #include <stdio.h> #include <algorithm> #include <cstring> #include <vector> #include <queue> #include <cmath> usi…

Complete Binary Search Tree PAT-1064 本次因为涉及到完全二叉排序树,所以可以使用数组的形式来存储二叉排序树 对输入序列排序后,得到的是中序遍历二叉排序树的序列.对这颗二叉排序树进行中序遍历,将每个结点的值放入二叉树的存储数组中,最后遍历数组即可求出层次遍历的序列. 此题需要注意层次遍历和数组存储二叉树的关系,利用这个关系可以快速解题. /** * @Author WaleGarrett * @Date 2020/9/5 8:20 */ import java.…
