题目见这里 分析:分四步进行 1)根据给定的结点情况建二叉树  2)对输入的键值排序(asending) 3)对二叉树中序遍历,同时对应赋key值 4)层次遍历(队列应用) 题目并不困难,但是我误入了trick,错误假定了结点按先序遍历是按顺序编号的(当然是受样例的影响),所以有了下面22分(满分30)   的submit(贴出来是因为这不失为好的巩固二叉树知识的程序) #include <stdio.h> #include <stdlib.h> //qsort,malloc #d…

Build A Binary Search Tree PAT-1099 本题有意思的一个点就是:题目已经给出了一颗排序二叉树的结构,需要根据这个结构和中序遍历序列重构一棵二叉排序树. 解法:可以根据中序遍历的思路,首先将给定的序列串进行排序即是中序遍历的结果.接着,根据给定的树结构进行中序遍历,这期间就可以确定每个结点的值.最后,只需要根据这棵树就能进行层次遍历了. 题目具备一些难度,需要一些思维能力和扩展能力. import java.util.ArrayList; import java.u…
