题意:给你一些字符串,代表某个值被插入树中的位置.让你输出层序遍历. 题解:动态建树. 由于输入复杂,将输入封装成read_input.注意输入函数返回的情况 再将申请新节点封装成newnode(). 最后层序输出直接用bfs实现. 坑:我把ans.clear放到主程序的if里面,导致某特定情况无法初始化,wa了一页//以后debug真的别XJB改细节了上下语句顺序,一些无关紧要的处理,改之前想一想 #define _CRT_SECURE_NO_WARNINGS #include "stdio.…
题目链接:https://vjudge.net/problem/UVA-122 题目大意:输入一颗二叉树,你的任务是按从上到下,从左到右的顺序输出各个结点的值.每个结点都按照从根节点到它的移动序列给出(L表示左,R表示右) 在输入中,每个结点的左括号 和右括号之间没有空格,相邻结点之间用一个空格隔开.每棵树的输入用一对空括号)()结束  入上图所示: 注意:如果从根结点到某个叶节点的路径有的结点没有在输入中给出,或者给出超过一次,输出not complete.  结点个数不超过256 思路:显然…
 Trees on the level UVA - 122  解题思路: 首先要解决读数据问题,根据题意,当输入为“()”时,结束该组数据读入,当没有字符串时,整个输入结束.因此可以专门编写一个readin()函数,类型设置为bool型,遇到第一种情况时返回true,遇到第二种情况返回false,主程序中只要发现readin返回false时就break,结束整个大循环. 接下来要建立二叉树,首先为二叉树编写一个结构体,然后根据字符串的输入情况来建树,如果是‘L’就往左走,走不动时建一颗新树,同样…

/** 题目:Trees in a Wood. UVA 10214 链接:https://vjudge.net/problem/UVA-10214 题意:给定a,b求 |x|<=a, |y|<=b这个范围内的所有整点不包括原点都种一棵树.求出你站在原点向四周看到的树的数量/总的树的数量的值. 思路: 坐标轴上结果为4,其他四个象限和第一个象限看到的数量一样.所以求出x在[1,a]和y在[1,b]的x/y互质对数即可. 由于a比较小,所以枚举x,然后求每一个x与[1,b]的互质对数. 方法: 1…
