[题意] 给定一棵树每个结点的权重和路径(路径用LR串表示),输出这棵树的层次遍历 [思路] 注意输入输出,sscanf用来格式化地截取需要的数据,strchr来在字符串中查找字符的位置 [Accepted] #include<iostream> #include<cstdio> #include<string> #include<cstring> #include<algorithm> #include<queue> using n…

紫书上的原题 正好学数据结构拿出来做一下 不知道为什么bfs的队列一定要数组模拟…… 还可以练习一下sscanf…… #include<stdio.h> #include<iostream> #include<algorithm> #include<math.h> #include<string.h> #include<string> #include<map> #include<set> #include&l…

Trees are fundamental in many branches of computer science (Pun definitely intended). Current state- of-the art parallel computers such are based on fat trees . Quad- and octal-trees are fundamental to many algorithms in computer graphics. This probl…

 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…

题目如下:Given a sequence of binary trees, you are to write a program that prints a level-order traversal of each tree. In this problem each node of a binary tree contains a positive integer and all binary trees have have fewer than 256 nodes. In a level…
