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…
内存池技术就是创建一个内存池,内存池中保存着可以使用的内存,可以使用数组的形式实现,然后创建一个空闲列表,开始时将内存池中所有内存放入空闲列表中,表示空闲列表中所有内存都可以使用,当不需要某一内存时,将其放入空闲列表中,使内存可以循环使用.空闲列表可以用不定长数组vector定义,内存池和空闲列表的类型由使用内存的数据决定,如果使用内存的数据是用户自定义的结构体类型,则使用此类型.由于大部分情况下是使用指针进行内存调用,所以空闲列表中存储的是相应的指针. 具体实例如下: 题目: Trees ar…

Given a binary tree, return the bottom-up level order traversal of its nodes' values. (ie, from left to right, level by level from leaf to root). For example:Given binary tree [3,9,20,null,null,15,7], 3 / \ 9 20 / \ 15 7 return its bottom-up level or…

Given a binary tree, return the zigzag level order traversal of its nodes' values. (ie, from left to right, then right to left for the next level and alternate between). For example:Given binary tree [3,9,20,null,null,15,7], 3 / \ 9 20 / \ 15 7 retur…
