The Falling Leaves UVA - 699 Each year, fall in the North Central region is accompanied by the brilliant colors of the leaves on the trees, followed quickly by the falling leaves accumulating under the trees. If the same thing happened to binary trees,
题意： 有一颗n个叶子的无权树，输入两两叶子的距离，恢复出这棵树并输出每个非叶子节点的度数。 思路： 参考：https://blog.csdn.net/zju2016/article/details/78450509 无根树，现将一个叶子节点作为根。逐个探测剩下的叶子节点，并在这个过程中不断增加内部节点以满足其距离要求，最终建
A family hierarchy is usually presented by a pedigree tree. Your job is to count those family members who have no child. Input Specification: Each input file contains one test case. Each case starts with a line containing 0, the number of nodes in a tree,
我的解析 1、他们已经到了。（语境：所以，放心吧… / 所以，你不用过去了/ 所以, … 【我的翻译】They have already arrived. 【标准答案】They have already arrived. 【解题思路】看这个语境应该用现在完成时, 对现在有影响 - 内部关系：动作关系 - 句

03-树2 List Leaves（25 分) Given a tree, you are supposed to list all the leaves in the order of top down, and left to right. Input Specification: Each input file contains one test case. For each case, the first line gives a positive integer N(≤10)N (≤10
一种新的不使用左右子树递归进行树高计算的方法，使用层次遍历 树的存储方式： 1.本题提供的一种思路： 使用（邻接表的思想）二维数组（vector[n]）表示树，横坐标表示 父节点，每一行表示孩子。 能够很轻松的使用dfs进行遍历 优点： 只需要知道输入的父和子的值，不需要清楚整个树的结构， 能够方便的使用
Each year, fall in the North Central region is accompanied by the brilliant colors of the leaves on the trees, followed quickly by the falling leaves accumulating under the trees. If the same thing happened to binary trees, how large would the piles of le
1、题目描述 2、问题分析 对于每个节点，如果其左子节点是叶子，则加上它的值，如果不是，递归，再对右子节点递归即可。 3、代码 1 int sumOfLeftLeaves(TreeNode* root) { 2 if (root == NULL) 3 return 0; 4 int ans = 0; 5 if (root->left !=
