B-Tree(这儿可不是减号,就是常规意义的BTree) 是一种多路搜索树: 1.定义任意非叶子结点最多只有M个儿子:且M>2: 2.根结点的儿子数为[2, M]: 3.除根结点以外的非叶子结点的儿子数为[M/2, M]: 4.每个结点存放至少M/2-1(取上整)和至多M-1个关键字:(至少2个关键字) 5.非叶子结点的关键字个数=指向儿子的指针个数-1: 6.非叶子结点的关键字:K[1], K[2], …, K[M-1]:且K[i] < K[i+1]: 7.非叶子结点的指针:P[1], P[…

[BZOJ3282]Tree (Link-Cut Tree) 题面 BZOJ权限题呀,良心luogu上有 题解 Link-Cut Tree班子提 最近因为NOIP考炸了 学科也炸了 时间显然没有 以后再来填LCT的坑 这种题目直接上代码了.. #include<iostream> #include<cstdio> #include<cstdlib> #include<cstring> #include<cmath> #include<alg…

Design an algorithm to encode an N-ary tree into a binary tree and decode the binary tree to get the original N-ary tree. An N-ary tree is a rooted tree in which each node has no more than N children. Similarly, a binary tree is a rooted tree in whic…

平衡二叉树(Balanced Binary Tree 或 Height-Balanced Tree)又称AVL树 (a)和(b)都是排序二叉树,但是查找(b)的93节点就需要查找6次,查找(a)的93节点就需要查找3次,所以(b)的效率不高. 平衡二叉树(Balanced Binary Tree 或 Height-Balanced Tree)又称AVL树.它或者是一颗空树,或者是具有下列性质的二叉树:它的左子树和右子树的深度只差的绝对值不超过1.若将二叉树上节点的平衡因子BF(Balance F…

1.Visual Tree和Logical TreeLogical Tree:逻辑树,WPF中用户界面有一个对象树构建而成,这棵树叫做逻辑树,元素的声明分层结构形成了所谓的逻辑树!!Visual Tree:可视树(也叫视觉树),可视树是对逻辑树的扩展,可视树将逻辑树的节点打散,分放到核心棵树组件中,它表述了一些详细的可视化实现,而不是把每个元素当做一个”黑盒“.我们以一个简单的程序来观察下逻辑树与可视树: <Window x:Class="WpfApplication28.MainWind…

议题:TRIE树 (Trie Tree or Prefix Tree): 分析: 又称字典树或者前缀树,一种用于快速检索的多叉树结构:英文字母的Trie树为26叉树,数字的Trie树为10叉树:All the descendants of a node have a common prefix of the sequence associated with that node, and the root is associated with the empty sequence. 由于不同的se…

1.二叉搜索树:去一个陌生的城市问路到目的地: for each node, all elements in its left subtree are less-or-equal to the node (<=), and all the elements in its right subtree are greater than the node (>). 给予一个已经排序好的整数数组, 生成一个相对合理的二叉搜索树.(?相对合理的?) 给予一个二叉树的根节点,验证该树是否是二叉树搜索树,(…
