清华大学类数据结构实现的乙
清华大学数据结构课上实现的B+树,设计一个4阶B+树,包括: (1) 叶子的每个记录应该包括4字节(long)关键码值和60字节的数据字段(存储文件名等,可以自定),设每个叶子可以存储5条记录,而内部节点应该是关键码值/指针对。此外,每个节点还应该有指向同层下一个节点的指针、本节点存储的关键码数等; (2) 此4阶B+树应该支持插入、删除以及根据给定关键码值进行精确检索与关键码范围检索; (3) 显示(打印)此4阶B+树的生长(含删除节点)过程实例;-Tsinghua University class data structure to achieve the B-tree, the design of a B-tree four bands, including : (a) the leaves of each record should include 4-byte (long) key code value and 60 gigabytes of data fields (document storage, etc., can be set), set up each leaf store five records, and internal nodes is the key code value/means against. In addition, each node should have the same point under a layer of the target node, the node storage key code number; (2) The B-tree four bands should support the insertion, deletion and with the given key code value accurate retrieval and key codes scope retrieval; (3) Display (Print ) This four bands B-tree growth (including the deletion of nodes) process examples;

二叉树与二叉链表
假设以如下说明的三元组 (F、C、L/R) 序列输入一棵二叉树的诸边(其中 F 表示双亲结点的标识,C 表示孩子结点标识,L/R 表示 C 为 F 的左孩子或右孩子),且在输入的三元组序列中,C 是按层次顺序出现的。设结点的标识是字符类型。F=‘^’时 C 为根结点标识,若 C 亦为‘^’,则表示输入结束。试编写算法,由输入的三元组序列建立二叉树的二叉链表,并以中序序列输出。^AL ABL ACR BDL CEL CFR DGR FHL ^^L -Assuming the following description of the triple (F, C, L/R) sequence of a binary tree of all the input side (where F that identifies the parent node, C, said child node ID, L/R that C is F, left or right child child), and triples in the input sequence, C is the emergence of a hierarchical order. Node identity is established character types. F = " ^" C for the root identity when, if C is also a " ^" , then enter the end. Test preparation algorithm, the input sequence of triples binary build the binary tree list, and in order to sequence the output
