Question 1) Describe a B-Tree implementation When databases are used with a pointer s there is an indexing technique called a B-Tree. Within this B-Tree structure all references to the data within as well as that can be accessed. That is why data can be deleted easier and faster. At the bottom of the B-Tree is what is referred to as a node and the root is located on the top. The only way I can explain this, is by using a figure we all see every day. Look at a tree upside down, that is what

Matthew Hendrickson Tree Lab Questions 1. Recursive algorithms work well for trees because recursion allows for storing areas that have been traversed on the system stack, so that all avenues can be explored. Similar to the maze example from the chapter on recursion. Recursion also works well when the same steps have to be repeated on different parts of a data structure and is often simpler and more elegant than iteration with a loop. The same way an array is continuously broken and half and

4.在二元树中找出和为某一值的所有路径 题目： 输入一个整数和一棵二元树。 从树的根结点开始往下访问一直到叶结点所经过的所有结点形成一条路径。 打印出和与输入整数相等的所有路径。 例如 输入整数22和如下二元树 10 / \ 5 12 / \ 4 7 则打印出两条路径：10, 12和10, 5, 7。 二元树节点的数据结构定义为： struct BinaryTreeNode // a node in the binary tree { int m_nValue; // value of node BinaryTreeNode *m_pLeft; // left child of node BinaryTreeNode *m_pRight; // right child of node }; 5.查找最小的k个元素 题目：输入n个整数，输出其中最小的k个。 例如输入1，2，3，4，5，6，7和8这8个数字，则最小的4个数字为1，2，3和4。 第6题 ------------------------------------

There are a number of different sorting algorithms; a programmer would choose which one to use depending on the amount and type of data being sorted. Insertion sort, Bubble sort, and Selection sort are described with examples. Phase 4 A binary tree, is a node-based data structure where each node has a comparable key (and an associated value) and satisfies the restriction that the key in any node is larger than the keys in all nodes in that node's left subtree and smaller than the keys in all

CS 106B: Programming Abstractions in C++ Course Syllabus Stanford University Autumn 2013 This is a tentative syllabus for CS 106B. All readings come from the Programming Abstractions in C++ textbook. Each unit is roughly 3-4 lectures in length. Near the end of each unit a corresponding homework assignment will be given. De pending on how quickly we finish material, we may end up spending more or less time on each topic. Readings are highly recommended but are not directly evaluated; for example
