loop. The same way an array is continuously broken and half and searched for a binary search, traversing a tree requires breaking a large tree into smaller trees. 2. Binary trees are only efficient when they are balanced. A balanced binary tree can be searched quickly, with growth of O(log n). If the tree is unbalanced, it can become similar to a linked list, which has a search growth of O(n). Inserting elements in binary trees requires similar operations no matter what type it is, and are similar

因此输出为该子数组的和18。 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 ------------------------------------

order. 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

Linked List MCQ Misc Output String Tree Graph A program to check if a binary tree is BST or not A binary search tree (BST) is a node based binary tree data structure which has the following properties. • The left subtree of a node contains only nodes with keys less than the node’s key. • The right subtree of a node contains only nodes with keys greater than the node’s key. • Both the left and right subtrees must also be binary search trees. From the above properties it naturally follows that:
