1 Binary Trees COMPSCI 355 Fall 2016
2 Graphs A graph consists of objects called nodes and a binary relation defined on nodes. A B D E C G F
3 Graphs A path is a sequence of nodes connected by edges. A B PATH: AGFBC D E C G F
4 Trees A tree is a connected graph with no cycles. A B Not a tree. Why not? D E C G F
5 Trees A tree is a connected graph with no cycles. A B D E C G F
6 Trees A tree is a connected graph with no cycles. A B Can you define trees in terms of paths between nodes? D E C G F
7 Trees By tree, we usually mean a rooted tree. A B There is a distinguished node called the root. D E C G F
8 Trees By tree, we usually mean a rooted tree. A B A D E C D B G G F C E F

11 Terminology Ancestors of a node X: any node on a path from X to the root. Descendants of a node X: any node of which X is an ancestor. Leaf (external node): a node with no descendants. B F C G A K D E H I J L N M ancestors of node N
12 Terminology Depth of a node: length of the path to the root. Height of a node: maximum length of a path to a leaf. B F C G A E D H I J Height of a tree: the height of its root. K L N M
13 Terminology Child of a node: descendent at the next level. Parent of a node: ancestor at the previous level. B F C G A E D H I J Siblings: nodes with the same parent. K L N M
14 Binary Trees Every node has at most two children. Number of nodes in a binary tree is at most 2 h+1 1.
15 Binary Trees Every node has at most two children. class Node { public: private: int key; Node* left; Node* right; };
16 Binary Search Trees Each node's key is greater than or equal to all keys in its left subtree, and smaller than all keys in its right subtree If the tree is balanced then we have logarithmic-time searches, insertions, and deletions.
17 Binary Search Trees Each node's key is greater than or equal to all keys in its left subtree, and smaller than all keys in its right subtree Node bst_search(node* p, int key) { } if (p == null) return null; if (key < p->key) return bst_search(p left, key); if (key > p->key) return bst_search(p right, key); return p;
18 Binary Search Trees Each node's key is greater than or equal to all keys in its left subtree, and smaller than all keys in its right subtree Node bst_search(node* p, int key) { } while (p!= null) { if (key == p->key) return p; if (key < p->key) p = p->left; else p = p->right; } return null;
19 Preorder Traversal 1. visit root 2. traverse left subtree in preorder 3. traverse right subtree in preorder void preorder_traverse(node* p) { } if (p == null) return; cout << p->key << endl; preorder_traverse(p->left); preorder_traverse(p->right);
20 Preorder Traversal 1. visit root 2. traverse left subtree in preorder 3. traverse right subtree in preorder void preorder_traverse(node* p) { } Stack<Node*> s; s.push(p) while (!s.empty()) { Node* q = s.pop() } cout << q->data << endl; if (q->right!= null) s.push(q->right); if (q->left!= null) s.push(q->left);
21 Other Traversals 63 In-Order Traversal 1. traverse left subtree in in-order 2. visit root 3. traverse right subtree in in-order Post-order Traversal 1. traverse left subtree in post-order 2. traverse right subtree in post-order 3. visit root
22 Application Representing arithmetic expressions. + a * b / Used in most compilers. Can speed up computation if intermediate values are known. c d a + (b * (c / d))
23 Application Representing arithmetic expressions. + Pre-order: + a * b / c d a * b / In-order: a + b * c / d Post-order: a b c d / * + c d a + (b * (c / d)) Why do some calculators support postfix notation?
