What order do we visit nodes in a tree? • Most common tree traversal orders: –Pre-order. –In-order. –Post-order.

To design and implement a binary search tree. To represent binary trees using linked data structures. To insert an element into a binary search tree.

By “traversal” we mean visiting all the nodes in a graph. Traversal strategies can be specified by the ordering of the three objects to visit: the current node, ...

Every node has 0 or 2 children. Page 7. Tree Traversals. A traversal is an order for visiting all the nodes of a tree. • Pre-order: root, left subtree, right ...

Hierarchical data structure with a single reference to root node. 2. Each node has at most two child nodes (a left and a right child).

Insert all keys into a BST. 2. Do an inorder traversal of BST. Remark. Correspondence is 1–1 if array has no duplicate keys.

the tree exactly once. ❖ There are 3 types of tree traversal techniques. ❖ Inorder Traversal. ❖ Preorder Traversal. ❖ Postorder Traversal ...

The successor is the node whose key would appear in the next sorted order. Think about traversal in-order. Who would be the successor of x? The parent of x!

Tree Traversal is Recursive. If the binary tree is empty then do nothing. Else. N: Visit the root, process data. L: Traverse the left subtree. R: Traverse the ...

When applying the in-order traversal to a tree, we apply it to the left-subtree first, since it contains strictly less than n(≥ 0) nodes, by the inductive ...
