10) A binary tree with N nodes is at least how deep? How deep is it at most? 12) A Binary Search Tree is a binary tree with what additional property? 13) Beginning with an empty binary search tree, insert the following values in the order given. Draw the tree at each step of the process. 1 10 5 20 22 7 14) Now delete the value 10 from the tree in question 13. Show each of two possible configurations...

Write a O(n) method valuesInLevelOrder() that returns a list of the nodes of a binary tree in level-order. That is, the method should return the root, then the nodes at depth 1, followed by the nodes at depth 2, and so on. Your algorithm should begin by putting the tree root on an initially empty queue. Then dequeue a node, add it to the output, and enqueue its left and right children (if they exist). Repeat until the queue is...

a.) Let T be a binary tree with n nodes. Define the lowest common ancestor (LCA) between two nodes v and w as the lowest node in T that has both v and w as descendants. Given two nodes v and w, write an efficient algorithm, LCA(v, w), for finding the LCA of v and w. Note: A node is a descendant of itself and v.depth gives a depth of a node v. b.) What is the running time of your...

Show that any graph with n vertices and δ(G) ≥ n/2 + 1 has a triangle.
