Trees and Graphs

Overview: The problems for this assignment should be written up in a Mircosoft Word document. A scanned hand written file for the diagrams is also fine. Be sure to include your name and course number within all of the files that you submit.

1.Trees

Read the assigned chapter and notes for Week 5 located in the Course Documents area.

(a)

Draw a binary tree that produces the inorder traversal for the nodes in the following

order: 721, 174, 788, 828, 61, 292, 986, 3, 394, 154, 86, 229.

Hint: Y

our tree must a binary tree and not a binary search tree. The tree must produce the inorder traversal for the nodes listed in the order provided above. There are several ways that you can draw the tree for this. I recommend first drawing the nodes and links and then filling in the nodes with the correct values that produces the inorder traversal.

(b)  Briefly explain some of the differences between a multiway tree and a binary search

tree.
2. Graphs

Read the assigned chapter and notes for Week 6 located in the Course Documents area.

(a)  Draw the adjacency list for the following graph:

(b) Briefly state the differences between a sparse and a dense graph, and the mathematical property for each. Also, explain whether a sparse or dense graph is best implemented using and adjacency matrix and why.

Since the signi?cance of the states represented by the nodes of these transition graphs is arbitrary, we will allow ourselves to use any ?nite set (such as {A,B,C,D,E, F,G,H} or ev

Computer has a single LIFO stack containing ?xed precision unsigned integers (so each integer is subject to over?ow problems) but which has unbounded depth (so the stack itself nev

Strictly 2-local automata are based on lookup tables that are sets of 2-factors, the pairs of adjacent symbols which are permitted to occur in a word. To generalize, we extend the

You are required to design a system that controls the speed of a fan's rotation. The speed at which the fan rotates is determined by the ambient temperature, i.e. as the temperatur
