. Huffman Encoding (a.) (6 points) Suppose a certain file contains only the following letters with the corresponding frequencies 1 AİB 73 9 30 44 130 28 16 In a fixed-length encoding scheme, cach character is given a binary representation with the same number of bits. What is the minimum number of bits required to represent each letter of this file under fixed-length encoding scheme? Describe how to encode all seven letters in this file using the number of bits...

You will construct a Huffman tree based on the given frequencies of 26 English alphabets in upper case plus the space character. An internal tree node class in HuffmanTree with necessary information is required. • You will not randomly switch left and right children when merger two trees. Instead, you will build a right-heavy tree according to the following strategies to select the right child. (1) The tree that is taller will be the right child, i.e., the height is...

(b.) Huffman code is a way to encode information using variable-length binary strings to represent symbols depending on the frequency of each individual letter. Specifically, letters that appear more frequently can be encoded into strings of shorter lengths, while rarer letters can be turned into longer binary strings. On average, Huffman code is a more efficient way to encode a message as the number of bits in the output string will be shorter than if a fixed-length code was used....

(a) Create a Huffman code for the following string (whitespace inserted for clarity): AAA BB CCCCC CCCCC DD EEE (b) How many bits does your code use to encode the above string? (c) Huffman codes are always optimal prefix codes, and there are many different ways one can build a Huffman code from the same set of character frequencies (e.g. by swapping the left and right subtrees at any iteration). Give an example of an optimal prefix code for this...

Problem (A1) (20 points): Huffman Coding Consider a message having the 5 symbols (A,B,C,D,E) with probabilities (0.1,0.1,0.2 ,0.2, 0.4), respectively. For such data, two different sets of Huffman codes can result from a different tie breaking during the construction of the Huffman trees. • Construct the two Huffman trees. (8 points) Construct the Huffman codes for the given symbols for each tree. (4 points) Show that both trees will produce the same average code length. (4 points) For data transmission...

3. (8 points) Using the implementation of binary search tree operations we discussed in class, draw the trees that result from the following operations: (a) Inserting 142, 400, 205, 127, 100, 320, 160, 141, and 110 into an initially-empty tree (in that order). (b) Deleting 142 from the tree you drew for part (a). 4. (8 points) Draw the unique binary tree that has a preorder traversal of 4, 1, 6, 3, 7, 5, 9, 2, 8 and an inorder...

1. (50 POINTS) A divide-by-N counter is a special type of a counter with one output and no inputs. The output Y is high for one clock cycle out of every N, i.e. the output divides the clock frequency by N. As an example, the waveform for a divide-by-3 counter and the corresponding FSM for this counter are shown below S1 Y. O S2 Y. O SO Now, consider a divide-by-4 counter to answer the following I.A.)

Write a Java program that does the following: 1. Creates a string array called firstNames that holds these values "John", "Frank", "Nick", "Amanda", "Brittany", "Amy", "Deborah", and "Stirling". 2. Creates another string array called lastNames that holds these values "Thompson", "Smith", "Jones", "Keribarian", "Lu", "Banafsheh", "Spielberg", "Jordan", "Castle" and "Simpson". 3. Now add a method that creates an array list called randomNames which picks a random first name from the array in step 1 and a random last name in...
