For this assignment, you will write a program to work with Huffman encoding. Huffman code is an optimal prefix code, which means no code is the prefix of another code. Most of the code is included. You will need to extend the code to complete three additional methods. In particular, code to actually build the Huffman tree is provided. It uses a data file containing the frequency of occurrence of characters. You will write the following three methods in the...
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...

(4) Select the best choice as Huffman code for the following symbols and their probabilities: A-0.10 C-0.17 E-0.21 B-0.21 D-0.06 F-0.25 (a) A: O, B: 10, C: 110, D: 1110, E: 11110, F: 11111 (b) A: 0,B: 10, C: 11111, D: 1110, E: 11110, F: 110 (c) A: 11110, B: 10, C: 1110, D: 11111, E: 110, F: 0 (d) A: 11111, B: 11110, C: 1110, D: 110, E: 10, F: 0 (e) A: 0,B: 01, C: 0001, D:...
Matrices are used to encode and decode encrypted 6: Matrices and Cryptography messages. Using the following code, Task KİLİMİN | SPACE |-Z --T-T-u一ㄒㄧˇ-ㄒㄧ-w-ㄒㄧㄨㄧㄧㄧㄚ s116 17 18 19 20 21 22 23 24 25 26 The sentence MATRICES ARE FUN becomes: FİUİN AİRİE 0161211 14 9L3151 1910|111813 a. To encode the message, multiply by an invertible matrix A. Write the coded message in a 3x6 matrix, adding 0's for blanks. Calculate the product using a graphing calculator. [7-3-31「13 18 5 1...
(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....
5. If we apply binary dilation to the same large object twice using the same small structuring element, the effect, if any, of the second dilation on the object is that the object: (a) is unchanged (b) is completely removed (c) becomes larger (d) becomes smaller (e) does not change 6. Which of the following is/are true? (a) Dijkstra's algorithm can be used to find shortest paths in a network (b) Dijkstra's algorithm is a method to find straight lines...

Write a C++ program which makes a binary tree that generates the Huffman code for any 7 characters and their given frequencies. As test input use a 3, b 4, c 1, d 3, e 12, f 4, g 2. Your program must insert nodes, and output the code for each character. Note: your program should be able to take any 7 characters and their frequencies as input. Three extra points if your program can accept 26 letters and 10...
I need to update this code: #include <iostream> #include <string> #include <cctype> using namespace std; int main() { string s; cout<< "Enter a string" <<endl; getline (cin,s); cout<< s <<endl; int vowels=0,consonants=0,digits=0,specialChar=0; for (int i=0; i<s.length(); i++) { char ch=s[i]; if (isalpha(s[i])!= 0){ s[i]= toupper(s[i]); if (ch == 'a'|| ch == 'e'|| ch == 'i'|| ch == 'o' || ch == 'u') vowels++; else consonants++; } else if (isdigit(s[i])!= 0) digits++; else specialChar++; } cout<<"Vowels="<<vowels<<endl; cout<<"Consonants="<<consonants<<endl; cout<<"Digits="<<digits<<endl; cout<<"Special Characters="<<specialChar<<endl;...
