Suppose we have another file with only ASCII symbols. But we decided to encode the file in the following way using Huffman Encoding: instead of treating each character as a unique symbol, we use 2 characters together as a unique symbol. For example, if the file content is ABABCCDD. Then there are 4 total symbols (2 ABs, 1 CC, and 1 DD). Please explain how this approach to construct symbols may impact the compression process. More specifically, explain how this would impact the size of Huffman Tree, the header size, and the compression rate. Use a concrete example to help you explain.

. 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...
(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....
We have the symbols A, B, C, D, E, F, G, H with frequencies 1, 1, 2, 4, 8, 16, 32, 64. Show the Huffman tree and Huffman code for the symbols. How much compression does a 1000 digit file use when using this Huffman code based on an 8-bit ASCII code (ie, ISO 8859-1)?
C language huffman This exercise will familiarize you with linked lists, which you will need for a subsequent programming Getting Started assignment Overview Requirements Getting Started Submit Start by getting the files. Type 264get hw13 and then cd hw13 from bash. Pre-tester You will get the following files: Q&A Updates 1. huffman.h: An empty header file, you have to define your own functions in this homework. 2. huffman.c: An empty c file, you have to define your own functions in...
PLEASE CODE IN PYTHON Run-length encoding is a simple compression scheme best used when a data-set consists primarily of numerous, long runs of repeated characters. For example, AAAAAAAAAA is a run of 10 A’s. We could encode this run using a notation like *A10, where the * is a special flag character that indicates a run, A is the symbol in the run, and 10 is the length of the run. As another example, the string KKKKKKKKKKKKKBCCDDDDDDDDDDDDDDDKKKKKMNUUUGGGGG would be encoded...
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...
C++. Need some help getting started. We will also have the following two functions: 1. A mutate function that randomly modifies a chromosome. 2. A crossover function that takes two chromosomes and splits each one at the same spot, then combines them together. Our genetic algorithm works by iterating over generations of chromosomes via the following process: 1. Generate random population. 2. Until we get an answer that is good enough, do the next steps in a loop: (a) Do...
