...A very big text file contains only the first 8 characters of the alphabet a, b, c,h. The frequency of occurrence of each character is given below. Draw diagramssimilar to those in Figs 10.13 to 10.19 in the text book (Weiss, pages 456-458) toshow how you build a Huffman-coding tree. What would be the length of theHuffman-coded file? What is the compression ratio compared to using 3 bits percharacter? What is the code for the word bagh?a: 5000 b: 2000 c 15000 d: 30000 e: 21000 f: 4000 g: 11000 h:12000

Now, we have our Huffman coding tree. To find the Huffman code for each character, we traverse the…

. The classical Tower of Hanoi (ToH) puzzle is well-known. It consists of three pegs and disks of sizes 1,2, . . . , n arranged on one of the pegs as a “tower”, in decreasing order of size, from bottom to top. The goal of the puzzle is to transfer all disks to another peg, placed in the same order. At each step, a single disk is moved from (the top of) one peg to (the top of) another, subject to the “divine” rule: to never have a larger disk above a smaller one.
Computer Science Write a script file to make a table with x and y columns with 100 rows and plot the curve y as a function of x, where y(x)=sin(ax)-cos(bx). The values a, b, and range of x must be entered through input. Demonstrate that your program script file works for the case a is 8 and b is 2 and in addition plot x from 0 to 2π. Label the axis x and y of the figure.

Create a Huffman compression code for the phrase “Expecto Patronum” (ignoring character case). You answer should include your Huffman code tree (including clear illustration of it’s development) plus the resultant encoded phrase.
barcode scanner for Universal Product Codes(UPCs) verifies the 12-digit code scanned by comparing thecode’s last digit (called a check digit ) to its owncomputation of the check digit from the first 11 digits asfollows:I. [step 1]Calculate the sum of the digits in theodd-numbered positions (the first, third, …,eleventh digits) and multiply this sum by 3.II. [step 2]Calculate the sum of the digits in theeven-numbered positions (the second, fourth, …,tenth digits) and add this to the previousresult(result of step1).III. [step 3]If the last digit of the result from step2 is 0, then 0 is the check digit. Otherwise,subtract the last digit from 10 to calculate thecheck digit.IV. [step 4]If the check digit matches the final digitof the 12-digit UPC, the UPC is assumed correct.1. Write main function that prompts the user to enterthe 12 digits of a barcode. The program shouldstore the digits in an integer array.2. Write a “check” function to calculate the checkdigit, and compare it to the final…
