Textbook Question
Chapter 8, Problem 8.31ASME
(Text Analysis) The availability of computers with string-manipulation capabilities has resulted in some rather interesting approaches to analyzing the writings of great authors. Much attention has been focused on whether William Shakespeare ever lived. Some scholars find substantial evidence that Christopher Marlowe actually penned the masterpieces attributed to Shakespeare. Researchers have used computers to find similarities in the writings of these two authors. This exercise examines three methods for analyzing texts with a computer.
- Write a
program that reads several lines of text and prints a table indicating the number of occurrences of each letter of the alphabet in the text. For example, the phrase - To be, or not to be: that is the question: contains one “a,” two “b’s,” no “c’s,” and so on.
- Write a program that reads several lines of text and prints a table indicating the number of one-letter words, two-letter words, three-letter words, and so on, appearing in the text. For example, the phrase
- Write a program that reads several lines of text and prints a table indicating the number of occurrences of each different word in the text. The program should include the words in the table in the same order in which they appear in the text. For example, the lines
Whether ‘tis nobler in the mind to suffer contains
Whether ‘tis nobler in the mind to suffer contain the words “to” three times, “be” two times, “or” once, and so on.

CODE IN PYTHON AND SHOW COMMENTS TO EXPLAIN CODE
A confused Dutchman trying to speak English could say “I am in the war”, even though there is no hostile activity going on. The confusion1 here is that the English sentence “I am confused” is translated in Dutch as “Ik ben in de war”, which is phonetically (“sounding”) quite close to the first sentence. Such confusion leads to much enjoyment, but can complicate matters a bit.
Given a sentence in Dutch and a dictionary containing both correct translations as well as phonetic (incorrect) translations of individual words, find the translation of the sentence and indicate whether it is correct, or in case there is more than one find the total number of correct and incorrect translations. A sentence is correctly translated when each word of the sentence is correctly translated.
Input
The input consists of:
One line with an integer n (1≤n≤20), the…
Exercise 1: (Design of algorithm to find greatest common divisor)
In mathematics, the greatest common divisor (gcd) of two or more integers
is the largest positive integer that divides each of the integers.
For example, the gcd of 8 and 12 is 4. Why?
Divisors of 8 are 1, 2, 4, 8.
Divisors of 12 are 1, 2, 4, 6, 12
Thus, the common divisors of 8 and 12 are 1, 2, 4.
Out of these common divisors, the greatest one is 4. Therefore, the greatest
common divisor (gcd) of 8 and 12 is 4.
Write a programming code for a function FindGCD(m,n) that find the greatest
common divisor. You can use any language of Java/C++/Python/Octave.
Find GCD Algorithm:
Step 1 Make an array to store common divisors of two integers m, n.
Step 2 Check all the integers from 1 to minimun(m,n) whether they divide
both m, n. If yes, add it to the array.
Step 3 Return the maximum number in the array.

CPU Usage
We have the hourly average CPU usage for a worker's computer over the course of a week. Each row of data represents a day of the week starting with Monday. Each column of data is an hour in the day starting with 0 being midnight.
Create a chart that shows the CPU usage over the week. You should be able to answer the following questions using the chart:
When does the worker typically take lunch?
Did the worker do work on the weekend?
On which weekday did the worker start working on their computer at the latest hour?

Otherwise, split the input into two halves, divided as evenly as possibly (if N is odd, one of the two halves will have one more element than the other). Recursively find the maximum and minimum of each half, and then in two additional comparisons produce the maximum and minimum for the entire problem.

- (Airline Reservations System) A small airline has just purchased a computer for its new automated reservations system. The president has asked you to program the new system. You’ll write a program to assign seats on each flight of the airline’s only plane (capacity: 10 seats). Your program should display the following menu of alternatives: Please type 1 for "first class" Please type 2 for "economy" If the person types 1, then your program should assign a seat in the first class section (seats 1– 5). If the person types 2, then your program should assign a seat in the economy section (seats 6– 10). Your program should then print a boarding pass indicating the person's seat number and whether it’s in the first class or economy section of the plane. Initialize all the elements of the array to 0 to indicate that all seats are empty. As each seat is assigned, set the corresponding element of the array to 1 to indicate that the seat is no longer available.

You’ll use random number generation to develop a simulation of this memorable event. Our contenders begin the race at square 1 of 70 squares. Each square represents a possible position along the race course. The finish line is at square 70. The first contender to reach or pass square 70 is rewarded with a pail of fresh carrots and lettuce. The course weaves its way up the side of a slippery mountain, so occasionally the contenders lose ground. Use variables to keep track of the positions of the animals (i.e., position numbers are 1–70). Start each animal at position 1 (i.e., the “starting gate”). If an animal slips left before square 1, move the animal back to square 1. Generate the percentages in Fig. 10.24 by producing a random integer i in the range 1 ≤i ≤10. For the tortoise, perform a “fast plod” when 1 ≤i…arrow_forward(Computer-Assisted Instruction: Reducing Student Fatigue) One problem in CAI environments is student fatigue.

The robot can move randomly in any of the directions: up, down, left, right. The robot can only move one step at a time. For each move, print the direction of the move in and the current position of the robot. Use formatted output to print the direction (Down, Up, Left or Right) in the left. The direction takes 10 characters in total and fill in the field with empty spaces. The statement to print results in such format is given below: cout << setw(10) << left << ‘Down’ << ... ; cout << setw(10) << left << ‘Up’ << ...; If the robot moves back to the original place (0,0), print “Back to the origin!” to the console and stop the program. If it reaches the boundary of the grid, print “Hit the boundary!” to the console and stop the program. A successful run of your code may look like: Due to randomness, your results may have a different trajectory…arrow_forward
