Suppose you have a class called Child with an instance data value called weight and height. Then it has a method called doubleWeight that stores a local double variable called superWeight that multiplies the two instance variables and stores the value in superWeight, and this method returns a double value. Write a getter method and a setter method for weight, and then make them for height.

Answer:

Explanation:

The following code is written in Java. I recreated the entire Child class as described with the instance variables and the doubleWeight method. Then created the getter and setter methods for both the weight and height variables.

class Child {

   double weight, height;

   public double doubleWeight() {

       double superWeight = weight * height;

       return superWeight;

   }

   public double getWeight() {

       return weight;

   }

   public void setWeight(double weight) {

       this.weight = weight;

   }

   public double getHeight() {

       return height;

   }

   public void setHeight(double height) {

       this.height = height;

   }

}

mips Write a program that asks the user for an integer between 0 and 100 that represents a number of cents. Convert that number of cents to the equivalent number of quarters, dimes, nickels, and pennies. Then output the maximum number of quarters that will fit the amount, then the maximum number of dimes that will fit into what then remains, and so on.

You are on a team of developers writing a new teacher tool. The students names are stored in a 2D array called “seatingChart”. As part of the tool, a teacher can enter a list of names and the tool well return the number of students in the class found with names that matching provided list. For this problem you will be completing the ClassRoom class in the problem below. Your job is to complete the numberOfStudents found method. This method accepts an array of Strings that contain names and returns the quantity of students with those names. For example:
Assume that a ClassRoom object named “computerScience” has been constructed and the seating chart contains the following names:


“Clarence”, “Florence”, “Ora”


“Bessie”, “Mabel”, “Milton”


“Ora”, “Cornelius”, “Adam”


When the following code executes:


String[] names = {"Clarence", "Ora", "Mr. Underwood"};

int namesFound = computerScience.numberOfStudents(names);

The contents of namesFound is 3 because Clarence is found once, Ora is found twice, and Mr. Underwood is not found at all. The total found would be 3.


Complete the numberOfStudents method

public class ClassRoom

{


private String[][] seatingChart;


//initializes the ClassRoom field seatingChart

public ClassRoom(String[][] s){

seatingChart = s;

}



//Precondition: the array of names will contain at least 1 name that may or may not be in the list

// the seating chart will be populated

//Postcondition: the method returns the number of names found in the seating chart



//TODO: Write the numberOfStudents method


public int numberOfStudents(String[] names){





}

Kenneth bought a new phone and added two of his friends' numbers to his phonebook. However, he forgot to transfer the phonebook from his previous phone beforehand. Help Kenneth keep the most up-to-date phone numbers for all his friends on his new device. That is, if there is a number saved on both old and new devices for the same friend, you should keep the number saved on the new phone; or if there is only one phone number for a friend, you should keep it, regardless of which device contains it.

In Scheme, source code is data. Every non-atomic expression is written as a Scheme list, so we can write procedures that manipulate other programs just as we write procedures that manipulate lists.
Rewriting programs can be useful: we can write an interpreter that only handles a small core of the language, and then write a procedure that converts other special forms into the core language before a program is passed to the interpreter.
For example, the let special form is equivalent to a call expression that begins with a lambda expression. Both create a new frame extending the current environment and evaluate a body within that new environment. Feel free to revisit Problem 15 as a refresher on how the let form works.
(let ((a 1) (b 2)) (+ a b))
;; Is equivalent to:
((lambda (a b) (+ a b)) 1 2)
These expressions can be represented by the following diagrams:
Let Lambda
let lambda
Use this rule to implement a procedure called let-to-lambda that rewrites all let special forms into lambda expressions. If we quote a let expression and pass it into this procedure, an equivalent lambda expression should be returned: pass it into this procedure:
scm> (let-to-lambda '(let ((a 1) (b 2)) (+ a b)))
((lambda (a b) (+ a b)) 1 2)
scm> (let-to-lambda '(let ((a 1)) (let ((b a)) b)))
((lambda (a) ((lambda (b) b) a)) 1)
In order to handle all programs, let-to-lambda must be aware of Scheme syntax. Since Scheme expressions are recursively nested, let-to-lambda must also be recursive. In fact, the structure of let-to-lambda is somewhat similar to that of scheme_eval--but in Scheme! As a reminder, atoms include numbers, booleans, nil, and symbols. You do not need to consider code that contains quasiquotation for this problem.
(define (let-to-lambda expr)
(cond ((atom? expr) )
((quoted? expr) )
((lambda? expr) )
((define? expr) )
((let? expr) )
(else )))
CODE:
; Returns a function that checks if an expression is the special form FORM
(define (check-special form)
(lambda (expr) (equal? form (car expr))))
(define lambda? (check-special 'lambda))
(define define? (check-special 'define))
(define quoted? (check-special 'quote))
(define let? (check-special 'let))
;; Converts all let special forms in EXPR into equivalent forms using lambda
(define (let-to-lambda expr)
(cond ((atom? expr)

Implement the above in c++, you will write a test program named create_and_test_hash.cc . Your programs should run from the terminal like so:
./create_and_test_hash should be "quadratic" for quadratic probing, "linear" for linear probing, and "double" for double hashing. For example, you can write on the terminal:
./create_and_test_hash words.txt query_words.txt quadratic You can use the provided makefile in order to compile and test your code. Resources have been posted on how to use makefiles. For double hashing, the format will be slightly different, namely as follows:
./create_and_test_hash words.txt query_words.txt double The R value should be used in your implementation of the double hashing technique discussed in class and described in the textbook: hash2 (x) = R – (x mod R). Q1. Part 1 (15 points) Modify the code provided, for quadratic and linear probing and test create_and_test_hash. Do NOT write any functionality inside the main() function within create_and_test_hash.cc. Write all functionality inside the testWrapperFunction() within that file. We will be using our own main, directly calling testWrapperFunction().This wrapper function is passed all the command line arguments as you would normally have in a main. You will print the values mentioned in part A above, followed by queried words, whether they are found, and how many probes it took to determine so. Exact deliverables and output format are described at the end of the file. Q1. Part 2 (20 points) Write code to implement double_hashing.h, and test using create_and_test_hash. This will be a variation on quadratic probing. The difference will lie in the function FindPos(), that has to now provide probes using a different strategy. As the second hash function, use the one discussed in class and found in the textbook hash2 (x) = R – (x mod R). We will test your code with our own R values. Further, please specify which R values you used for testing your program inside your README. Remember to NOT have any functionality inside the main() of create_and_test_hash.cc
You will print the current R value, the values mentioned in part A above, followed by queried words, whether they are found, and how many probes it took to determine so. Exact deliverables and output format are described at the end of the file. Q1. Part 3 (35 points) Now you are ready to implement a spell checker by using a linear or quadratic or double hashing algorithm. Given a document, your program should output all of the correctly spelled words, labeled as such, and all of the misspelled words. For each misspelled word you should provide a list of candidate corrections from the dictionary, that can be formed by applying one of the following rules to the misspelled word: a) Adding one character in any possible position b) Removing one character from the word c) Swapping adjacent characters in the word Your program should run as follows: ./spell_check
You will be provided with a small document named document1_short.txt, document_1.txt, and a dictionary file with approximately 100k words named wordsEN.txt. As an example, your spell checker should correct the following mistakes. comlete -> complete (case a) deciasion -> decision (case b) lwa -> law (case c)
Correct any word that does not exist in the dictionary file provided, (even if it is correct in the English language). Some hints: 1. Note that the dictionary we provide is a subset of the actual English dictionary, as long as your spell check is logical you will get the grade. For instance, the letter "i" is not in the dictionary and the correction could be "in", "if" or even "hi". This is an acceptable output. 2. Also, if "Editor’s" is corrected to "editors" that is ok. (case B, remove character) 3. We suggest all punctuation at the beginning and end be removed and for all words convert the letters to lower case (for e.g. Hello! is replaced with hello, before the spell checking itself).
Do NOT write any functionality inside the main() function within spell_check.cc. Write all functionality inside the testSpellingWrapper() within that file. We will be using our own main, directly calling testSpellingWrapper(). This wrapper function is passed all the command line arguments as you would normally have in a main

One of your start-ups uses error-correcting codes, which can recover the original message as long as at least 1000 packets are received (not erased). Each packet gets erased independently with probability 0.8. How many packets should you send such that you can recover the message with probability at least 99%

Defining a Figure of Merit
Consider a string-matching figure of merit. That is, it tells you how close to a given string another string is. Each matching letter in the same spot is worth one point. Only letters need be considered.
For instance, if the secret string reads 'BLACKBEARD', then 'BEACKBEARD' is worth 9 points, 'WHITEBEARD' is worth 5 points, 'BEARDBLACK' is worth 4 points, and 'CALICOJACK' is worth 1 point.
Compose a function pirate which accepts a string of characters guess and returns the number of characters which match the secret string 'BLACKBEARD'. It should be case-insensitive; that is, you should convert input to upper-case letters. It should return zero for strings which are not ten characters in length.
Your submission should include a function pirate( guess ) which returns a float or int representing the number of matching characters. (You should provide the secret string 'BLACKBEARD' inside the function, not outside of it.)
strings should not have same lengths
