Describe and compare imperative (C), functional (SML) and logic (Prolog) programming paradigms.
Answer:
Answered below
Explanation:
Imperative programming paradigm is a paradigm in which the programmer tells the machine how to change its state. It is divided into procedural programming, where programs are grouped as procedures, and object-oriented, where programs are grouped together with the properties they operate on.
Imperative paradigm is efficient, familiar and popular compared to others.
Functional programming paradigm implements all instructions as functions, in a mathematical sense. They take on an argument and return a single solution. The advantage of this, compared to other paradigms, is its abstraction and independence.
Logical programming, like functional programming, incorporates a declarative approach to problem solving. All known facts are first established before queries are made. Advantage of this paradigm is that programming steps are kept to a minimum.

Consider a bit stuffing framing method where the start of a frame is indicated by 6 consecutive ones, followed by 2 zeroes. What should be the bit stuffing rules at the transmitter? What should be the bit destuffing rules at the receiver? Fill in the blank to show what is the stream after bit stuffingWrite the rule for stuffing:Write the rule for destuffing:Assume the user data stream before bit stuffing is 011111100011111101. What is the stream after bit stuffing?
Answer:
Explanation:
Bit stuffing Framing Method
In the given situation, the beginning casing is shown by 6 sequential ones followed by 2 zeroes.
The beginning casings are generally known as the flags.which are utilized for demonstrating the beginning and end of the edges. Essentially utilized for the synchronization between the sender and the reciever.
Along these lines here the beginning and end banners are 11111100(this is on the grounds that the end banner is same as the beginning banner).
To enable us understand how this question plays out, let us understand the rule for Stuffing and De-stuffing .
The standard for stuffing is :
At whatever point there are 5 successive ones supplement one zero in the casing which is an information. The embedded zero piece is known as the stuffed bit.The principle reason behind stuffing somewhat after 5 back to back ones is to evade the distortion of information (data) as flag. If the reciever misconstrues the information as end banner then he would quit recieving the information where the entire information sent by the sender will be left and lost causing an error-prone information.
The rule for destuffing :
The standard/rule for destuffing is only inverse as stuffing. After recieving the bitstuffed information (data), at the reciever's end zero after each 5 continuous ones will be evacuated and the rest of the information will be considered as the genuine information.
In the given situation, the beginning casing is demonstrated by 6 back to back ones followed by 2 zeroes.
the beginning casings are normally known as the flags.which are utilized for showing the beginning and end of the edges. Essentially utilized for the synchronization between the sender and the receiver.
In this way here the beginning and end banners are 11111100(this is on the grounds that the end banner is same as the beginning banner).
data before bit stuffing is: 011111100011111101the stream after stuffing would be: 01111101000111101101where the bolded/underlined digits represents the stuffed bits

Append newValue to the end of vector tempReadings. Ex: If newValue = 67, then tempReadings = {53, 57, 60} becomes {53, 57, 60, 67}.
#include
#include
using namespace std;
int main() {
vector tempReadings(3);
int newValue = 0;
unsigned int i = 0;
tempReadings.at(0) = 53;
tempReadings.at(1) = 57;
tempReadings.at(2) = 60;
newValue = 67;

int main() {
vector ticketList(3);
unsigned int i = 0;
ticketList.at(0) = 5;
ticketList.at(1) = 100;
ticketList.at(2) = 12;
/* Your solution goes here */
for (i = 0; i < ticketList.size(); ++i) {
cout << ticketList.at(i) << " ";
}
cout << endl;
return 0;
}
3. Assign the size of vector sensorReadings to currentSize.
#include
#include
using namespace std;
int main() {
vector sensorReadings(4);
int currentSize = 0;
sensorReadings.resize(10);
/* Your solution goes here */
cout << "Number of elements: " << currentSize << endl;
return 0;
}
4. Write a statement to print "Last mpg reading: " followed by the value of mpgTracker's last element. End with newline. Ex: If mpgTracker = {17, 19, 20}, print:
Last mpg reading: 20
#include
#include
using namespace std;
int main() {
vector mpgTracker(3);
mpgTracker.at(0) = 17;
mpgTracker.at(1) = 19;
mpgTracker.at(2) = 20;
/* Your solution goes here */
return 0;}
Answer:
Following are the code to this question:
In question 1:
tempReadings.push_back(newValue); //using array that store value in at 3 position
In question 2:
ticketList.pop_back(); //defining ticketList that uses the pop_back method to remove last insert value
In question 3:
currentSize = sensorReadings.size(); /defining currentSize variable holds the sensorReadings size value
In question 4:
cout<<"Last mpg reading: "<<mpgTracker.at(mpgTracker.size()-1)<<endl;
//using mpgTracker array with at method that prints last element value
Explanation:
please find the attachment of the questions output:
In the first question, it uses the push_back method, which assigns the value in the third position, that is "53, 57, 60, and 67 "In the second question, It uses the pop_back method, which removes the last element, that is "5 and 100"In the third question, It uses the "currentSize" variable to holds the "sensorReadings" size value, which is "10".In the fourth question, It uses the mpgTracker array with the "at" method, which prints the last element value, which is "20".Using data from interviews with ESCO executives conducted in late 2012, this study examines the market size, growth forecasts, and industry trends in the United States for the ESCO sector.
Thus, It uses the "currentSize" variable to holds the "sensorReadings" size value, which is "10". In the fourth question, It uses the mpgTracker array with the "at" method, which prints the last element value, which is "20".

Declare a class named PatientData that contains two attributes named height_inches and weight_pounds. Sample output for the given program with inputs: 63 115 Patient data (before): 0 in, 0 lbs Patient data (after): 63 in, 115 lbs 1 Your solution goes here ' 2 1 test passed 4 patient PatientData () 5 print('Patient data (before):, end-' ') 6 print(patient.height_inches, 'in,, end=' ') 7 print(patient.weight_pounds, lbs') All tests passed 9 10 patient.height_inches = int(input()) 11 patient.weight_pounds = int(input()) 12 13 print('Patient data (after):', end-' ') 14 print (patient. height_inches, 'in,', end- ') 15 print(patient.weight_pounds, 'lbs') Run
Answer:
class PatientData(): #declaration of PatientData class
height_inches=0 #attribute of class is declared and initialized to 0
weight_pounds=0 #attribute of class is declared and initialized to 0
Explanation:
Here is the complete program:
#below is the class PatientData() that has two attributes height_inches and weight_pounds and both are initialized to 0
class PatientData():
height_inches=0
weight_pounds=0
patient = PatientData() #patient object is created of class PatientData
#below are the print statements that will be displayed on output screen to show that patient data before
print('Patient data (before):', end=' ')
print(patient.height_inches, 'in,', end=' ')
print(patient.weight_pounds, 'lbs')
#below print statement for taking the values height_inches and weight_pounds as input from user
patient.height_inches = int(input())
patient.weight_pounds = int(input())
#below are the print statements that will be displayed on output screen to show that patient data after with the values of height_inches and weight_pounds input by the user
print('Patient data (after):', end=' ')
print(patient.height_inches, 'in,', end=' ')
print(patient.weight_pounds, 'lbs')
Another way to write the solution is:
def __init__(self):
self.height_inches = 0
self.weight_pounds = 0
self keyword is the keyword which is used to easily access all the attributes i.e. height_inches and weight_pounds defined within a PatientData class.
__init__ is a constructor which is called when an instance is created from the PatientData, and access is required to initialize the attributes height_inches and weight_pounds of PatientData class.
The program along with its output is attached.
In this exercise we have to use the knowledge of computational language in python to describe a code, like this:
The code can be found in the attached image.
To make it easier the code can be found below as:
class PatientData():
height_inches=0
weight_pounds=0
patient = PatientData()
print('Patient data (before):', end=' ')
print(patient.height_inches, 'in,', end=' ')
print(patient.weight_pounds, 'lbs')
patient.height_inches = int(input())
patient.weight_pounds = int(input())
print('Patient data (after):', end=' ')
print(patient.height_inches, 'in,', end=' ')
print(patient.weight_pounds, 'lbs')

Implement a recursive method named power that takes 2 integer parameters named base and expo. The method will return the base raised to the power of expo.
Answer:
def power(base, expo):
if expo == 0:
return 1
else:
return base * power(base, expo-1)
Explanation:
*The code is in Python.
Create a method called power that takes base and expo as parameters
Check if the expo is equal to 0. If it is return 1 (This is our base case for the method, where it stops. This way our method will call itself "expo" times). If expo is not 0, return base * power(base, expo-1). (Call the method itself, decrease the expo by 1 in each call and multiply the base)

The policy that allows a transaction to commit even if it has modified some blocks that have not yet been written back to disk is called the __________ policy.
Answer:
No-force policy
Explanation:
The policy that allows a transaction to commit even if it has modified some blocks that have not yet been written back to disk is called the _NO-FORCE_ policy.
In data theory, the No-Force Policy is beneficial for the control of transaction. In this policy, when a transaction commits, changes that are made are not required to be written to disk in place. The changes recorded are preserved in order to make transaction durable. The recorded changes must be preserved at commit time.

If our HMap implementation is used (load factor of 75% and an initial capacity of 1,000), how many times is the enlarge method called if the number of unique entries put into the map is:_______
a. 100
b. 750
c. 2,000
d. 10,000
e. 100,000
Answer:
A) for 100 : < 1 times
b) for 750 : < 1 times
c) For 2000 = 1 time
D) for 10000 = 4 times
E) for 100000 = 7 times
Explanation:
Given data:
load factor = 75%
initial capacity = 1000
The number of times the enlarge method will be called for a unique number of entries would be 2 times the initial capacity ( 1000 ) because the load factor = 75% = 0.75
A) for 100 : < 1 times
b) for 750 : < 1 times
C) For 2000
= initial capacity * 2 = 2000 ( 1 time )
D) for 10000
= 1000 * 2 *2 *2*2 = 16000 ( 4 times )
to make it 10000 we have to add another 2000 which will make the number of times = 4 times
E)for 100000
= 1000*2*2*2*2*2*2*2= 128000 ( 7 times )
unique entry of 100000 is contained in 7 times

Note that the last element is not followed by a comma, space, or newline.
#include

int i = 0;
hourlyTemp[0] = 90;
hourlyTemp[1] = 92;
hourlyTemp[2] = 94;
hourlyTemp[3] = 95;
/* Your solution goes here */
cout << endl;
return 0;
}
Answer:
string sep = "";
for (i = 0; i < NUM_VALS; i++) {
cout << sep << hourlyTemp[i];
sep = ", ";
}
Explanation:
Insert the snippet at the commented location.
With the absence of a join() method as found in other languages, it is always a hassle to suppress that separator comma from appearing at the beginning or the end of your output. This solution is nice since it doesn't require any magic flags to keep track of wether the first element was printed.

The Adjacent Coins Problem Published on 2017-08-30 Consider N coins aligned in a row. Each coin is showing either heads or tails. The adjacency of these coins is the number of adjacent pairs of coins with the same side facing up. Write a program that given a non-empty zero-indexed array A consisting of N integers representing the coins, returns the maximum possible adjacency that can be obtained by reversing exactly one coin (that is, one of the coins must be reversed). Consecutive elements of array A represent consecutive coins in the row. Array A contains only 0s and/or 1s:
Answer:
Here is the JAVA code:
public class Main{
public static int solution(int[] A) { //method that takes non-empty array A consisting of 0s and 1s
int N = A.length; // number of 0s and 1s in array A
int r = 0; //result of adjacency
for (int i = 0; i < N - 1; i++; ) { // iterates through A
if (A[i] == A[i + 1]) //if i-th element of A is equal to (i+1)th element
r = r + 1; } //add 1 to the count of r
if (r == N-1) //for test cases like {1,1}
{return r-1; }
int max = 0; //to store maximum possible adjacency
for (int i = 0; i <N; i++) { //iterates through array
int c = 0;
if (i > 0) { //starts from 1 and covering the last
if (A[i-1] != A[i]) //checks if i-1 element of A is not equal to ith element of A
c = c + 1; //adds 1 to counter variable
else
c = c - 1; } //decrements c by 1
if (i < N - 1) {//starting with 0
if (A[i] != A[i + 1]) //checks if ith element of A is not equal to i+1th element of A
c = c + 1; //adds 1 to counter variable
else
c = c - 1; } //decrements c by 1
max = Math.max(max,c); } //finds the maximum of max and c
return r + max; } //returns result + maximum result
public static void main(String[] args) {
int[] A = {1, 1, 0, 1, 0, 0}; //sample array to test the method
System.out.println(solution(A));} } //calls the method passing array to it
Explanation:
The program works as follows:
A[] = {1, 1, 0, 1, 0, 0}
N = A.length
N = 6
The A has the following elements:
A[0] = 1
A[1] = 1
A[2] = 0
A[3] = 1
A[4] = 0
A[5] = 0
Program iterates through array A using for loop. Loop variable i is initialized to 0
if condition if (A[i] == A[i + 1]) checks
if (A[0] == A[0 + 1])
A[0] = 1
A[0 + 1] = A[1] = 1
They both are 1 so they are equal
r = r + 1;
Since the above if condition is true so 1 is added to the value of r Hence
r = 1
At each iteration of the loop the if condition checks whether the adjacent elements of A are equal. If true then r is incremented to 1 otherwise not.
So after all the iterations value of r = 2
if (r == N-1) evaluates to false because r=2 and N-1 = 5
So program moves to the statement:
for (int i = 0; i <N; i++)
This loop iterates through the array A
if (i > 0) condition checks if value of i is greater than 0. This evaluates to false and program control moves to statement:
if (i < N - 1) which makes if(0<5) This evaluates to true and program control moves to statement
if (A[i] != A[i + 1]) which means:
if (A[0] != A[0 + 1]) -> if (A[0] != A[1])
We know that
A[0] = 1
A[1] = 1
So this evaluates to false and else part is executed:
value of c is decremented to 1. So c=-1
max = Math.max(max,c) statement returns the max of max and c
max = 0
c = -1
So max = 0
value of i is incremented to 1 so i = 1
At next step:
if (i < N - 1) which makes if(1<5) This evaluates to true and program control moves to statement
if (A[i] != A[i + 1]) which means:
if (A[1] != A[1 + 1]) -> if (A[1] != A[2])
A[1] = 1
A[2] = 0
So the statement evaluates to true and following statement is executed
c = c + 1; The value of c is incremented to 1. So
c = -1 + 1
Hence
Hence c= 0, max = 0 and i = 2
next step:
if (i < N - 1) which makes if(2<5) This evaluates to true and program control moves to statement
if (A[i] != A[i + 1]) which means:
if (A[2] != A[2 + 1]) -> if (A[2] != A[3])
A[2] = 0
A[3] = 1
So the statement evaluates to true and following statement is executed
c = c + 1; The value of c is incremented to 1. So
c = 0 + 1
c = 1
Hence
The statement max = Math.max(max,c) returns the max of max and c
max = 0
c = 1
So max = 1
Hence c= 1, max = 1 and i = 3
next step:
if (i < N - 1) which makes if(3<5) This evaluates to true and program control moves to statement
if (A[i] != A[i + 1]) which means:
if (A[3] != A[3 + 1]) -> if (A[3] != A[4])
A[3] = 1
A[4] = 0
So the statement evaluates to true and following statement is executed
c = c + 1; The value of c is incremented to 1. So
c = 1 + 1
c = 2
Hence
The statement max = Math.max(max,c) returns the max of max and c
max = 1
c = 2
So max = 2
Hence c= 2, max = 2 i = 4
next step:
if (i < N - 1) which makes if(4<5) This evaluates to true and program control moves to statement
if (A[i] != A[i + 1]) which means:
if (A[4] != A[4+ 1]) -> if (A[4] != A[5])
A[4] = 0
A[5] = 0
So this evaluates to false and else part is executed:
value of c is decremented to 1. So c=1
max = Math.max(max,c) statement returns the max of max and c
max = 2
c = 1
So max = 2
value of i is incremented to 1 so i = 5
next step:
if (i < N - 1) which makes if(5<5) This evaluates to false
if (i > 0) evaluates to true so following statement executes:
if (A[i-1] != A[i])
if (A[5-1] != A[5])
if (A[4] != A[5])
A[4] = 0
A[5] = 0
This statement evaluates to false so else part executes and value of c is decremented to 1
Hence
max = 2
c = 0
So max = 2
value of i is incremented to 1 so i = 6
The loop breaks because i <N evaluates to false.
Program control moves to the statement:
return r + max;
r = 2
max = 2
r + max = 2+2 = 4
So the output of the above program is:
4
Define a function readList with one parameter, the (string) name of a file to be read from. The file consists of integers, one per line. The function should return a list of the integers in the file.
Answer:
Here is the Python function readList:
def readList(filename): #function definition of readList that takes a filename as a parameter and returns a list of integers in the file
list = [] # declares an empty list
with open(filename, 'r') as infile: # opens the file in read mode by an object infile
lines = infile.readlines() # returns a list with each line in file as a list item
for line in lines: #loops through the list of each line
i = line[:-1] # removes new line break which is the last character of the list of line
list.append(i) # add each list item i.e. integers in the list
return list #returns the list of integers
#in order to check the working of the above function use the following function call and print statement to print the result on output screen
print(readList("file.txt")) #calls readList function by passing a file name to it
Explanation:
The program is well explained in the comments mentioned with each line of the code.
The program declares an empty list.
Then it opens the input file in read mode using the object infile.
Next it uses readLines method which returns a list with each line of the file as a list item.
Next the for loop iterates through each item of the file which is basically integer one per line
It adds each item of list i.e. each integers in a line to a list using append() method.
Then the function returns the list which is the list of integers in the file.
The program along with it output is attached. The file "file.txt" contains integers 1 to 8 one per line.

Describe how asymmetric encryption is used to send a message from User A to User B that assures data confidentiality, authentication, and integrity. Be specific as to the keys used and how they achieve the three goals.
Answer:
Find the explanation below.
Explanation:
Asymmetric encryption is a system of communication in technology between two parties where keys which are variable values coined by an algorithm are used to encrypt and decrypt the messages between the sender and receiver. The two types of keys used in this process are the public and private keys. The public keys can be used by anyone to encrypt messages which are then sent to the receiver who decrypts the message using his private keys. The private keys on the other hand are only shared by the person who first set up the key. In sending messages this way, the receiver's public key is gotten from a public directory, and the message encrypted by the sender. The receiver can then decrypt the message using his private keys. But if the message is encrypted using a private key, it is decrypted by the receiver with a public key.
The one-way nature of this style of communication ensures data integrity and confidentiality since users are not required to disclose their keys and only the two parties can access the message. The two end users also preserve the right to authenticate the keys. The transport layer security protocol makes use of asymmetric encryption.
Which of the following statements is correct? Group of answer choices An object of type Employee can call the setProjectName method on itself. The Employee class's setDepartment method overrides the Programmer class's setDepartment method. An object of type Programmer can call the setDepartment method of the Employee class on itself. An object of type Employee can call the setDepartment method of the Programmer class on itself.
Answer:
An object of type Employee can call the setDepartment method of the Programmer class on itself
Explanation:
From what can be inferred above, the programmer class is a subclass of the employee class meaning that the programmer class inherits from the employee class by the code:
Public class Programmer extends Employee
This therefore means(such as in Java) that the programmer class now has access to the methods and attributes of the employee class, the superclass which was inherited from
