Prime numbers can be generated by an algorithm known as the Sieve of Eratosthenes. The algorithm for this procedure is presented here. Write a program called primes.js that implements this algorithm. Have the program find and display all the prime numbers up to n = 150
Answer:
Explanation:
The following code is written in Javascript and is a function called primes that takes in a single parameter as an int variable named n. An array is created and looped through checking which one is prime. If So it, changes the value to true, otherwise it changes it to false. Then it creates another array that loops through the boolArray and grabs the actual numberical value of all the prime numbers. A test case for n=150 is created and the output can be seen in the image below highlighted in red.
function primes(n) {
//Boolean Array to check which numbers from 1 to n are prime
const boolArr = new Array(n + 1);
boolArr.fill(true);
boolArr[0] = boolArr[1] = false;
for (let i = 2; i <= Math.sqrt(n); i++) {
for (let j = 2; i * j <= n; j++) {
boolArr[i * j] = false;
}
}
//New Array for Only the Prime Numbers
const primeNums = new Array();
for (let x = 0; x <= boolArr.length; x++) {
if (boolArr[x] === true) {
primeNums.push(x);
}
}
return primeNums;
}
alert(primes(150));
The development of the modern computer system has been evolutionary. Discuss this phenomenon and further discuss how current trends in computing would impact future computer systems development
Answer:
The modern computer system has been evolutionary. Modern computers have allowed for us to complete hard tasks rather easily. With modern computers, we are able to calculate advanced equations with the click of a button. Trends in computing like RTX can rapidly improve performance, rendering, and tons of other graphical heavy actions. In September of 2018, we got the first RTX card, now in 2021, RTX has become exponentially better than what it was in 2018. With the modern computers comes quantum computers. Quantum computing is estimated to be 100 million times faster than any modern computer. IBM, the company to make the first computer stated that we are in the decade of quantum computing. And who knows? Maybe quantum computing will come sooner rather than later.

Leo is planning the new backup strategy for a subsidiary his company is purchasing that does not currently have a backup strategy in place. He decides that a full backup should be run once per week. Once per day, everything that has changed since the last full backup will be archived. Once per hour everything that has changed since the last backup of any type will be backed up. Which of the following describes the backups that will be run every hour?
a. Differential
b. Variable
c. Incremental
d. Flexible
Answer:
C. Incremental backup
Explanation:
An incremental backup is a type of backup where the succeeding copies of the data is made up of only those positions that have changed since the previous or prior copies were made. Such backups are desired since they limit the usage of space for storage and these types of back ups are faster to do that the differential backup.
When we bring this explanation to this question, we can easily see that the backup that is being carried out is done on everything that has changed since the last backup (previous backup). Therefore this is an incremental backup.

Suppose you have some List of S List of Strings called List and a String prefix. Write a method that removes all the Strings from list that begin with prefix. public void removePrefixStrings(List-String- list, String prefix) 7. What is the time complexity of this algorithm?
Answer:
public void removePrefixStrings(List<String> list , String prefix) {
if(list==null || list.size()==0)
return;
for(int i=0; i<list.size();) {
if(list.get(i).startsWith(prefix))
list.remove(i);
else
++i;
}
}
Time Complexity: If the prefix is the same as String length, Then finding all prefix match will take n *n = n2
Then removal is also n
So the total time complexity is O(n3)
Write a program that asks the user to enter 5 test scores. The program will display a letter grade for each test score and an average grade for the test scores entered. Three functions are needed for this program.
Answer:
The program in C++ is as follows:
#include <iostream>
using namespace std;
double average(double s1, double s2, double s3, double s4, double s5){
double avg = (s1 + s2 + s3 + s4 + s5)/5;
return avg;}
char lGrade(double score){
char grade;
if(score>= 90 && score <= 100){ grade ='A'; }
else if(score>= 80 && score <= 89){ grade ='B'; }
else if(score>= 70 && score <= 79){ grade ='C'; }
else if(score>= 60 && score <= 69){ grade ='D'; }
else if(score < 60){ grade ='F'; }
return grade;}
int main(){
double s1,s2,s3,s4,s5;
cin>>s1>>s2>>s3>>s4>>s5;
double avg = average(s1,s2,s3,s4,s5);
cout<<s1<<" "<<lGrade(s1)<<endl;
cout<<s2<<" "<<lGrade(s2)<<endl;
cout<<s3<<" "<<lGrade(s3)<<endl;
cout<<s4<<" "<<lGrade(s4)<<endl;
cout<<s5<<" "<<lGrade(s5)<<endl;
cout<<avg<<" "<<lGrade(avg)<<endl;
return 0;}
Explanation:
The three functions to include in the program are not stated; so, I used the following functions in the program
1. The main function
2. average function
3. Letter grade function
The average function begins here
double average(double s1, double s2, double s3, double s4, double s5){
This calculates the average
double avg = (s1 + s2 + s3 + s4 + s5)/5;
This returns the calculated average
return avg;}
The letter grade function begins here
char lGrade(double score){
This declares the grade
char grade;
If score is between 90 and 100 (inclusive), grade is A
if(score>= 90 && score <= 100){ grade ='A'; }
If score is between 00 and 89 (inclusive), grade is B
else if(score>= 80 && score <= 89){ grade ='B'; }
If score is between 70 and 79 (inclusive), grade is C
else if(score>= 70 && score <= 79){ grade ='C'; }
If score is between 60 and 69 (inclusive), grade is D
else if(score>= 60 && score <= 69){ grade ='D'; }
If score is less than 60, grade is F
else if(score < 60){ grade ='F'; }
This returns the calculated grade
return grade;}
The main begins here
int main(){
This declares the 5 scores
double s1,s2,s3,s4,s5;
This gets input for the 5 scores
cin>>s1>>s2>>s3>>s4>>s5;
This calls the average function for average
double avg = average(s1,s2,s3,s4,s5);
This calls the letter grade function for the 5 scores
cout<<s1<<" "<<lGrade(s1)<<endl;
cout<<s2<<" "<<lGrade(s2)<<endl;
cout<<s3<<" "<<lGrade(s3)<<endl;
cout<<s4<<" "<<lGrade(s4)<<endl;
cout<<s5<<" "<<lGrade(s5)<<endl;
This calls the average function for the average
cout<<avg<<" "<<lGrade(avg)<<endl;
1) Declare an ArrayList named numberList that stores objects of Integer type. Write a loop to assign first 11 elements values: 1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024. Do not use Math.pow method. Assign first element value 1. Determine each next element from the previous one in the number List. Print number List by using for-each loop.
Answer:
Explanation:
The following is written in Java and uses a for loop to add 10 elements to the ArrayList since the first element is manually added as 1. Then it calculates each element by multiplying the previous element (saved in count) by 2. The program works perfectly and without bugs. A test output can be seen in the attached image below.
import java.util.ArrayList;
class Brainly {
public static void main(String[] args) {
ArrayList<Integer> numberList = new ArrayList<>();
numberList.add(0, 1);
int count = 1;
for (int i = 1; i < 11; i++) {
numberList.add(i, (count * 2));
count = count * 2;
}
for (Integer i : numberList) {
System.out.println(i);
}
}

If i took my SIM card out of my phone and put it in a router then connect the router and my phone with Ethernet cable would the ping change?
Answer:
The ping will change.
Explanation:
Assuming you mean ping from device with SIM card to another host (no mater what host), the ping will change. Ping changes even on the same device because network speed and performance of all the nodes on the route changes continuously. However, if two of your devices (phone & router) are configured differently (use different routing under the hood), then it will also affect the ping.

a. Continuity
b. Adaptability
c. Vertical scaling
d. Horizontal scaling
Answer:
The description of this capability is:
d. Horizontal scaling
Explanation:
The capability that Brandon has achieved is horizontal scaling, which involves the increasing of the resources of cloud applications to meet his increasing demand for cloud services. Vertical scaling involves the addition or subtraction of power to a cloud server, which practically upgrades the memory, storage, or processing power. But to scale horizontally, more resources are added or subtracted. The purpose of horizontal scaling is to spread out or in the workload of existing resources and either increase or decrease overall performance and capacity.
