import java.util.Scanner;

public class New

{

public static void main(String[] args)

{

int num;

int prime;

Scanner var=new Scanner(System.in);

System.out.println("Enter a number: ");

num=var.nextInt();

for(int i=2;i<num;i++)

{

prime=0;

for(int j=2;j<i;j++)

{

if(i%j==0)

prime=1;

}

if(prime==0)

System.out.println(i);

}

Explanation:

Using Java Programming Language the program as implemented above will prompt a user to enter a number, for example the user enters 5,

It will print

which are the prime numbers up to the integer 5

What is a man-in-the-middle attack

VMariaS [17]

Answer: An attack where the attackers will interrupt a data transfer happening between parties and in which they will pretend to be the legitimate parties.

Explanation: For example think about two people writing letters to each other back and forth. However you, the attacker can intercept the letters and effectively change the message/contents of the letter going to the other person. This is probably not the best explanation, but simply put a man-in-the-middle attack is when an attacker interupts a transfer and pretends to be the legitimate source.

Using recursion, write a program that asks a user to enter the starting coordinates (row, then column), the ending coordinates (

Luden [163]

Answer:

The program in Python is as follows

def Paths(row,col):

if row ==0 or col==0:

return 1

return (Paths(row-1, col) + Paths(row, col-1))

row = int(input("Row: "))

col = int(input("Column: "))

print("Paths: ", Paths(row,col))

Explanation:

This defines the function

def Paths(row,col):

If row or column is 0, the function returns 1

if row ==0 or col==0:

return 1

This calls the function recursively, as long as row and col are greater than 1

return (Paths(row-1, col) + Paths(row, col-1))

The main begins here

This prompts the user for rows

row = int(input("Row: "))

This prompts the user for columns

col = int(input("Column: "))

This calls the Paths function and prints the number of paths

print("Paths: ", Paths(row,col))

Consider the Google Trends graph of dogs and cats. Give a plausible explanation or hypothesis for the spike in dog searches that

Nataly [62]

Answer:

The correct answer for: Consider the Google Trends graph of dogs and cats. Give a plausible explanation or hypothesis for the spike in dog searches that occurred between 2014 and 2015 that would lead to further investigation or research. Give your explanation and what you would want to investigate next. Is: b. dog rescues someone.

Explanation:

All right. The topic I would lie t investigate next is dogs rescue someone. Because first of all, the word dog by itself wouldn't generate such a spike in searches. c) option new dog breed seems quite difficult because for a new dog breed to be created. There has to be a hundred-year period to make the genetic design and also it has to be allowed by the kennel club as well as organizations that seek for dog's health and wellbeing. That leaves dog attack and dog rescues someone in the final mile. A dog attack is something not very common but that happens. Nevertheless, even though it is relevant it wouldn't as impressive and pivoting as a dog rescuing someone. The reason behind my posture is that as a story is not very promising, it could be a little bit yellow journalism and won't be as accepted and shared as a good act from a dog.
