alexira [117]

Answer:

In Python:

low = int(input("Low: "))

high = int(input("High: "))

if low >= 1000000000 or high >=1000000000:

   print("Out of range")

else:

   mylist = []

   for num in range(low,high+1):

       flag = False

       if num > 1:

           for i in range(2, num):

               if (num % i) == 0:

                   flag = True

                   break

       if not flag:

           mylist.append(num)

           print(num, end = " ")

   print()

   print("The twin primes are: ",end="")

   count = 0

   for i in range(1,len(mylist)):

       if mylist[i] - mylist[i-1] == 2:

           print(str(mylist[i])+" & "+str(mylist[i-1]),end=", ")

What are the differences and similarities of computer virus and biological virus. Give 4 examples
Papessa [141]

Answer:

During recent months, we’ve witnessed an unexpected and distressing pandemic of a coronavirus disease. What I find especially distressing about it is how the worldwide adversity was caused by just a tiny thing — namely, a virus called SARS-CoV-2.

However, biological viruses have always been a potent threat to humanity, as historic pandemics have proved. No wonder viruses became an ideal weapon model in a totally different world — a world of programming. The first computer viruses were created as early as in the 1970s. Starting as pranks, they evolved to become a major threat to the stability of computer networks worldwide. And the more I think of viruses, both biological and digital, the more amazed I am by their similarities.

We don’t know what kind of challenges viruses of either type will cause in the future, but understanding how they infect, the symptoms they induce, how they spread, and the damage they can cause can help us fight both.

The Common Thread

Let’s start with the basics: What does a virus look like?

computer virus of 1999

Figure 1: Pictured on the left is an electron microscope image of SARS-CoV-2 particles - the pandemic-causing coronavirus. Source: NIAID-RML. Pictured on the right is a code snippet of a Melissa, the notorious email-spreading computer virus of 1999. Source: Gizmodo.

The images in Figure 1 might look vastly different, but, essentially, they’re the same: a string of code. In the coronavirus, it’s the RNA genome in a shell; in Melissa, it’s computer code. In both cases, the code is an “instruction” for the virus to follow.
