Answer:
You forgot to add a group of choices, however assuming this programming language uses 0-based indexes the answer would be x - 1
Explanation:
Zero based index languages have array indexes starting at 0. When you create that array, you use x to define the amount of elements, however due to the array starting at the index 0, the arrays highest index would be x - 1 instead of x.
One way could be to check the code of the program.
But of course this might not be possible... Not everyone knows a programming language. And even if you did, you might not know the programming language they used.
Another way is to download a program that monitors your incoming connections and outgoing connections from your computer/android/iphone.
When someone or something connects to your device, the program should alert you. Or when the computer makes a connection to a website/device.
An “iframe” maybe idk what is asking
Answer:
import math
def isPrime(num):
if num % 2 == 0 and num > 2:
return False
for i in range(3, int(math.sqrt(num)) + 1, 2):
if num % i == 0:
return False
return True
Explanation:
The solution is provided in the python programming language, firstly the math class is imported so we can use the square root method. The first if statement checks if the number is even and greater than 2 and returns False since all even numbers except two are not prime numbers.
Then using a for loop on a range (3, int(math.sqrt(num)) + 1, 2), the checks if the number evenly divides through i and returns False otherwise it returns True
