Solution
To determine whether a given number is prime or not, follow these steps:
- Accept an integer as input.
- Check if the input number is less than or equal to 1. If it is, print "Not a Prime Number" and stop.
- Initialize a variable, let's call it "isPrime", to true.
- Iterate from 2 to the square root of the input number (inclusive).
- For each iteration, check if the input number is divisible by the current iteration number.
- If it is, set "isPrime" to false and break out of the loop.
- After the loop, check the value of "isPrime".
- If it is true, print "Prime Number".
- If it is false, print "Not a Prime Number".
Here's the code implementation in Python:
import math
def is_prime(num):
if num <= 1:
return False
is_prime = True
for i in range(2, int(math.sqrt(num)) + 1):
if num % i == 0:
is_prime = False
break
return is_prime
input_num = int(input("Enter a number: "))
if is_prime(input_num):
print("Prime Number")
else:
print("Not a Prime Number")
You can run this code and provide an integer as input to check if it is a prime number or not.

Problem statementSend feedbackYou are given a positive integer ‘N’. Your task is to print all prime numbers less than or equal to N.Note: A prime number is a natural number that is divisible only by 1 and itself. Example - 2, 3, 17, etc.You can assume that the value of N will always be greater than 1.
