Syntax error Check if difference of areas of two squares is prime in Python

Check if difference of areas of two squares is prime in Python

Suppose we have two numbers x and y. We have to check whether difference of their areas is prime or not.

So, if the input is like x = 7, y = 6, then the output will be True as the difference of their square is 49 - 36 = 13 which is prime.

To solve this, we will follow these steps −

  • if (x + y) is prime number and (x - y) is 1, then
    • return True
  • otherwise,
    • return False

Let us see the following implementation to get better understanding −

Example

 Live Demo

def is_prime(num) :
   if num <= 1 :
      return False
   if num <= 3 :
      return True
   if num % 2 == 0 or num % 3 == 0 :
      return False
   i = 5
   while i * i <= num:
      if num % i == 0 or num % (i + 2) == 0:
         return False
      i = i + 6
   return True
def solve(x, y):
   if is_prime(x + y) and x - y == 1:
      return True
   else:
      return False
x, y = 7, 6
print(solve(x, y))

Input

7,6
