Check whether the sum of absolute difference of adjacent digits is Prime or not in Python

Suppose we have a number n. We have to check whether the sum of the absolute difference of adjacent digit pairs is prime or not.

So, if the input is like n = 574, then the output will be True as |5-7| + |7-4| = 5, this is prime.

To solve this, we will follow these steps −

• num_str := n as string
• total := 0
• for i in range 1 to size of num_str - 1, do
  • total := total + |digit at place num_str[i - 1] - digit at place num_str[i]|
• if total is prime, then
  • return True
• return False

Let us see the following implementation to get better understanding −

def isPrime(num):    if num > 1:       for i in range(2, num):          if num % i == 0:            return False       return True    return False       def solve(n):    num_str = str(n)    total = 0    for i in range(1, len(num_str)):       total += abs(int(num_str[i - 1]) - int(num_str[i]))            if isPrime(total):       return True    return False       n = 574 print(solve(n))
