[Solved] Given an integer number n, return the difference between the product of its digits and the sum of its digits.

Question

Given an integer number n, return the difference between the product of its digits and the sum of its digits.

Example 1:

Input: n = 234
Output: 15 
Explanation: 
Product of digits = 2 * 3 * 4 = 24 
Sum of digits = 2 + 3 + 4 = 9 
Result = 24 - 9 = 15

Example 2:

Input: n = 4421
Output: 21
Explanation: 
Product of digits = 4 * 4 * 2 * 1 = 32 
Sum of digits = 4 + 4 + 2 + 1 = 11 
Result = 32 - 11 = 21

Constraints:

• 1 <= n <= 10^5

Python Solution

class Solution:
    def subtractProductAndSum(self, n: int) -> int:
        s=0
        m=1
        for  i in str(n):
            m*=int(i)
            s+=int(i)
        return m-s
