+
+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

+class Solution:
+    def subtractProductAndSum(self, n: int) -> int:
+        sum, product = 0, 1
+        while n:
+          digit = n % 10
+          sum += digit
+          product *= digit
+          n //= 10
+        return product - sum
