    1281 - Subtract the Product and Sum of Digits of an Integer.

    Easy

    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
