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


给你一个整数 n,请你帮忙计算并返回该整数「各位数字之积」与「各位数字之和」的差。

 

示例 1:

输入:n = 234
输出:15
解释:
各位数之积 = 2 * 3 * 4 = 24
各位数之和 = 2 + 3 + 4 = 9
结果 = 24 - 9 = 15
示例 2:

输入:n = 4421
输出:21
解释:
各位数之积 = 4 * 4 * 2 * 1 = 32
各位数之和 = 4 + 4 + 2 + 1 = 11
结果 = 32 - 11 = 21
 

提示:

1 <= n <= 10^5
