# Leetcode - Subtract the Product and Sum of Digits of an Integer Solution

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`

## Solution in Python

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