Given a number **N **, calculate total number of permutations of it and also the sum of all permutations including that number itself.

**Example 1:**

**Input: **N = 5
**Output: **1 5
**Explanation: **There is only one permutation
of 5 and sum of this permutaion is 5.

**Example 2:**

**Input: **N = 12
**Output: **2 33
**Explanation: **Permutations of 12 are 12 and 21.
Sum of these permutations are = 12 + 21 = 33.

**Your Task:**

You don't need to read or print anyhting. Your task is to complete the function **permutation()** which takes N as input parameter ans returns a list that contains total number of permutations and sum of all these permutations including the number iteself.

**Expected Time Complexity: **O(K!) where K = log_{10}N

**Expected Space Complexity: **O(1)

**Constraints:**

1 <= N <= 10^{5}

Here is some troubleshooting advice:

- Reset the IDE using the second button on the top right corner.
- Avoid using static/global variables in your code as your code is tested against multiple test cases and these tend to retain their previous values.
- Passing the Sample/Custom Test cases does not guarantee the correctness of code. On submission, your code is tested against multiple test cases consisting of all possible corner cases and stress constraints.
- You can access the hints to get an idea about what is expected of you as well as the final solution code.
- You can view the solutions submitted by other users from the submission tab.
