A permutation of length n is an ordering of the positive integers {1,2,.,n}. For example, n=(5,3,2,1,4) is a permutation of length 5. Write a Python script to solve the following, A positive integer ns7. Given: Return: The total number of permutations of length n, followed by a list of all such permutations (in any order). Sample Dataset: 3 Sample Output: 6 123 132 213 231 312 321 Your script should output the data in the same format as indicated here to the terminal/console. It will receive the value of n from the user via the terminal/console.

Transcribed Image Text:A permutation of length \( n \) is an ordering of the positive integers \(\{1,2,\ldots,n\}\). For example, \(\pi=(5,3,2,1,4)\) is a permutation of length 5.
Write a Python script to solve the following,
**Given:**
A positive integer \( n \leq 7 \).
**Return:**
The total number of permutations of length \( n \), followed by a list of all such permutations (in any order).
**Sample Dataset:**
```
3
```
**Sample Output:**
```
6
1 2 3
1 3 2
2 1 3
2 3 1
3 1 2
3 2 1
```
Your script should output the data in the same format as indicated here to the terminal/console. It will receive the value of \( n \) from the user via the terminal/console.
