It is a function that accepts a list of integers sorted in increasing order and another integer to insert into that list.

This is what I have so far:

```
def insert_sorted():
user_array = 0
array = input("Please insert a list")
user_array = input("Please insert an integer to add to the list")
return list.insert()
```

This is the output I’m looking for:

```
>>> array = [1, 4, 5, 9, 13, 15]
>>> insert_sorted(array, 6)
>>> array
[1, 4, 5, 6, 9, 13, 15]
```
