Moves the specified amount of elements to the start of the list.

- Use slice notation to get the two slices of the list and combine them before returning.

|
```py
|
|
def roll(lst, offset):
|
|
return lst[-offset:] + lst[:-offset]
|
|
```
|
|
|
|
```py
|
|
roll([1, 2, 3, 4, 5], 2) # [4, 5, 1, 2, 3]
|
|
roll([1, 2, 3, 4, 5], -2) # [3, 4, 5, 1, 2]
|
|
```
