Teacher: In this task, you are given a list of unique integers you need to swap the positions of maximum and minimum element in the list and return the updated list.
Teacher: Now, understand the problem? If you are still confused, see the following example:
[1,45,67,43,58,98,41,34,57]
Solution: [98,45,67,43,58,1,41,34,57]
Reason: 1 is the minimum element and 98 is the maximum element and their positions are swapped in the resulting list.

Now, solve this instance: [133, 356, 66, 449, 397, 410, 374, 329, 279, 40, 169, 82, 75, 19, 186, 65, 61, 414, 243, 30]
