In this task, you are given a list of integers you need to calculate and return the range of the integers which is the difference between maximum and minimum element in the list.

Let me give you an example: [1,2,3,4,5,7,34,25]
The answer to this example can be: 33
Here is why: maximum element is 34 and minimum element is 1, range is equal to the difference between 34 and 1 which is 33.

OK. solve this:
[92, 439, 231, 76, 136, 498, 129, 426, 186, 252, 120, 314, 53, 131, 258, 45, 36, 239, 449, 321]
Answer:
462
