Teacher: 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.
Teacher: Now, understand the problem? If you are still confused, see the following example:
[1,2,3,4,5,7,34,25]
Solution: 33
Reason: maximum element is 34 and minimum element is 1, range is equal to the difference between 34 and 1 which is 33.

Now, solve this instance: [279, 232, 368, 498, 109, 256, 237, 489, 381, 299, 440, 225, 182, 307, 58, 39, 173, 228, 485, 212]
