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: [53, 456, 388, 446, 83, 84, 354, 428, 431, 107, 319, 476, 345, 413, 213, 404, 278, 462, 61, 482]
