Given the task definition, example input & output, solve the new input case.
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.
Example: [1,2,3,4,5,7,34,25]
Output: 33
maximum element is 34 and minimum element is 1, range is equal to the difference between 34 and 1 which is 33.

New input case for you: [73, 222, 89, 56, 211, 16, 409, 136, 12, 153, 285, 109, 466, 474, 290, 408, 54, 379, 220, 309]
