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: [21, 128, 318, 367, 66, 190, 441, 186, 206, 52, 325, 467, 429, 167, 482, 464, 389, 60, 306, 146]
