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: [394, 96, 237, 138, 129, 418, 198, 18, 420, 465, 375, 33, 216, 59, 245, 276, 387, 144, 378, 431]
