Write a Python program to sort a list of elements using the Radix sort in descending order.

According to Wikipedia "In computer science, radix sort is a non-comparative integer sorting algorithm that sorts data with integer keys by grouping keys by the individual digits which share the same significant position and value".

Your input : `[95, 38, 25, 168, 347]`

Note: Try solving this with RadixSort. This problem is meant for you to learn the implementation of the Radix Sort Algorithms. Hence, this problem would not earn you any Domes ( DomeCode points ). Attempt this if you care about the implementation.
