Suppose we wish to sort the following array of 3-digit numbers: A = [329, 457, 657, 839, 436, 720, 355]. The Radix Sort algorithm works as follows: we use any stable sorting algorithm (e.g. Count- ing Sort) to sort the array by their third digit, and then use this stable sorting algorithm to sort the updated array by their second digit, and finally use this stable sorting algorithm to sort the updated array by their first digit. Here is an illustration of the Radix sort algorithm on the above input of seven numbers: 329 720 720 329 457 355 329 355 657 436 436 436 839 . 457 ., 839 ... 457 436 657 355 657 720 329 457 720 355 839 657 839 For any input array of n 3-digit numbers, prove that Radix Sort is guaranteed to correctly sort these n numbers, with the algorithm running in O(n) time.

Suppose we wish to sort the following array of 3-digit numbers: A = [329, 457, 657, 839, 436, 720, 355].
The Radix Sort algorithm works as follows: we use any stable sorting algorithm (e.g. Count-
ing Sort) to sort the array by their third digit, and then use this stable sorting algorithm to sort
the updated array by their second digit, and finally use this stable sorting algorithm to sort the
updated array by their first digit.
Here is an illustration of the Radix sort algorithm on the above input of seven numbers:

For any input array of n 3-digit numbers, prove that Radix Sort is guaranteed to correctly sort
these n numbers, with the algorithm running in O(n) time.
