Name: Digit power sum
Problem Statement: The number 512 is interesting because it is equal to the sum of its digits raised to some power: 5 + 1 + 2 = 8, and 83 = 512. Another example of a number with this property is 614656 = 284.
We shall define an to be the nth term of this sequence and insist that a number must contain at least two digits to have a sum.
You are given that a2 = 512 and a10 = 614656.
Find a30

* chore: update print_reverse helper method
Use a generator expression instead of slicing
`elements_list` to improve the space and time complexity
of `make_linked_list` to O(1) space and O(n) time
by avoiding the creation a shallow copy of `elements_list`.
* fix: add type checking and argument typing
Add argument typing to all methods in `print_reverse`
Add doctest to helper function `make_linked_list` and
basic edge case tests to `print_reverse`
* test: add `print_reverse` test
Fix doctest syntax and remove edge case tests that are covered
by typed arguments.
Add `print_reverse` test that expects the correct values are printed
out by adding a `test_print_reverse_output` helper function.
* format code
