Implement IEnumerable With yield

Write a Countdown class that implements IEnumerable<int>. Given a start value in its constructor, iterating it with foreach must produce the numbers from start down to 1. Implement both the generic GetEnumerator() (using yield return) and the non-generic one required by IEnumerable. Do NOT write a Main method.

For new Countdown(3) the program prints:
3
2
1

Expected Output:

3
2
1
