Tell me about how you would implement the Fibonacci series and verify it with a few test cases.
Implement def fibonacci(n):, returning a list containing the first n Fibonacci numbers, starting with 0, 1. For n = 0, return an empty list; for example, n = 5 returns [0, 1, 1, 2, 3], and n = 1 returns [0]. Assume 0 <= n <= 1000.
def fibonacci(n):
