Print Fibonacci Series | Dataford Interview Questions

Druva QA tooling needs a predictable Fibonacci sequence for validating backup scheduling and health-check calculations. Given a non-negative integer n, return the first n Fibonacci numbers, starting with 0, 1.

Each number after the first two is the sum of the previous two numbers. Return an empty list when n is 0.

Formal Specification

Implement fibonacci(n), where:

Input: An integer n representing the requested sequence length.
Output: A list of exactly n integers containing the Fibonacci sequence from index 0 through index n - 1.

Constraints

0 <= n <= 30
n is an integer
Return exactly n Fibonacci values
Use F(0) = 0 and F(1) = 1

Function Signature

def fibonacci(n):
