Fibonacci Sequence Printing | Dataford Interview Questions

Write a function that prints out the Fibonacci sequence.

For deterministic grading, implement this as fibonacci(n), which returns the first n terms as a space-separated string with no trailing space. Return an empty string when n is zero.

Input: A non-negative integer n.

Output: A string containing the first n Fibonacci terms, starting with 0, 1.

Constraints

0 <= n <= 1000
The sequence starts with 0 and 1
Terms are separated by one space with no trailing space

Function Signature

def fibonacci(n):
