Fibonacci Sequence Coding

EasyPython

Problem

Corteva Agriscience can use simple numerical sequences when modeling recurring growth patterns. Given a non-negative integer n, generate the first n values of the Fibonacci sequence.

The sequence is defined as F(0) = 0, F(1) = 1, and F(k) = F(k - 1) + F(k - 2) for k >= 2.

Formal Specification

Implement fibonacci(n):

  • Input: An integer n representing the number of sequence values to return.
  • Output: A list containing F(0) through F(n - 1) in order.
  • Return an empty list when n is 0.
  • Use an iterative approach that avoids recomputing earlier values.

Constraints

  • 0 <= n <= 100
  • n is an integer
  • Return exactly n values
  • The sequence starts with F(0) = 0 and F(1) = 1
