A Short Fibonacci Sequence

Welcome to A Short Fibonacci Sequence on Exercism's Rust Track. If you need help running the tests or submitting your code, check out HELP.md. If you get stuck on the exercise, check out HINTS.md, but try and solve it without using those first :)

Introduction

Rust provides a macro vec![] to help you create Vectors. This comes in quite handy when you need to initialize lists.

Instructions

You are going to initialize empty buffers and list the first five numbers, or elements, of the Fibonacci sequence.

The Fibonacci sequence is a set of numbers where the next element is the sum of the prior two. We start the sequence at one. So the first two elements are 1 and 1.

1. Create a buffer of count zeroes.

Create a function that creates a buffer of count zeroes.

let my_buffer = create_buffer(5);
// [0, 0, 0, 0, 0]

2. List the first five elements of the Fibonacci sequence

Create a function that returns the first five numbers of the Fibonacci sequence. Its first five elements are 1, 1, 2, 3, 5

let first_five = fibonacci();
// [1, 1, 2, 3, 5]
