## Fibonacci Number
Write a function called `fibonacci` that takes a non-negative integer `n` as input and returns the **n-th Fibonacci number**.
The Fibonacci sequence is defined as:
* `F(0) = 0`
* `F(1) = 1`
* `F(n) = F(n-1) + F(n-2)` for `n > 1`
### Function Signature:
```python
def fibonacci(n):
# return your solution
```
#### Requirements
* The function should return the `n`-th number in the Fibonacci sequence.
* If `n` is less than `0`, print `"Incorrect input"`.
* Your function will be tested with:
* Base cases (`n = 0` and `n = 1`)
* Small values of `n`
* Larger values of `n` (e.g., 9)
* Multiple test cases in sequence
#### Example:
```python
fibonacci(0) # returns 0
fibonacci(1) # returns 1
fibonacci(2) # returns 1
fibonacci(3) # returns 2
fibonacci(5) # returns 5
fibonacci(9) # returns 34
```
You can copy this into your problem’s solution description.
