fn test_full() {
assert_eq!(fib(0), 0);
assert_eq!(fib(1), 1);
assert_eq!(fib(2), 0 + 1);
assert_eq!(fib(3), 1 + 1);
assert_eq!(fib(4), 1 + 2);
assert_eq!(fib(5), 2 + 3);
assert_eq!(fib(6), 3 + 5);
assert_eq!(fib(7), 5 + 8);
assert_eq!(fib(8), 8 + 13);
assert_eq!(fib(9), 13 + 21);
assert_eq!(fib(10), 21 + 34);
assert_eq!(fib(11), 34 + 55);
assert_eq!(fib(12), 55 + 89);
assert_eq!(fib(13), 89 + 144);
}

Целта на това първо предизвикателство е да имплементирате функция, която връща поредното число от редицата на фибоначи, с първи индекс 0. Тоест,

  • С вход 0, функцията се очаква да върне 0
  • С вход 1, функцията се очаква да върне 1
  • С какъвто и да е друг вход, функцията връща сумата на предните две числа на фибоначи.

Заместете todo!() със своята имплементация на тази функция:

pub fn fib(n: u32) -> u32 {
    todo!()
}
