The simplest way to start thinking about an array is as a collection, or a set of elements. In programming, these elements may be constants, variables, functions and pointers.

Question

Implement the following C code in RISC-V assembly. Hint: Remember that the stack pointer must remain aligned on a multiple of 16.

```c
int fib(int n) {
if (n == 0)
return 0;
else if (n == 1)
return 1;
else
return fib(n-1) + fib(n-2);
}
```

### Description

This code is a recursive implementation of a function in C that calculates the Fibonacci number for a given integer $ n $.

#### Explanation:

- **Function Definition**: `int fib(int n)` declares a function named `fib`, which takes an integer `n` as input and returns an integer.

- **Base Cases**:
- If `n` is 0, the function returns 0.
- If `n` is 1, the function returns 1.

- **Recursive Case**:
- For all other values of `n`, the function returns the sum of the Fibonacci numbers of the two preceding numbers: `fib(n-1)` and `fib(n-2)`.

This implementation follows the mathematical definition of the Fibonacci sequence, where each number is the sum of the two preceding ones, usually starting with 0 and 1. The function uses recursion to break down the problem into smaller subproblems.
