fun fibonacci(n: u64) u64 {
    var a: u64 = 0;
    var b: u64 = 1;
    var i: u64 = 0;
    for (i < n) {
        val t: u64 = b;
        b = a + b;
        a = t;
        i = i + 1;
    }
    ret a;
}

#[symbol("main")]
fun main(argc: i64, argv: **u8) i64 {
    print.printlnf("fib(10) = {}", fibonacci(10));
    ret 0;
