Line 2,894:
pub fn main() {
println!("{}", a(10, &1, &-1, &-1, &1, &0));
}</lang>
Another solution where we have B take itself as an argument in order to recursively call itself:
<lang rust>use std::cell::Cell;
fn a(k: i32, x1: &Fn() -> i32, x2: &Fn() -> i32, x3: &Fn() -> i32, x4: &Fn() -> i32, x5: &Fn() -> i32) -> i32 {
let k1 = Cell::new(k);
struct B<'a> { f: &'a Fn(&B) -> i32 }
let b = B {
f: &|b| {
k1.set(k1.get() - 1);
return a(k1.get(), &||(b.f)(b), x1, x2, x3, x4)
}
};
let b = ||(b.f)(&b);
if k <= 0 {
return x4() + x5()
} else {
return b()
}
}
pub fn main() {
println!("{}", a(10, &||1, &||-1, &||-1, &||1, &||0));
}</lang>
