Function malachite_nz::integer::exhaustive::exhaustive_nonzero_integers

pub fn exhaustive_nonzero_integers() -> IntegerUpDown

Generates all nonzero Integers, in order of increasing absolute value. When two Integers have the same absolute value, the positive one comes first.

The output length is infinite.

Worst-case complexity per iteration

$T(i) = O(i)$

$M(i) = O(1)$, amortized.

where $T$ is time, $M$ is additional memory, and $i$ is the iteration number.

Examples

use malachite_base::iterators::prefix_to_string;
use malachite_nz::integer::exhaustive::exhaustive_nonzero_integers;

assert_eq!(
    prefix_to_string(exhaustive_nonzero_integers(), 10),
    "[1, -1, 2, -2, 3, -3, 4, -4, 5, -5, ...]"
)
