Function malachite_base::slices::slice_leading_zeros

pub fn slice_leading_zeros<T: Eq + Zero>(xs: &[T]) -> usize

Counts the number of zeros that a slice starts with.

Worst-case complexity

$T(n) = O(n)$

$M(n) = O(1)$

where $T$ is time, $M$ is additional memory, and $n$ is xs.len().

Examples

use malachite_base::slices::slice_leading_zeros;

assert_eq!(slice_leading_zeros::<u32>(&[1, 2, 3]), 0);
assert_eq!(slice_leading_zeros::<u32>(&[0, 0, 0, 1, 2, 3]), 3);
