$6\mathrm{.}4\mathrm{.}3$: Compute the distance between element positions.

Compute the distance between the positions of the first and last zero element in the given array. For example, if the array is

$301049506$ your algorithm should yield $7-1=6.$

If the array contains a single zero, return $0.$ If it doesn't contain any zeroes, return a negative value.
