Given a variable n
If n is an integer, Return a string with dash'-'marks before and after each odd integer, but do not begin or end the
string with a dash mark. If n is negative, then the negative sign should be removed
If n is not an integer, return an empty value
EXAMPLES:
dashatize(274) -> '2-7-4'
dashatize(6815) -> '68-1-5'
