DashInsertII.js

/*
Using the JavaScript language, have the function DashInsertII(num) 
insert dashes ('-') between each two odd numbers and insert asterisks 
('*') between each two even numbers in num. For example: if num is 
4546793 the output should be 454*67-9-3. Don't count zero as a negative 
or positive number.
