dashInsert.js

// Using the JavaScript language, have the function DashInsert(num) insert dashes ('-') between each two odd numbers in num. 
// For example: if num is 454793 the output should be 4547-9-3. Don't count zero as an odd number.

// Input = 99946      Output = "9-9-946"
// Input = 56730      Output = "567-30"
