// Write a function insertDash(num) that will 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.

// My Solution:

function insertDash(num) {
   var arr1=num.toString().split("")
   console.log(arr1)
  for (var i=0; i<arr1.length; i++){
      if ((arr1[i]%2===1) && (arr1[i+1]%2===1)){
          arr1.splice(i+1,0,"-")
      }
      console.log(arr1)
  }
  arr1=arr1.join("")
  return arr1
 
}

insertDash(454793)

// Test.assertEquals(insertDash(454793),'4547-9-3');
// Test.assertEquals(insertDash(123456),'123456');
// Test.assertEquals(insertDash(1003567),'1003-567');
