generally to collect items you need is faster than remove what you don’t need. but of course it depends on how many items you need remove and save

If you simply want to remove the interval from the array of sorted integers that appear only once I’d suggest to use bitarrays instead

You can also remove item by reverse iteration:
clearlistener()
TheArray = for i = 1 to 9 collect i
for i = 8 to 5 by -1 do deleteitem TheArray i
