No return value here so when the reursed function returns carryover
we have nowhere to go in the calling function so we return None.
else:
return carryover
This returns a value to the calling function, but in
the recursive case that returned vaklue uis thrown away
as the comment above shows.
you need to add a return statement where you call recursively.
