So I added only one element. I could change it so I add more then just a for loop to pop multiple added elements. When you add to the list it gets added to the head, so I checked the 0 index for the difference. If I checked the last element then for one of the cases it could be out of range. -- This is an automated message from the Apache Git Service.
