Fulcrum def can_balance(items): Each item in the list of items is now considered to be a physical weight, and therefore guaranteed to be a positive integer. Your task is to find and return a fulcrum position in this list so that when balanced on that position, the total torque of the items to the left of that position equals the total torque of the items to the right of that position. (The item on the fulcrum is assumed to be...
