Q6. addToInventory Write a static method addToInventory that takes two arguments, inventory and shipment, both of which are TreeMap. These maps show the number of each item in an inventory and a shipment. The method adds the shipment to the inventory, leaving the shipment unchanged. The method doesn't return anything, just updates the inventory argument.
