LetterInventory subtraction = new LetterInventory(""); subtraction.inventory[i] = inventory[i] - other.inventory[i]. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. In CSE 143, a common approach to reducing redunancy is simply to write a new method.
