Which of the following is NOT a characteristic of a stack?

Step 1: Understand what a stack is. A stack is a data structure that stores items in a specific order.
Step 2: Learn about the Last In First Out (LIFO) principle. This means the last item added to the stack is the first one to be removed.
Step 3: Recognize that stacks do not allow random access. You cannot access an item in the middle of the stack; you can only access the top item.
Step 4: Identify characteristics of stacks. They allow adding (push) and removing (pop) items only from the top.
Step 5: Determine which option does not fit the characteristics of a stack. Look for something that suggests random access or a different order of operation.
