In stack we can access elements from both ends
o true
o false

False

Explanation:

The answer is False. In Stacks, we can access only the top element present in the stack. Stack is the collection of elements which follow LIFO ( Last In First Out ) which means the last element inserted in the stack is the first element to  out. Stack has restriction that only the element which is present at the top called as top element is only accessible. That means only the top element can be inserted and deleted.
