What are the two primary stack operations?*1 pointa. Add and Subtractb. Push and Popc. Insert and Deleted. Get and Set

These operations are called on a Stack : push(8), push(1), push(6), push(7), pop(), pop(), pop(), push(2), pop(). What is the data at the top position?A7B6C8D2

Which of the following is not an operation on a stack?

Suppose someone designed a Stack data abstraction with the following operations:(a) Push: Adds an element on top of the stack.(b) Pop: Removes the top element from the stack.(c) Top: Returns a pointer to the top of the stack.Give your critical comment on the design of this data abstraction.

If the sequence of operations - push(1) push(2) pop push(1) push(2) pop pop pop push(2) pop are performed on a stack, the sequence of popped out values are ? Options 2 1 2 2 1 2 2 1 1 2 2 2 1 2 2

In stack operations, what is the primary check performed before pushing an element onto the stack?*1 pointa. Check if the stack is emptyb. Check if the stack is fullc. Check if the stack is halfway fulld. Check if the element is greater than the top element
