In a linked list-based stack, which operation retrieves the element at the top of the stack?*1 pointa. Peekb. Popc. Accessd. Remove

Which of the following is not part of the pop operation for a stack implemented using a linked list? A. adjust the top reference variable to point to the node pointed to by the next field of the node at the top of the stack B. declare a temporary reference variable and set it to point to the element at the top of the stack C. all of these are part of the pop operation for a stack implemented using a linked list D. determine if the stack is empty E. determine if the stack is full

In linked representation of stack the null pointer of the last node in the list signals ........a.Middle value of stackb.In between some valuec.Bottom of the stackd.Beginning of the stackClear my choice

3. True or False: In a linked list-based stack, the last element added is the first element to beremoved (LIFO), similar to an array-based stack.4. True or False: The primary advantage of implementing a stack using a linked list is theelimination of memory wastage associated with a fixed-size array.5. True or False: When implementing a stack using a linked list, a pop operation involvesdeleting the element at the end of the linked list, opposite to a push operation, whichinserts a new element at the beginning

In a linked implementation of a stack, a pushed element should be added to the end of the list. A. True B. False
