Which of the following methods inserts an element into a stack data structure? A. enqueue B. dequeue C. push D. pop E. peek

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.

Which of the following data structures allows to insert elements from one end and remove them from the same end?Group of answer choicesBoth Deque and StackDequeCircular QueueStack

Match the following stack operations with their respective array-based counterparts:A. PushB. PopC. Peek (or Top)i. Adding an element to the stackii. Removing an element from the top of the stackiii. Examining the top element without removing ita)A - ii, B - i , C - iiib)A - iii, B - ii, C - ic)A - ii, B - ii, C - iiid)A - i, B - ii, C - iii

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

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
