Q: Answer-A _______ operation may give access to the top without modifying the stack.

In computer science, a stack is an abstract data type that serves as a collection of elements, with two principal operations push, which adds an element to the collection, and pop, which removes the most recently added element that was not yet removed. The order in which elements come off a stack gives rise to its alternative name, LIFO for last in, first out. Additionally, a peek operation may give access to the top without modifying the stack.
