What are stack operations in Data Structure?
A Stack in Data Structure is an abstract data type that acquires an ordered and linear sequence of elements. A stack is a First in Last out (FILO) data structure in which the item that is added first will be deleted last. In a stack, the elements are arranged in a sequence manner and thus they are called linear data structures. Stack operations in data structure like PUSH (insertion of an element) and POP (deletion of an element) are performed at the top of the stack.
