Stack:
Stacks are a type of container with LIFO (Last In First Out) type of working, where a new element is added at one end and (top) an element is removed from that end only. Your Stack should not be of the fixed sized. It should be able to grow itself. So using the class made in task 1, make a class named as Stack, having following additional functionalities:
bool empty() : Returns whether the Stack is empty or not. Time Complexity should be: O(1)
bool full() : Returns whether the Stack is full or not. Time Complexity should be: O(1)int size() : Returns the current size of the Stack. Time Complexity should be: O(1)Type top () : Returns the last element of the Stack. Time Complexity should be: O(1)
void push(Type) : Adds the element of type Type at the top of the stack. Time Complexity should be: O(1)
Type pop() : Deletes the top most element of the stack and returns it. Time Complexity should be: O(1)
Write non-parameterized constructor for the above class.
Write Copy…
10 - final question
If you create a new empty stack and push the values 1, 2, and 3 in
that order, and call pop on the stack once, Which value will be
returned?
