15 - final question When you call pop on a stack, the element is removed from the stack relative to the other elements. а. Тор b. Bottom
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…

Try a spatuladef pancake_scramble(text):Analogous to flipping a stack of pancakes by sticking a spatula inside the stack and flipping over the stack of pancakes resting on top of that spatula, a pancake flip of order k performed for the text string reverses the prefix of first k characters and keeps the rest of the string as it were. For example, the pancake flip of order 2 performed on the string 'ilkka' would produce the string 'likka'. The pancake flip of order 3 performed on the same string would produce 'klika'.A pancake scramble, as defined in the excellent Wolfram Challenges programming problems site, consists of the sequence of pancake flips of order 2, 3, ... , n performed in this exact sequence for the given n-character text string. For example, the pancake scramble done to the string 'ilkka' would step through the intermediate results 'likka', 'kilka', 'klika' and 'akilk'. This function should compute and return the pancake scramble of its parameter text string. text…

Your program must implements the linked list The program should have the following basic operations of list, which are: a) Add first, in between and last b) Delete first, in between and last c) Display all data The program should be an interactive program that allow user to choose type of operation.
