JAVA PROGRAM
Design a stack that supports push, pop, top, and retrieving the minimum element in constant time. • push(x) -- Push element x onto stack. • pop() -- Removes the element on top of the stack. • top() -- Get the top element. • getMin() -- Retrieve the minimum element in the stack. Example 1: Input ["MinStack", "push", "push","push", "getMin","pop","top", "getMin"] [1], [-2], [0], [-3],[1,1],[1, [1] Output [null, null, null,null,-3, null,0,-2] Explanation MinStack minStack = new MinStack(); minStack.push(-2); minStack.push(0);...
Stacks and queues 1. Show the status of the stack or return values along with the following sequence of operations. Push(5), push(3), size(), pop(), isEmptyO, pop(), isEmpty, pop, push(7), push(9), top(), push(4), size(), pop(), push(6), push(8), pop(). 2. What's the spatial cost of stack above? What's the temporal cost of push() and pop() operations, respectively?
Stacks There are two main operations associated with stacks; 1) putting things on the stack which is referred to as push, 2) taking things from the stack which is referred to as pop. We can create a stack using linked lists if we force ourselves to insert and remove nodes only at the top of the list. One use of a stack is when you want to write a word backward. In that case, you will read the letters of...
JAVA Lab Create a class called ArrayBasedStack. Declare the following variables: • data: references an array storing elements in the list • topOfStack: an int value representing the location of the stack top in the array • INITIAL_CAPACITY: the default capacity of the stack public class ArrayBasedStack <E> { private E[] data; private int topOfStack; private static final int INITIAL_CAPACITY = 5; } Add a constructor that will initialize the stack with a user-defined initial capacity. The top of the...

Consider these functions: push() : push an element into the stack pop() : pop the top-of-the-stack element top() : returns the item stored in top-of-the-stack-node What will be the output after performing these sequence of operations (after performing top()) push(20); push(4); pop(); push(10); push(6); pop(); pop(); push(5); top();
Java - data structures Suppose that in the array-based stack, the array doubles in size after multiple push operations. But later on, fewer than half of the array’s locations might actually be used by the stack due to pop operations. Revise the implementation so that its array also can shrink in size as objects are removed from the stack. Accomplishing this task will require two new private methods, as follows: The first new method checks whether we should reduce the...
Queues and Stacks Purpose: To review queues and stacks in Java, and to use the built-in Stack class and Queue interface. The Stack class is a generic class containing these methods: public void push(E value) - pushes a new value onto the Stack public E pop() - pops the next value off of the stack and returns it; throws EmptyStackExceptionl if stack is empty public E peek() - returns the next value on the Stack but does not pop it...
Create a Java Program that uses a Stack to implement a deck of cards. Import java.util.stack and use its classes and methods. Note that java.uitl.stack uses peek instead of top (as we did in class). Look up the documentation for java.uitl.stack to see what methods it contains and how to call them. Create a Stack of cards that will hold strings. Push new items to the stack (Use "Qclubs" for Queen of clubs and so on) After your 'deck' has...
