You are given N elements and your task is to Implement a Stack in which you ement in O(1) can get a minimum time. Answer Example 1: Input: push(2) push(3) pop() getMin() push(1) getMin() Output: 2 1 Explanation: In the first test case for query push(2) Insert 2 into the stack. The stack will be {2} push(3) Insert 3 into the stack. The stack will be {2 3} pop() Remove top element from stack Poped element will be 3 the stack will be {2} getMin() Return the minimum element min element will be 2 push(1) Insert 1 into the stack. The stack will be {2 1} getMin() Return the minimum element min element will be 1.

ADT stack lets you peek at its top entry without removing it. For some applications of stacks, youalso need to peek at the entry beneath the top entry without removing it. We will call such an operationpeekNxt. If the stack has more than one entry, peekNxt returns the second entry from the top without altering the stack. If the stack has fewer than two entries, peekNxt throws an exception. Write a linkedimplementation of a stack class call LinkedStack.java that includes a method peekNxt. Please make sure that this is included in peekNxt: If the stack has fewer than two entries, peekNxt throws an exception and if you could please make a main to execute peekNxt, thank you.There are 2 class, 1 with the peekNxt, and 1 for implementation. You only need to work on the first one with the peekNxt in it import java.util.EmptyStackException;import java.util.NoSuchElementException;public final class LinkedStack<T> implements StackInterface<T>{private Node topNode;…

Lab 18: Stack, SentenceReverser Java language Use a stack to reverse the words of a sentence. Keep reading words until you have a word that ends in a period, adding them onto a stack. When you have a word with a period, pop the words off and print them. Stop when there are no more words in the input. For example, you should turn the inputMary had a little lamb. Its fleece was white as snow.intoLamb little a had mary. Snow as white was fleece its.Pay attention to capitalization and the placement of the period.

The CopyTo method copies the contents of a stack into an array. The arraymust be of type Object since that is the data type of all stack objects. Themethod takes two arguments: an array and the starting array index to beginplacing stack elements. The elements are copied in LIFO order, as if they werepopped from the stack. write a short code fragment demonstrating a CopyTomethod call:
checkBalance Language/Type: Java Stack collections string Related Links: String Write a method named checkBalance that accepts a string of source code and uses a Stack to check whether the braces/parentheses are balanced. Every ( or { must be closed by a } or ) in the opposite order. Return the index at which an imbalance occurs, or -1 if the string is balanced. If any ( or { are never closed, return the string's length. Here are some example calls: // index 0123456789012345678901234567890 checkBalance("if (a(4) > 9) { foo(a(2)); }") returns -1 because balanced checkBalance("for (i=0;i<a(3};i++) { foo{); )") // returns 14 because } out of order checkBalance("while (true) foo(); }{ ()") returns 20 because } doesn't match any { checkBalance("if (x) {") returns 8 because { is never closed // // // Constraints: Use a single stack as auxiliary storage.
If you enqueue five elements into an empty queue and push the same elements in exactly the same order onto a stack, the elements on the queue from front to rear look the same as those on the stack from top to bottom. True False
If the elements “A”, “B”, “C” and “D” are placed in a stack and are removed one at a time, in what order will they be removed?
