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 input Mary had a little lamb. Its fleece was white as snow. into Lamb little a had mary. Snow as white was fleece its. Pay attention to capitalization and the placement of the period.

This is what I have so far: import java.util.Scanner;import java.util.Stack; /** Class for reversing the order of a sentence.*/public class SentenceReverser{ /** Reverses the given sentence. @param sentence Sentence to be reversed. @return Reversed sentence. */ public static String reverse(String sentence) { String reversed = ""; Scanner scanner = new Scanner(sentence); Stack<String> stack = new Stack<String>(); // put your work below // ... return…
The school cafeteria offers circular and square sandwiches at lunch break, referred to by numbers 0 and 1 respectively. All students stand in a queue. Each student either prefers square or circular sandwiches. The number of sandwiches in the cafeteria is equal to the number of students. You are given two integer arrays students and sandwiches where sandwiches[i] is the type of the ith sandwich in the stack (i = 0 is the top of the stack) and students[j] is the preference of the jth student in the initial queue (j = 0 is the front of the queue). Part 1: Modify the code given and make it more efficient. You can try to implement your own stack or your own Queue. Or you can use the sandwiches array as a stack without making a separate Stack class. Same with the students array. Part 2: After modifying the code, explain how it works, and why it is more efficient than the solution that you started with. (Or, if it turns out that the change you made is not more efficient, try to…

Create a stack S of ten elements. Take a number x from the user and delete the elements smaller than or equal to X from the stack. Example: Suppose your initial stack is S where you pushed 10 elements as below- Top {9, 3, 4, 15, 20, 1, 6, 4, 9, 10} Bottom X is taken as input and X= 6. Then pop out and remove the elements greater than or equal to X. Finally, the stack will look like- Top {3, 4, 1, 4} Bottom In c++ Please
For our first example of using a stack, we’ll examine a very simple task: reversing aword. When you run the program, it asks you to type in a word. When you press Enter, itdisplays the word with the letters in reverse order.A stack is used to reverse the letters. First the characters are extracted one by one fromthe input string and pushed onto the stack. Then they’re popped off the stack and displayed. Because of its last-in-first-out characteristic, the stack reverses the order of thecharacters. shows the code for the reverse.cpp program.
I am trying to 1) double a number that is given by a user. 2) Take that number and divided it by 10 until it no longer is divisable by 10. 3)Push each individual modula onto a stack so that the doubled number saves into the Stack from right to left. eg.(User enters 123...console should double the value to 246, and then place 6**4**2** into a stack. 6 being the topmost number) The roadblock I am getting to is that when I try to push the numbers on the stack with a while loop, it seems like push only remembers the last number that was pushed.
You have a stack of n boxes, with widths w1, heights hi, and depths di. The boxescannot be rotated and can only be stacked on top of one another if each box in the stack is strictlylarger than the box above it in width, height, and depth. Implement a method to compute theheight of the tallest possible stack. The height of a stack is the sum of the heights of each box.
Write a function that takes a string of words as an input, uses a stack to reverse the words and returns the reversed stringFor instance, if the user were to input “stacks are fun”, the function wouldreturn “fun are stacks”. Make sure you call the function to test it
java /* Practice Stacks and ourVector Write a java program that creates a stack of integers. Fill the stack with 30 random numbers between -300 and +300. A)- With the help of one ourVector Object and an additional stack, reorganize the numbers in the stack so that numbers smaller than -100 go to the bottom of the stack, numbers between -100 and +100 in the middle and numbers larger than +100 in the top (order does not matter) B)- (a little harder) Solve the same problem using only one ourVector object for help C)- (harder) Solve the same problem using only one additional stack as a helper */ public class HWStacks { public static void main(String[] args) { // TODO Auto-generated method stub } }
The following piece of code incorrectly attempts to remove all even values from a stack of integers. What is wrong with the code, and how would you fix it? while (!s.isEmpty()) { int n = s.pop(); if (n % 2 != 0) { s.push(n); // put back in stack if odd } }
Write a program to sort a stack such that the smallest items are on the top. You can usean additional temporary stack, but you may not copy the elements into any other data structure(such as an array). The stack supports the following operations: push, pop, peek, and is Empty
Let a stack of N=5 elements be denoted as: S={3,7,9,2,_}What would the stack look like after the following operations?pop( )pop( )push(11)push(3)pop( )pop( )pop( ) Select one: a.S={3,7,3,11,_} b.S={3,7,11,3,_} c.S={3,_,_,_,_} d.S={11,_,_,_,_} e.S={3,7,11,_,_}
