Stack:
It is a conceptual structure consisting of a set of homogenous elements and is based on the principle of last in first out. It has two major operations, first is the push and the other is the pop. The push operation adds the element to the stack and the pop operation removes the element from the stack. It is used in

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.
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…
Imagine a ballroom with two kinds of dancers: leaders and followers. Dancers of both kinds wait in two separate queues before entering the dance floor. When a leader arrives, it checks to see if there is a follower waiting. If so, they can both proceed. Otherwise it waits. Similarly, when a follower arrives, it checks for a leader and either proceeds or waits, accordingly. Make sure that the next pair of leader/follower may dance only after the previous pair is done.Write the pseudocode for leaders and followers that enforces these constraints.
Given a string, reverse it using a
stack. For example, the string "Hello!"
should be converted to "!olleH".

- It's a very nice application of stacks. Consider that a freight train has n railroad cars. Each to be left at different station. They're numbered 1 through n & freight train visits these stations in order n through 1. Obviously, the railroad cars are labeled by their destination. To facilitate removal of the cars from the train, we must rearrange them in ascending order of their number (i.e. 1 through n). When cars are in this order, they can be detached at each station. We rearrange cars at a shunting yard that has input track, output track & k holding tracks between input & output tracks (i.e. holding track). The figure shows a shunting yard with three holding tracks H1, H2 & H3, also n = 9. The n cars of freight train begin in the input track & are to end up in the output track in order 1 through n from right to left. The cars initially are in the order 5,8,1,7,4,2,9,6,3 from back to front. Later cars are rearranged in desired order. To rearrange cars, we…arrow_forwardThe puzzle includes various sizes of coins. It starts with an order of size, taking the top one the least. The puzzle needs to be constructed to have a conical shape and consider these laws: In every step, you can push one coin; every move includes taking the upper coin from the stack and putting it on top of other stack or starting a new stack. None of the coins can be put on top of the smaller coin; finally, at any moment, at most L, various stacks can be in use. Make PDDL in a way it will not rely on A and L.arrow_forwardUse stacks from the STL to implement a video game library functionality.

- Question Given a singly linked list, you need to do two tasks. Swap the first node with the last node. Then count the number of nodes and if the number of nodes is an odd number then delete the first node, otherwise delete the last node of the linked list. For example, if the given linked list is 1->2->3->4->5 then the linked list should be modified to 2->3->4->1. Because 1 and 5 will be swapped and 5 will be deleted as the number of nodes in this linked list is 5 which is an odd number, that means the first node which contains 5 has been deleted. If the input linked list is NULL, then it should remain NULL. If the input linked list has 1 node, then this node should be deleted and a new head should be returned. Sample 1: Input: NULL output: NULL. Sample 2: Input: 1 output: NULL Sample 3: Input: 1->2 output: 2 Sample 4: Input: 1->2->3 output: 2->1 Sample 5: Input: 1->2->3->4 _output: 4->2->3 Sample 6: Input: 1->2->3->4->5->6 output: 6->2->3->4->5.

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.arrow_forwardGiven a stack myData: Tom, Sam (top is Tom), what is the output after the following operations?

- Lab 18: Stack, SentenceReverser 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.

Thanks in advance.arrow_forwardWrite a program SentenceReverser that reverses the words in a sentence by reading words into a Stack until you find a period. Your program should then pop off the words from the stack. Begin your reverse sentence with a capital letter and end it with a period. Your program should be able to handle multiple sentences. Use while (scan.hasNext()) to capture your input. Mary had a little lamb. His fleece was as white as snow. Becomes: Lamb little a had mary. Snow as white as was fleece his. Note: Your test input should include multiple sentences as shown above. There should NOT be a space before your periods.arrow_forward
