Explanation of Solution
Recursive method for removing all the elements in a stack:
An example code for a recursive method for removing all the elements in a stack is shown below.
//Import necessary header files
import java.util.*;
//Create a class
public class EmptyStack
{
//Define a method to empty the stack
public static Stack empty(Stack<Integer> st)
{
//Check whether stack is empty
if (st.isEmpty())
//Return the value
return st;
//Perform pop operation
st...

- I need some help with this problem. my instructions are "Write a recursive void method to display a single-ended singly linked list backwards. " i am using custom code for links and a linked list that comes from my textbook. the textbook is "Data Structures and Algorithms in Java Second Edition" by Robert Lafore in my code i made a method called recursiveReverse() which takes two arguments a integer count and an integer sizeOfList is supposed to use a for loop to get the method to where it needs to go on the list using a current and previous link. the current is where the method is at currently and the previous is where the current was before the list iterated. i am having trouble finding a way to get the method to end when the code finally gets to where it needs to be. the code before the first recursion should reach the end of the list and then count should be incremented in the recursion argument. the code presented is still not completely finished but please let me know if i am…arrow_forwardCan you please help me with this coding problem WITHOUT USING RECURSION?arrow_forwardDefine a recursive finction called arraySum to find sum of elements in a list.arrow_forward
