Problem Statement
4
This problem has you modify a linked lists composed of node objects
chained together via node pointers. Each node has a next pointer which
points to the next node in the chain. The last node is identified by having
a NULL next pointer.
The linked lists for this lab store string data. Some of the strings in the
linked lists repeat, and we'd like to eliminate this repetition. Specifically, if
a string repeats, we want to eliminate the duplicates so that the resulting
linked list only has one copy of a string in a row. (The string can repeat
later in the linked list, as long as some other string occurs in between.)
Create a function compress, which takes in a pointer to the head of the
linked list, and returns a pointer to the head of a linked list in which
repetition has been eliminated
The linked list for this problem uses the following class declaration
class node
public:
string data;
node* next;
d:
Notes and Constraints
The linked list starting at head contains between 1 and 25 nodes,
inclusive

Prerequisites: Java, VS Code, and Terminal In this assignment you will develop and test a command-line application written in the Java language that asks questions to determine if a person is your true love. More specifically your application should ask five questions in the form of statements and allow the user to respond to each statement with the numbers 1 through 5 with 1 indicating strongly disagree and 5 indicating strongly agree. You will then compare the person’s answers with your desired “true love” answers. The closer the answers are to your desired “true love” answers the better match the two of you are for each other. For example, suppose you choose the statement “Broccoli is delicious.” and your desired answer was 1 (strongly disagree) because you really don’t like broccoli. If the application user entered 4 (agree), then the two of you would not…arrow_forward

An individual can put up to $5,500 per year tax free and the money grows tax free until the person is ready to retire. The tax rules related to IRA’s are complex, but for this assignment, we’ll assume that the person puts in the same amount of money every year (up to $5,500) and the money grows at a constant interest rate. Write a Flowgorithm program that asks the user to input an annual IRA contribution (in dollars), and interest rate (percent), and a time period (years). Calculate the value of the IRA every year for the duration of the time period provided by the user. Be sure and provide user friendly prompts. Include a comment at the beginning of the program with your name, date, and a short description of the program.arrow_forwardstructions: Write the following programs in C# using concepts learnt in this chapter and abmit the .cs file with the screenshot of your output for each question in the Lab Assignment 2 Submission page. 1.
