Determine, for a given graph G =V,E and a positive integer m ≤ |V |, whether G contains a clique of size m or more. (A clique of size k in a graph is its complete subgraph of k vertices.)

Determine, for a given graph G = V,E and a positive integer m ≤ |V |, whether there is a vertex cover of size m or less for G. (A vertex cover of size k for a graph G = V,E is a subset V⊆ V such that |V| = k and, for each edge (u, v) ∈ E, at least one of u and v belongs to V.)

a.)Describe the process of showing that a problem is NP complete

b.) given that the CLIQUE problem is NP complete. show that the VERTEX COVER problem is NP complete.

2. Let U = {r, s, t, u, v, w, x, y, z}, D = {s, t, u, v, w}, E = {v, w, x}, and F = {t, u}. Use roster notation to list the elements of D ꓴ E.

3. Let U = {r, s, t, u, v, w, x, y, z}, D = {s, t, u, v, w}, E = {v, w, x}, and F = {t, u}. Use roster notation to list the elements of E ∩ F.

Learn to debug code

Problem: Sorting Book Objects

Download the provided zipped folder from Canvas. The source java files and test cases are in

the provided

folder. The Book class models a book. A Book has a unique id, title, and author.

The BookStore class stores book objects in a List, internally stored as an ArrayList. Also, the

following methods are implemented for the BookStore class.

•

addBook(Book b):

sto

res the book in the book list.

•

getBookSortedByAuthor():

returns a book list sorted by author name descending

alphabetically.

•

getBooksSortedByTitle():

returns a book listed sorted by title descending alphabetically.

•

getBooks():

returns the current book list

.

•

deleteBook(Book b5):

removes the given book from the book list.

•

countBookWithTitle(String title):

iterates through the book list counting the number of

books with the given title. Returns the count of books with the same title.

Write test cases to test t

he implementation.

The test case method stubs have been created.

Fill out the method stubs. After filling in the test case method stubs, run BookStoreTest to test

the BookStore.java code. Find and fix bugs in the BookStore.java code by using the debugger o

n

the test case method stubs.

Roger is conducting a biochemical experiment for the next 12

months. In the first month, the expenses are estimated to be

$10,000. As the experiment progresses, the expenses are expected

to increase by

2 percent each month. Roger plans to pay for the

experiment with a government

grant, which is received in four

monthly installments, starting a month after the experiment

completion date. Draw the cash flow diagram for this experiment.

Determine the amount of the monthly installment so that the

installments received are equal in value to the expenses incurred.

Annual nominal interest is 1

0 percent, compounded monthly.
