The matrix A=[-4 2 1;2 -4 1;1 2 -4] can be created by using the following code in Matlab/Octave:

A = -4*eye(3) + 2*(eye(3,3) - eye(3)) + (eye(3,3) - 2*eye(3))

Here, eye(3) creates an identity matrix of size 3x3 with ones on the diagonal and zeros elsewhere.

eye(3,3) - eye(3) creates a matrix of size 3x3 with ones on the off-diagonal and zeros on the diagonal.

eye(3,3) - 2*eye(3) creates a matrix of size 3x3 with -1 on the off-diagonal and zeros on the diagonal.

The code above uses the properties of the identity matrix and the properties of matrix addition and scalar multiplication to create the desired matrix A.

You can also create the matrix A by using following code:

A = [-4 2 1; 2 -4 1; 1 2 -4]

It is not necessary to create the matrix A using only ones and zeroes but this is one of the way to create this matrix.

Answer:

Explanation:

a) In random Pivot Quick Sort algorithm, a Central Pivot element is chosen. In this algorithm Pivot element is selected as it is not Central Pivot. It means the array is divided such that any part contains at-least ¼ elements.

Algorithm for Quick Sort using Random Pivot

randomQuick(num[ ],low,high)

Step 1 – if low index > = high index then Exit.

Step 2 – while pivot p is not the Central Pivot.

Step 3 – Choose any value randomly as the Pivot value. Assume it as p.

Step 4 – Count the elements smaller than num[p]. Store it as small.

Step 5 – Count the elements greater than num[p]. Store it as great.

Step 6 – Assume size = (high – low + 1) . if small > = size/4 and greater >=n/4, then p is Central Pivot.

Step 7 – Use pivot p to partition num [low…high].

Step 8 – randomQuick(num, low, small - 1)

Step 9 – randomQuick(num, great + 1, high)

b) As from the above algorithm the array is partitioned in such two parts that one part has at-least n/4 elements. Thus, it is possible that in worst case, array is partitioned in two parts such that one part has n/4 elements and other part has 3n/4 elements and its time complexity will be O(log N).

Whereas there is a loop in the above algorithm. So, complexity is O(n)

Now consider the following recurrence relation:

T(n) = T(n/4) + T(3n/4) + O(n)

       = O(log n) + O(n)

       = O(n log n).

c) In QuickSort as randomly Pivot is generated. Here, in the above algorithm one condition follows the array is divided in such two partitions that one part has n/4 elements and the other part has 3n/4 elements.

In worst case, the height of recursion tree is Log3/4 n.

Answer:

The initial amount invested by Olivia is $ 27,683.79  

Explanation:

The amount of initial investment can be computed using the present value formula given below:

PV=FV*(1+rs/t)^-n*t

FV is the future amount which is $50,000

rs is the rate of interest which is 12%  per annum

t is the number of times interest is compounded yearly which is 4 times

n is the number of years the funds were invested i.e 5 years

PV=$50,000*(1+12%/4)^-4*5

PV=$50,000*(1+3%)^-20=$27,683.79  

The vapor pressure of a liquid decreases as the strength of the attractive intermolecular forces increases.

The vapor pressure of a liquid is the point, in a closed container, at which equilibrium pressure is reached between molecules leaving the liquid and entering the gas phase and molecules leaving the gas phase and entering the liquid phase.

The vapor pressure of liquids can be measured in a number of ways. A simple measurement is to inject liquid into a closed flask connected to a pressure gauge. Click here for illustrations. When a solid or liquid evaporates into a gas in a closed container, molecules cannot escape.

Vapor pressure (or equilibrium vapor pressure) is the pressure exerted by a vapor in thermodynamic equilibrium with a condensed phase (solid or liquid) at a given temperature in a closed system.

The question says :

You are working on a documentation file userNotes.txt with some members of your software development team. Just before the file needs to be submitted, you manager tells you that a company standard requires that one blank space be left between the end-of-sentence period (.) and the start of the next sentence. (This rule does not affect sentences at the very end of a line.) For example, this is OK: Turn the knob. Push the "on" button. This is not: Turn the knob. Push the "on" button. Asking around among your team members, you discover that some of them have already typed their sentences in the approved manner, but others have inserted two or even more blanks between sentences. You need to fix this fast, and the first thing you want to do is to find out how bad the problem is. What command would you give to list all lines of userNotes.txt that contain sentence endings with two or more blanks before the start of the next sentence?

Solution:

Here, our fundamental aim is to look for the content which is having single space between different sentences. As it sentences finishing with . Going before with single and various spaces we have to channel and match just e the sentences which are finishing with ". "

For this we use order called "GREP" in Unix. "GREP " represents worldwide quest for standard articulation. This order is utilized inquiry and print the lines that are coordinating with determined string or an example. The example or indicated string that we have to look through we call it as customary articulation.

Syntax of GREP:

Answer:

I am writing a Python program:

This is the find_max_sales

def find_max_sales(tuple_list): #method that takes a list of tuples as parameter and returns the movie name which had the most sales

   maximum=0  #stores the maximum of the ticket sales

   name=""  #stores the name of the movie with maximum sales

   for tuple in tuple_list:  # iterates through each tuple of the tuple list

       [movie, sale]= tuple  #tuple has two items i.e. movie contains name of the movies and sale holds the total ticket sale of the movie

       if sale>maximum:  #if the sale value of a tuple is greater than that of maximum sale value

           maximum=sale  #assigns the maximum of sales to maximum variable

           name=movie  # assigns the movie name which had most sales to name variable

   return name #returns the movie name that had the most sales and not the full tuple

#Below is the list of list of movies. This list is passed to the find_max_sales method which returns the movies name from the list that had the most sales.

movie_list = [("Finding Dory", 486), ("Captain America: Civil War", 408), ("Deadpool", 363), ("Zootopia", 341), ("Rogue One", 529), ("The Secret Life of Pets", 368), ("Batman v Superman", 330), ("Sing", 268), ("Squad", 325), ("The Jungle Book", 364)]

print(find_max_sales(movie_list))

Explanation:

The program has a method find_max_sales that has one parameter tuple_list which is a list of tuples. Each tuple i.e. tuple has two items a movie which is a string and sale which is an integer. The movie represents the name of a movie, and the sales represents that movie's total ticket sales  The function has a loop that iterates through each tuple tuple of the list tuple_list. Variable maximum holds the value of the maximum sales. The if condition checks if the value of tuple sale is greater than that stored in maximum, at each iteration. If the condition evaluates to true then that sale tuple value is assigned to maximum variable so that the maximum holds the maximum of the ticket sales. The name variable holds the name of the movie corresponding to the maximum sale tuple value. The method returns the movie name from the tuple_list that has the most sales.

For example in the above given movie_list , the maximum of sale is of the movie Rogue One. When the method is called it returns the movie name and not the full tuple so the output of the above program is:

Rogue One
