Answer:

- Iterate over the Bellman-Ford algorithm n-1 time while tracking the parent vertex and store in an array.

- Do another iteration and if no relaxation of the edges occurs in the nth iteration then print of return "There are no negative cycle".

- Else, store the vertex of the relaxed edge at the nth iteration with a variable name.

- Then iterate over the vertexes starting from the store vertex until a cycle is found then print it out as the cycle of negative weight.

Explanation:

The Bellman-Ford algorithm can be used to detect a negative cycle in a graph. The program should iterate over the algorithm, in search of a relaxed edge. If any, the vertex of the specified edge is used as a starting point to get the target negative cycle.

Answer:

The Unix core used in Apple's macOS is called Darwin which is similar to the BSD Unix operating system. The Darwin in macOS has evolved, providing a slick aqua-graphical user interface for users to interact with the application by clicking rather than writing Unix commands in terminals.

Explanation:

The macOS is the operating system used by Apple computer brands. The operating system is a subset of the Unix's BSD operating system. It still makes use of the traditional Unix terminal and scripts but with a few alterations.

The significance of the UNIX core of macOS can be briefly described as:

This refers to the different kernel subsystems which are a part of the process management and memory allocation of a device.

Hence, the significance of the UNIX core of macOS has made it very easy for Apple users to communicate with their device in real time and also to power the phone.

Explanation:

Pointers in C are variables used to point to the location of another variable. To declare pointer, the data type must be specified (same as the variable it is pointing to), followed by an asterisk and then the name of the pointer. The reference of the target variable is also assigned to the pointer to allow direct changes from the pointer variable.

The program is written on 9 lines and the line by line explanation is as follows:

Line 1:

This defines the function

Line 2:

This begins a try except exception that returns an exception if an error is encountered

Line 3:

This open the source file using open and with statement

Line 4:

This open the destination file using open and with statement and also makes it writable

Line 5:

This iterates through the content of the source file; line by line

Line 6:

This writes the content to the destination file

Line 7 & 8:

This is returned if an error is encountered

Line 9:

This prints that the file has been successfully copied        

To call the function from main; use

copy(filename1, filename2)

Where filename1 and filename2 are names of source and destination files.

Take for instance:

filename1 = "test1.txt"

filename1 = "test2.txt"

copy(filename1, filename2)

The above will copy from test1.txt to test2.txt

The function copies text from one file to another. The program written in python 3 goes thus

def copy(filename1, filename2):

#initialize a function names copy and takes two arguments which are two files

try:

#initiate exception to prevent program throwing an error

with open(filename1, "r") as file1 :

#open file1 in the read mode with an alias

with open(filename2, "w") as file2:

#open file 2 in write mode with an alias

for line in file1:

#loop through each line in file 1

file2.write(line)

#copy / write the line in file2

except:

print("Error copying file")

#display if an error is encountered

print("File Copied")

#if no error, display file copied

import numpy as np

word = input("Enter a word: ")

acc = []

with open("Downloads/record-collection.txt", "r") as file:

   lines = file.readlines()

   for line in lines:

       if word in line:

           line = line.strip()

           acc.append(int(line[0]))

   if np.mean(acc) >= 2:

       print(f"The word {word} is a positive word")

       print(f"{word} appeared {len(acc)} times")

       print(f"the review of the word {word} is {round(np.mean(acc), 2)}")

   else:

       print(f"the word {word} is a negative word with review\

{round(np.mean(acc), 2)}")

Explanation:

The python program gets the text from the review file, using the user input word to get the definition of reviews based on the word, whether positive or negative.

The program uses the 'with' keyword to open the file and created the acc variable to hold the reviews gotten. The mean of the acc is calculated with the numpy mean method and if the mean is equal to or greater than 2 it is a positive word, else negative.

Answer:

1) 40%

Explanation:

Given the data size = 60 byte

data traversed through TSP then IP

Header size of TCP = 20 bytes to 60 bytes

Header size of IP = 20 bytes to 60 bytes

Calculating overhead:

By default minimum header size is taken into consideration hence TCP header size = 20 bytes and IP header size = 20 bytes

Hence, the correct answer is option 1 = 40%

Answer:

create a 2-dimensional array, let both rows represent the strings X and Y.

check for the common characters within a string and compare them with the other string value.

If there is a match, append it to the array rows.

After iterating over both strings for the substring, get the longest common substring for both strings and print.

Explanation:

The algorithm should create an array that holds the substrings, then use the max function to get the largest or longest substring in the array.

D. It allowed SOHO sites to appear as a single IP address, (and single device), to the Internet even though there may be many devices that use IP addresses on the LAN at the SOHO site.

Explanation:

Network Address Translation (NAT) gives a router the ability to translate a public IP address to a private IP address and vice versa.  With the added security that it provides to the network, it keeps the private IP addresses hidden (private) from the outside world.  By so doing, NAT permits routers (single devices) to act as agents between the Internet (public networks) and local (private) networks.  With this facilitation, a single unique IP address is required to represent an entire group of computers to anything outside their networks.

  int i = 2;

  double j = 3;

  int *p = &i;

  cout << "p = " << p << ", p+1 = " << p+1 << endl;

  cout << "q = " << q << ", q+1 = " << q+1 << endl;

  return 0;

}

Explanation:

In C++, pointers are variables or data types that hold the location of another variable in memory. It is denoted by asterisks in between the data type and pointer name during declaration.

The C++ source code above defines two pointers, "p" which is an integer pointer and "q", a double. The reference of the variables i and j are assigned to p and q respectively and the out of the pointers are the location of the i and j values in memory.

Answer:

SELECT customer_last_name, customer_city, customer_zip FROM customers WHERE customer_state = 'IL' ORDER BY customer_last_name DESC;

Explanation:

Here, we are given a SCHEMA with the table name customers.

It's creation command and commands to insert values are also given.

We have to print the customer last name, city and zip code of all the customers who have their state as IL in the decreasing order of their last names.

Let us learn a few concepts first.

1. To print only a specified number of columns:

We can write the column names to be printed after the SELECT command.

2. To print results as per a condition:

We can use WHERE clause for this purpose.

3. To print in descending order:

We can use ORDER BY clause with the option DESC to fulfill the purpose.

Therefore, the answer to our problem is:

SELECT customer_last_name, customer_city, customer_zip FROM customers WHERE customer_state = 'IL' ORDER BY customer_last_name DESC;

Output of the command is also attached as screenshot in the answer area.

Answer:

Following are the program to this question:

def sum_of_squares(no_more_than):#defining a method sum_of_squares that accepts a variable

   i = 1#defining integer variable  

   t = 0#defining integer variable

   while(t+i**2 <= no_more_than):#defining a while loop that checks t+i square value less than equal to parameter value  

       t= t+ i**2#use t variable to add value

       i += 1#increment the value of i by 1

   return t#return t variable value

print(sum_of_squares(12))#defining print method to call sum_of_squares method and print its return value

Output:

5

Explanation:

In the program code, a method "sum_of_squares" is declared, which accepts an integer variable "no_more_than" in its parameter, inside the method, two integer variable "i and t" are declared, in which "i" hold a value 1, and "t" hold a value that is 0.

In the next step, a while loop has defined, that square and add integer value and check its value less than equal to the parameter value, in the loop it checks the value and returns t variable value.
