Following are the solution to the given question:
Explanation:
In this order, it is typically the GPU and CPU. The most important way to consider is to look at the details of the components to enhance watts. Add up to 100 watts so make sure it was safe and ok. Just buy a PSU with an extra 100 watts of leeway for your system. This is indeed a slight price difference.
Given two regular expressions r1 and r2, construct a decision procedure to determine whether the language of r1 is contained in the language r2; that is, the language of r1 is a subset of the language of r2.
Answer:
Test if L(M1-2) is empty.
Construct FA M2-1 from M1 and M2 which recognizes the language L(>M2) - L(>M1).
COMMENT: note we use the algorithm that is instrumental in proving that regular languages are closed with respect to the set difference operator.
Test if L(M2-1) is empty.
Answer yes if and only if both answers were yes.
Explanation:
An algorithm must be guaranteed to halt after a finite number of steps.
Each step of the algorithm must be well specified (deterministic rather than non-deterministic).
Three basic problems:
Given an FA M and an input x, does M accept x?
Is x in L(M)
Given an FA M, is there a string that it accepts?
Is L(M) the empty set?
Given an FA M, is L(M) finite?
Algorithm for determining if M accepts x.
Simply execute M on x.
Output yes if we end up at an accepting state.
This algorithm clearly halts after a finite number of steps, and it is well specified.
This algorithm is also clearly correct.
Testing if L(M) is empty.
Incorrect "Algorithm"
Simulate M on all strings x.
Output yes if and only if all strings are rejected.
The "algorithm" is well specified, and it is also clearly correct.
However, this is not an algorithm because there are an infinite number of strings to simulate M on, and thus it is not guaranteed to halt in a finite amount of time.
COMMENT: Note we use the algorithm for the first problem as a subroutine; you must think in this fashion to solve the problems we will ask.
Correct Algorithm
Simulate M on all strings of length between 0 and n-1 where M has n states.
Output no if and only if all strings are rejected.
Otherwise output yes.
This algorithm clearly halts after a finite number of steps, and it is well specified.
The correctness of the algorithm follows from the fact that if M accepts any strings, it must accept one of length at most n-1.
Suppose this is not true; that is, L(M) is not empty but the shortest string accepted by M has a length of at least n.
Let x be the shortest string accepted by M where |x| > n-1.
Using the Pumping Lemma, we know that there must be a "loop" in x which can be pumped 0 times to create a shorter string in L.
This is a contradiction and the result follows.
COMMENT: There are more efficient algorithms, but we won't get into that.
Testing if L(M) is finite
Incorrect "Algorithm"
Simulate M on all strings x.
Output yes if and only if there are a finite number of yes answers.
This "algorithm" is well specified and correct.
However, this is not an algorithm because there are an infinite number of strings to simulate M on, and thus it is not guaranteed to halt in a finite amount of time.
COMMENT: Note we again use the algorithm for the first problem as a subroutine.
Correct Algorithm
Simulate M on all strings of length between n and 2n-1 where M has n states.
Output yes if and only if no string is accepted.
Otherwise output no.
This algorithm clearly halts after a finite number of steps, and it is well specified.
The correctness of the algorithm follows from the fact that if M accepts an infinite number of strings, it must accept one of length between n and 2n-1.
This builds on the idea that if M accepts an infinite number of strings, there must be a "loop" that can be pumped.
This loop must have length at most n.
When we pump it 0 times, we have a string of length less than n.
When we pump it once, we increase the length of the string by at most n so we cannot exceed 2n-1. The problem is we might not exceed n-1 yet.
The key is we can keep pumping it and at some point, its length must exceed n-1, and in the step it does, it cannot jump past 2n-1 since the size of the loop is at most n.
This proof is not totally correct, but it captures the key idea.
COMMENT: There again are more efficient algorithms, but we won't get into that.
Other problems we can solve using these basic algorithms (and other algorithms we've seen earlier this chapter) as subroutines.
COMMENT: many of these algorithms depend on your understanding of basic set operations such as set complement, set difference, set union, etc.
Given a regular expression r, is Lr finite?
Convert r to an equivalent FA M.
COMMENT: note we use the two algorithms for converting a regular expression to an NFA and then an NFA to an FA.
Test if L(M) is finite.
Output the answer to the above test.
Given two FAs M1 and M2, is L(M1) = L(M2)?
Construct FA M1-2 from M1 and M2 which recognizes the language L(>M1) - L(>M2).
COMMENT: note we use the algorithm that is instrumental in proving that regular languages are closed with respect to the set difference operator.
Test if L(M1-2) is empty.
Construct FA M2-1 from M1 and M2 which recognizes the language L(>M2) - L(>M1).
COMMENT: note we use the algorithm that is instrumental in proving that regular languages are closed with respect to the set difference operator.
Test if L(M2-1) is empty.
Answer yes if and only if both answers were yes.
While saving a document to her hard drive, Connie's computer screen suddenly changed to display an error message on a blue background. The error code indicated that there was a problem with her computer's RAM. Connie's computer is affected by a(n) __________.
Answer:
The right answer is "Hardware crash".
Explanation:
According to the runtime error message, this same RAM on your machine was problematic. This excludes file interoperability or compliance problems as well as program error possibilities.Assuming implementation performance problems exist, the timeframe that would save the information would be typically longer, but there's still a lower possibility that the adequacy and effectiveness color will become blue but instead demonstrate warning would appear.Thus the above is the right solution.

Write a program that first reads in the name of an input file and then reads the input file using the file.readlines() method. The input file contains an unsorted list of number of seasons followed by the corresponding TV show. Your program should put the contents of the input file into a dictionary where the number of seasons are the keys, and a list of TV shows are the values (since multiple shows could have the same number of seasons).
Sort the dictionary by key (least to greatest) and output the results to a file named output_keys.txt, separating multiple TV shows associated with the same key with a semicolon (;). Next, sort the dictionary by values (alphabetical order), and output the results to a file named output_titles.txt.
Ex: If the input is:
file1.txt
and the contents of file1.txt are:
20
Gunsmoke
30
The Simpsons
10
Will & Grace
14
Dallas
20
Law & Order
12
Murder, She Wrote
the file output_keys.txt should contain:
10: Will & Grace
12: Murder, She Wrote
14: Dallas
20: Gunsmoke; Law & Order
30: The Simpsons
and the file output_titles.txt should contain:
Dallas
Gunsmoke
Law & Order
Murder, She Wrote
The Simpsons
Will & Grace
Note: There is a newline at the end of each output file, and file1.txt is available to download.
currently, my code is:
def readFile(filename):
dict = {}
with open(filename, 'r') as infile:
lines = infile.readlines()
for index in range(0, len(lines) - 1, 2):
if lines[index].strip()=='':continue
count = int(lines[index].strip())
name = lines[index + 1].strip()
if count in dict.keys():
name_list = dict.get(count)
name_list.append(name)
name_list.sort()
else:
dict[count] = [name]
return dict
def output_keys(dict, filename):
with open(filename,'w+') as outfile:
for key in sorted(dict.keys()):
outfile.write('{}: {}\n'.format(key,';'.join(dict.get(key))))
print('{}: {}\n'.format(key,';'.join(dict.get(key))))
def output_titles(dict, filename):
titles = []
for title in dict.values():
titles.extend(title)
with open(filename,'w+') as outfile:
for title in sorted(titles):
outfile.write('{}\n'.format(title))

Christina has been asked by the firewall administration group to identify secure network protocols that can be used to prevent network analyzers from being able to read data in flight. What are considered as secure network protocols?
Answer:
SSH, HTTPS and SMTP
Explanation:
Data theft can be defined as a cyber attack which typically involves an unauthorized access to a user's data with the sole intention to use for fraudulent purposes or illegal operations. There are several methods used by cyber criminals or hackers to obtain user data and these includes DDOS attack, SQL injection, man in the middle, phishing, etc.
Encryption is a form of cryptography and typically involves the process of converting or encoding informations in plaintext into a code, known as a ciphertext. Once, an information or data has been encrypted it can only be accessed and deciphered by an authorized user.
Some examples of encryption algorithms are 3DES, AES, RC4, RC5, and RSA.
Hence, SSH, HTTPS and SMTP are considered as secure network protocols.
HTTPS is acronym for Hypertext Transfer Protocol Secure while SSL is acronym for Secure Sockets Layer (SSL).
SMTP is an acronym for Simple Mail Transfer Protocol and it uses the standard port number of 25 to provide clients with requested services.
Write a function called rotateRight that takes a String as its first argument and a positive int as its second argument and rotates the String right by the given number of characters. Any characters that get moved off the right side of the string should wrap around to the left.
Answer:
The function in Python is as follows:
def rotateRight(strng, d):
lent = len(strng)
retString = strng[lent - d : ] + strng[0 : lent - d]
return retString
Explanation:
This defines the function
def rotateRight(strng, d):
This calculates the length of the string
lent = len(strng)
This calculates the return string
retString = strng[lent - d : ] + strng[0 : lent - d]
This returns the return string
return retString
Addition:
The return string is calculated as thus:
This string is split from the index passed to the function to the last element of the string, i.e. from dth to last.
The split string is then concatenated to the beginning of the remaining string
Read integers from input and store each integer into a vector until -1 is read. Do not store -1 into the vector. Then, output all values in the vector (except the last value) with the last value in the vector subtracted from each value. Output each value on a new line. Ex: If the input is -46 66 76 9 -1, the output is:
-55
57
67
Answer:
The program in C++ is as follows:
#include <iostream>
#include <vector>
using namespace std;
int main(){
vector<int> nums;
int num;
cin>>num;
while(num != -1){
nums.push_back(num);
cin>>num; }
for (auto i = nums.begin(); i != nums.end(); ++i){
cout << *i <<endl; }
return 0;
}
Explanation:
This declares the vector
vector<int> nums;
This declares an integer variable for each input
int num;
This gets the first input
cin>>num;
This loop is repeated until user enters -1
while(num != -1){
Saves user input into the vector
nums.push_back(num);
Get another input from the user
cin>>num; }
The following iteration print the vector elements
for (auto i = nums.begin(); i != nums.end(); ++i){
cout << *i <<endl; }

the grade point average collected from a random sample of 150 students. assume that the population standard deviation is 0.78. find the margin of error if c = 0.98.
Answer:
[tex]E = 14.81\%[/tex]
Explanation:
Given
[tex]n = 150[/tex]
[tex]\sigma = 0.78[/tex]
[tex]c = 0.98[/tex]
Required
The margin of error (E)
This is calculated as:
[tex]E = z * \frac{\sigma}{\sqrt{n}}[/tex]
When confidence level = 0.98 i.e. 98%
The z score is: 2.326
So, we have:
[tex]E = 2.326 * \frac{0.78}{\sqrt{150}}[/tex]
[tex]E = 2.326 * \frac{0.78}{12.247}[/tex]
[tex]E = \frac{2.326 *0.78}{12.247}[/tex]
[tex]E = \frac{1.81428}{12.247}[/tex]
[tex]E = 0.1481[/tex]
Express as percentage
[tex]E = 14.81\%[/tex]

In a paragraph, describe in detail a practical real-world example of where you would implement a singly-linked list and why a singly-linked list is best for this use. Do not list the properties of a singly-linked list....
Rather identify a real-world example or application. If you identify this through research, cite your source.
Answer:
travel
Explanation:
One real world example of a singly-linked list would be travel. Imagine that you want to take a trip to your nearest neighbor state. To do so you would need to take a 2 buses and a train, but you can't just take any or in any order you wish. You first need to take the first bus at your current location, get off at the train station, take that train to the final stop, get off and take the bus to the final destination. Meaning there is a sequence of connected events that you must follow in order to get to your destination and the same opposite sequence of events to get back. This is exactly like a singly-linked list.

The input to the function/method consists of two arguments.
a. True
b. False
Answer:
See Explanation
Explanation:
The function is not given. So, I will provide general explanation.
A function is defined as:
return-type function-name(argument-lists)
For instance, an int function that has 1 argument is:
int Myfunc(int num)
num is the argument of the function Myfunc
So, an example of a function with two arguments is:
int Myfunc(int num, string name)
So, examine the function in the complete question; then count the number of arguments to determine if the answer is true or false.

what is the meaning of antimonographycationalis
Answer:
Although this word was made up in order to be a contender for the longest word in English, it can be broken down into smaller chunks in order to understand it.
Anti- means that you are against something; monopoly means the exclusive control over something; geographic is related to geography; and the remaining part has to do with nationalism.
So this word means something like 'a nationalistic feeling of being against geographic monopoly,' but you can see that it doesn't have much sense.
