Implement the generator function scale(s, k), which yields elements of the given iterable s, scaled by k. As an extra challenge, try writing this function using a yield from statement!
def scale(s, k):
"""Yield elements of the iterable s scaled by a number k.
>>> s = scale([1, 5, 2], 5)
>>> type(s)
>>> list(s)
[5, 25, 10]
>>> m = scale(naturals(), 2)
>>> [next(m) for _ in range(5)]
[2, 4, 6, 8, 10]
"""
Answers
Answer:
The generator function using yield from:
def scale(s, k):
yield from map(lambda x: x * k, s)
Another way to implement generator function that works same as above using only yield:
def scale(s, k):
for i in s:
yield i * k
Explanation:
The complete program is:
def scale(s, k):
"""Yield elements of the iterable s scaled by a number k.
>>> s = scale([1, 5, 2], 5)
>>> type(s)
<class 'generator'>
>>> list(s)
[5, 25, 10]
>>> m = scale(naturals(), 2)
>>> [next(m) for _ in range(5)]
[2, 4, 6, 8, 10]
"""
yield from map(lambda x: x * k, s)
If you want to see the working of the above generator function scale() as per mentioned in the above comments, use the following statements :
s = scale([1, 5, 2], 5)
print(type(s))
#The above print statement outputs:
#<class 'generator'>
print(list(s))
#The above print statement outputs a list s with following items:
#[5, 25, 10]
The function def scale(s, k): is
def scale(s, k):
yield from map(lambda x: x * k, s)
This function takes two parameters i.e. s and k and this function yields elements of the given iterable s, scaled by k.
In this statement: yield from map(lambda x: x * k, s)
yield from is used which allows to refactor a generator in a simple way by splitting up generator into multiple generators.
The yield from is used inside the body of a generator function.
The lambda function is a function that has any number of arguments but can only have one expression. This expression is evaluated to an iterable from which an iterator will be extracted. This iterator yields and receives values to or from the caller of the generator. Here the expression is x: x * k and iterable is s. This expression multiplies each item to k.
map() method applies the defined function for each time in an iterable.
The generator function can also be defined as:
def scale(s, k):
for i in s:
yield i * k
For the above example
s = scale([1, 5, 2], 5)
def scale(s,k): works as follows:
s = [1, 5, 2]
k = 5
for loop iterates for each item i in iterable s and yields i*k
i*k multiplies each element i.e 1,5 and 2 to k=5 and returns a list
At first iteration, for example, i*k = 1 * 5 = 5, next iteration i*k = 5*5 = 25 and last iteration i*k = 2*5 = 10. So the output. So
s = scale([1, 5, 2], 5) In this statement now s contains 5, 25 and 10
print(list(s)) prints the values of s in a list as: [5, 25, 10] So output is:
[5, 25, 10]

Sample output for the given program with inputs: 63 115 Patient data (before): 0 in, 0 lbs Patient data (after): 63 in, 115 lbs 1 Your solution goes here ' 2 1 test passed 4 patient PatientData () 5 print('Patient data (before):, end-' ') 6 print(patient.height_inches, 'in,, end=' ') 7 print(patient.weight_pounds, lbs') All tests passed 9 10 patient.height_inches = int(input()) 11 patient.weight_pounds = int(input()) 12 13 print('Patient data (after):', end-' ') 14 print (patient. height_inches, 'in,', end- ') 15 print(patient.weight_pounds, 'lbs') Run
Answers
Answer:
class PatientData(): #declaration of PatientData class
height_inches=0 #attribute of class is declared and initialized to 0
weight_pounds=0 #attribute of class is declared and initialized to 0
Explanation:
Here is the complete program:
#below is the class PatientData() that has two attributes height_inches and weight_pounds and both are initialized to 0
class PatientData():
height_inches=0
weight_pounds=0
patient = PatientData() #patient object is created of class PatientData
#below are the print statements that will be displayed on output screen to show that patient data before
print('Patient data (before):', end=' ')
print(patient.height_inches, 'in,', end=' ')
print(patient.weight_pounds, 'lbs')
#below print statement for taking the values height_inches and weight_pounds as input from user
patient.height_inches = int(input())
patient.weight_pounds = int(input())
#below are the print statements that will be displayed on output screen to show that patient data after with the values of height_inches and weight_pounds input by the user
print('Patient data (after):', end=' ')
print(patient.height_inches, 'in,', end=' ')
print(patient.weight_pounds, 'lbs')
Another way to write the solution is:
def __init__(self):
self.height_inches = 0
self.weight_pounds = 0
self keyword is the keyword which is used to easily access all the attributes i.e. height_inches and weight_pounds defined within a PatientData class.
__init__ is a constructor which is called when an instance is created from the PatientData, and access is required to initialize the attributes height_inches and weight_pounds of PatientData class.
The program along with its output is attached.
In this exercise we have to use the knowledge of computational language in python to describe a code, like this:
The code can be found in the attached image.
To make it easier the code can be found below as:
class PatientData():
height_inches=0
weight_pounds=0
patient = PatientData()
print('Patient data (before):', end=' ')
print(patient.height_inches, 'in,', end=' ')
print(patient.weight_pounds, 'lbs')
patient.height_inches = int(input())
patient.weight_pounds = int(input())
print('Patient data (after):', end=' ')
print(patient.height_inches, 'in,', end=' ')
print(patient.weight_pounds, 'lbs')

Describe how asymmetric encryption is used to send a message from User A to User B that assures data confidentiality, authentication, and integrity. Be specific as to the keys used and how they achieve the three goals.
Answers
Answer:
Find the explanation below.
Explanation:
Asymmetric encryption is a system of communication in technology between two parties where keys which are variable values coined by an algorithm are used to encrypt and decrypt the messages between the sender and receiver. The two types of keys used in this process are the public and private keys. The public keys can be used by anyone to encrypt messages which are then sent to the receiver who decrypts the message using his private keys. The private keys on the other hand are only shared by the person who first set up the key. In sending messages this way, the receiver's public key is gotten from a public directory, and the message encrypted by the sender. The receiver can then decrypt the message using his private keys. But if the message is encrypted using a private key, it is decrypted by the receiver with a public key.
The one-way nature of this style of communication ensures data integrity and confidentiality since users are not required to disclose their keys and only the two parties can access the message. The two end users also preserve the right to authenticate the keys. The transport layer security protocol makes use of asymmetric encryption.
If our HMap implementation is used (load factor of 75% and an initial capacity of 1,000), how many times is the enlarge method called if the number of unique entries put into the map is:_______
a. 100
b. 750
c. 2,000
d. 10,000
e. 100,000
Answers
Answer:
A) for 100 : < 1 times
b) for 750 : < 1 times
c) For 2000 = 1 time
D) for 10000 = 4 times
E) for 100000 = 7 times
Explanation:
Given data:
load factor = 75%
initial capacity = 1000
The number of times the enlarge method will be called for a unique number of entries would be 2 times the initial capacity ( 1000 ) because the load factor = 75% = 0.75
A) for 100 : < 1 times
b) for 750 : < 1 times
C) For 2000
= initial capacity * 2 = 2000 ( 1 time )
D) for 10000
= 1000 * 2 *2 *2*2 = 16000 ( 4 times )
to make it 10000 we have to add another 2000 which will make the number of times = 4 times
E)for 100000
= 1000*2*2*2*2*2*2*2= 128000 ( 7 times )
unique entry of 100000 is contained in 7 times

What should be the bit destuffing rules at the receiver? Fill in the blank to show what is the stream after bit stuffingWrite the rule for stuffing:Write the rule for destuffing:Assume the user data stream before bit stuffing is 011111100011111101. What is the stream after bit stuffing?
Answers
Answer:
Explanation:
Bit stuffing Framing Method
In the given situation, the beginning casing is shown by 6 sequential ones followed by 2 zeroes.
The beginning casings are generally known as the flags.which are utilized for demonstrating the beginning and end of the edges. Essentially utilized for the synchronization between the sender and the reciever.
Along these lines here the beginning and end banners are 11111100(this is on the grounds that the end banner is same as the beginning banner).
To enable us understand how this question plays out, let us understand the rule for Stuffing and De-stuffing .
The standard for stuffing is :
At whatever point there are 5 successive ones supplement one zero in the casing which is an information. The embedded zero piece is known as the stuffed bit.The principle reason behind stuffing somewhat after 5 back to back ones is to evade the distortion of information (data) as flag. If the reciever misconstrues the information as end banner then he would quit recieving the information where the entire information sent by the sender will be left and lost causing an error-prone information.
The rule for destuffing :
The standard/rule for destuffing is only inverse as stuffing. After recieving the bitstuffed information (data), at the reciever's end zero after each 5 continuous ones will be evacuated and the rest of the information will be considered as the genuine information.
In the given situation, the beginning casing is demonstrated by 6 back to back ones followed by 2 zeroes.
the beginning casings are normally known as the flags.which are utilized for showing the beginning and end of the edges. Essentially utilized for the synchronization between the sender and the receiver.
In this way here the beginning and end banners are 11111100(this is on the grounds that the end banner is same as the beginning banner).
data before bit stuffing is: 011111100011111101the stream after stuffing would be: 01111101000111101101where the bolded/underlined digits represents the stuffed bits

Open endedness means whether one solution or answer is possible. In other words it means that there may be various ways and alternatives to solve or answer a question or bring solution to an investigation.
From the definition, we can deduce that an open ended investigation is a practical investigation that requires students to utilize procedural and substantive skills in arriving at conclusion through evidence gathered from open ended research or experiment(as in not close ended, not limited to ready made options, freedom to explore all possibilities). This is seen in the example question where students are asked to explore the different examples of physical controls and displays and also discuss their observations.

Describe and compare imperative (C), functional (SML) and logic (Prolog) programming paradigms.
Answers
Answer:
Answered below
Explanation:
Imperative programming paradigm is a paradigm in which the programmer tells the machine how to change its state. It is divided into procedural programming, where programs are grouped as procedures, and object-oriented, where programs are grouped together with the properties they operate on.
Imperative paradigm is efficient, familiar and popular compared to others.
Functional programming paradigm implements all instructions as functions, in a mathematical sense. They take on an argument and return a single solution. The advantage of this, compared to other paradigms, is its abstraction and independence.
Logical programming, like functional programming, incorporates a declarative approach to problem solving. All known facts are first established before queries are made. Advantage of this paradigm is that programming steps are kept to a minimum.

Answer:
No-force policy
Explanation:
The policy that allows a transaction to commit even if it has modified some blocks that have not yet been written back to disk is called the _NO-FORCE_ policy.
In data theory, the No-Force Policy is beneficial for the control of transaction. In this policy, when a transaction commits, changes that are made are not required to be written to disk in place. The changes recorded are preserved in order to make transaction durable. The recorded changes must be preserved at commit time.

In order to declare the required struct in the question, you need to type the keyword struct, then the name of the struct - PatientData, opening curly brace, data members - int heightInches, weightPounds;, closing curly brace and a semicolon at the end.
Note that since the object - lunaLovegood, is declared in the main function, we do not need to declare it in the struct. However, if it was not declared in the main, then we would need to write lunaLovegood between the closing curly brace and the semicolon.

}
return lastIndex;
}
Explanation:
This defines the method
public static int lastIndexOf(int [] numbers, int num){
This initializes the lastIndex to the first element of the array
int lastIndex = numbers[0];
This iterates through every "num" element of the array
for(int i =0; i<numbers.length;i+=num){
This gets the current index... until the last
lastIndex = numbers[i]; }
This returns the last
return lastIndex; }
