OR, IF, NOT,AND are the examples of logical test arguments used in formulas
What function is used for logical testing?The IF function, for instance, runs a logical test and returns one value if the result is TRUE and a different value if the result is FALSE. In logical operations, a logical test is used to assess the contents of a cell location.The logical test's findings can be either true or untrue.For instance, depending on the value entered into cell C7, the logical test C7 = 25 (read as "if the value in cell C7 is equal to 25") may or may not be true. A logical test entails the system checking for a predetermined condition, and if it does, it will present the results in Excel in accordance with logic.If a student receives more than 35 marks, for example, we can consider them to have passed; otherwise, they would have failed. The most well-known member of the family of logic functions is the AND function.It is useful when you need to test multiple conditions and make sure they are all met.Technically, the AND function evaluates the conditions you provide and returns TRUE if every condition does, else FALSE.To learn more about logical testing refer

Ramshewak goes to market for buying some fruits and vegetables. He ishaving a currency of Rs 500 with him for marketing. From a shop he purchases 2.0 kg Apple priced Rs. 50.0 per kg, 1.5 kg Mango priced Rs.35.0 per kg, 2.5 kg Potato priced Rs.10.0 per kg, and 1.0 kg Tomato priced Rs.15 per kg. He gives the currency of Rs. 500 to the shopkeeper. Find out the amount shopkeeper will return to Ramshewak. and also tell the total item purchased. write the algorithm to the problem
Answers
Answer:
Explanation:
To find the amount that the shopkeeper will return to Ramshewak and the total items purchased, we can use the following algorithm:
Set the initial amount paid by Ramshewak to the shopkeeper as 500.
Calculate the cost of 2.0 kg of apples at Rs. 50 per kg: 2.0 x 50 = 100
Add the cost of apples to the initial amount: 500 + 100 = 600
Calculate the cost of 1.5 kg of mangoes at Rs. 35 per kg: 1.5 x 35 = 52.5
Add the cost of mangoes to the total amount: 600 + 52.5 = 652.5
Calculate the cost of 2.5 kg of potatoes at Rs. 10 per kg: 2.5 x 10 = 25
Add the cost of potatoes to the total amount: 652.5 + 25 = 677.5
Calculate the cost of 1.0 kg of tomatoes at Rs. 15 per kg: 1.0 x 15 = 15
Add the cost of tomatoes to the total amount: 677.5 + 15 = 692.5
Subtract the total amount from the initial amount paid by Ramshewak to find the amount that the shopkeeper will return: 500 - 692.5 = -192.5
Since the total amount of the items purchased is Rs. 692.5 and Ramshewak paid Rs. 500, the shopkeeper will return Rs. 192.5 to Ramshewak.
Algorithm:
Set initial amount paid by Ramshewak to 500
Calculate cost of 2.0 kg of apples at Rs. 50 per kg
Add cost of apples to the initial amount
Calculate cost of 1.5 kg of mangoes at Rs. 35 per kg
Add cost of mangoes to the total amount
Calculate cost of 2.5 kg of potatoes at Rs. 10 per kg
Add cost of potatoes to the total amount
Calculate cost of 1.0 kg of tomatoes at Rs. 15 per kg
Add cost of tomatoes to the total amount
Subtract total amount from initial amount paid by Ramshewak to find amount shopkeeper will return to Ramshewak.
Given main.py and a Node class in Node.py, complete the LinkedList class (a linked list of nodes) in LinkedList.py by writing the insert_in_ascending_order() method that inserts a new Node into the LinkedList in ascending order.
Ex: If the input is:
8 3 6 2 5 9 4 1 7
the output is:
1 2 3 4 5 6 7 8 9
So, after finagling and wracking my brain I've gotten to this point with the code, but here's the issue;
Here's the code:
class LinkedList:
def __init__(self):
self.head = None
self.tail = None
def append(self, new_node):
if self.head == None:
self.head = new_node
self.tail = new_node
else:
self.tail.next = new_node
self.tail = new_node
def prepend(self, new_node):
if self.head == None:
self.head = new_node
self.tail = new_node
else:
new_node.next = self.head
self.head = new_node
def insert_after(self, current_node, new_node):
if self.head == None:
self.head = new_node
self.tail = new_node
elif current_node is self.tail:
self.tail.next = new_node
self.tail = new_node
else:
new_node.next = current_node.next
current_node.next = new_node
def insert_in_ascending_order(self, new_node):
if self.head == None or new_node.data < self.head.data:
new_node.next = self.head
self.head = new_node
else:
cur_node = self.head
while cur_node.next != None and new_node.data > cur_node.next.data:
cur_node = cur_node.next
cur_node.next = new_node
def remove_after(self, current_node):
# Special case, remove head
if (current_node == None) and (self.head != None):
succeeding_node = self.head.next
self.head = succeeding_node
if succeeding_node == None: # Remove last item
self.tail = None
elif current_node.next != None:
succeeding_node = current_node.next.next
current_node.next = succeeding_node
if succeeding_node == None: # Remove tail
self.tail = current_node
def print_list(self):
cur_node = self.head
while cur_node != None:
cur_node.print_node_data()
print(end=' ')
cur_node = cur_node.next
Here's the INPUT:
8 3 6 2 5 9 4 1 7
Here's my OUTPUT:
1 2 7
What can I do? Why does it only output 3 integers? I feel like the issue must be in my def remove_after section, however that was base code in the assignment (which I'm not necessarily supposed to change).
Answers
```python
cur_node.next = new_node
```
This line is incorrectly assigning the new node directly to the `cur_node.next`, which causes the previous nodes to be lost and results in a truncated list.
To fix this issue, you need to rearrange the statements in the `else` block as follows:
```python
new_node.next = cur_node.next
cur_node.next = new_node
```
This way, you correctly set the `next` references of the new node and the current node, preserving the integrity of the linked list.
Here's the corrected `insert_in_ascending_order()` method:
```python
def insert_in_ascending_order(self, new_node):
if self.head is None or new_node.data
Create a Python program that prints all the numbers from 0 to 4 except two distinct numbers entered by the user.
Note : Use 'continue' statement.
Answers
Here is a Python program that prints all numbers from 0 to 4, excluding two distinct numbers entered by the user, using the 'continue' statement:
```python
numbers_to_exclude = []
# Get two distinct numbers from the user
for i in range(2):
num = int(input("Enter a number to exclude: "))
numbers_to_exclude.append(num)
# Print numbers from 0 to 4, excluding the user-entered numbers
for i in range(5):
if i in numbers_to_exclude:
continue
print(i)
```
The program first initializes an empty list called `numbers_to_exclude` to store the two distinct numbers entered by the user.
Next, a loop is used to prompt the user to enter two distinct numbers. These numbers are appended to the `numbers_to_exclude` list.
Then, another loop is used to iterate through the numbers from 0 to 4. Inside the loop, an 'if' condition is used to check if the current number is in the `numbers_to_exclude` list. If it is, the 'continue' statement is executed, which skips the current iteration and proceeds to the next iteration of the loop.
If the current number is not in the `numbers_to_exclude` list, the 'print' statement is executed, and the number is printed.
This program ensures that the two distinct numbers entered by the user are excluded from the output, while all other numbers from 0 to 4 are printed.

A contact list is a place where you can store a specific contact with other associated information such as a phone number, email address, birthday, etc. Write a program that first takes as input an integer N that represents the number of word pairs in the list to follow. Word pairs consist of a name and a phone number (both strings), separated by a comma. That list is followed by a name, and your program should output the phone number associated with that name. Output "None" if name is not found. Assume that the list will always contain less than 20 word pairs.
Ex: If the input is:
3 Joe,123-5432 Linda,983-4123 Frank,867-5309 Frank
the output is:
867-5309
Your program must define and call the following method. The return value of getPhoneNumber() is the phone number associated with the specific contact name.
public static String getPhoneNumber(String[] nameArr, String[] phoneNumberArr, String contactName, int arraySize)
Hint: Use two arrays: One for the string names, and the other for the string phone numbers.
Answers
Answer: import java.util.Scanner;
public class ContactList {
public static void main(String[] args) {
Scanner scnr = new Scanner(System.in);
// Read the number of word pairs in the list
int n = scnr.nextInt();
scnr.nextLine(); // Consume the newline character
// Read the word pairs and store them in two arrays
String[] names = new String[n];
String[] phoneNumbers = new String[n];
for (int i = 0; i < n; i++) {
String[] parts = scnr.nextLine().split(",");
names[i] = parts[0];
phoneNumbers[i] = parts[1];
}
// Read the name to look up
String name = scnr.nextLine();
// Call the getPhoneNumber method to look up the phone number
String phoneNumber = getPhoneNumber(names, phoneNumbers, name, n);
// Print the phone number, or "None" if the name is not found
if (phoneNumber != null) {
System.out.println(phoneNumber);
} else {
System.out.println("None");
}
}
public static String getPhoneNumber(String[] nameArr, String[] phoneNumberArr, String contactName, int arraySize) {
// Search for the name in the array and return the corresponding phone number
for (int i = 0; i < arraySize; i++) {
if (nameArr[i].equals(contactName)) {
return phoneNumberArr[i];
}
}
// If the name is not found, return null
return null;
}
}
Explanation: The program inputs the number of word sets, stores them in two clusters (names and phoneNumbers), and looks up a title by calling the getPhoneNumber strategy to return the comparing phone number. Prints phone number or "None" in the event that title not found. getPhoneNumber strategy takes nameArr, phoneNumberArr, contactName, and arraySize as contentions. The strategy looks for a title and returns the phone number in case found, something else invalid.

The given below is the code for the given scenario.
What is Inheritance?
Inheritance allows you to define a class that inherits all its methods and properties from another class. The parent class is the class from which it inherits, also called the base class. A child class is a class that inherits from another class, also called a derived class.
Code:
class Professional_Sports_Team:
# Directory class will create an object that stores the team name,
# home city and sport played.
def __init__(self, team_name, home_city, sport):
self.__team_name = team_name
self.__home_city = home_city
self.__sport = sport
# Mutators/Setters
def set_team_name(self, team_name):
self.__team_name = team_name
def set_home_city(self, home_city):
self.__home_city = home_city
def set_sport(self, sport):
self.__sport = sport
# Accessors/Getters
def get_team_name(self):
return self.__team_name
def get_home_city(self):
return self.__home_city
def get_sport(self):
return self.__sport
# MLB Teams subclass should inherit from the Professional Sports Team class MLB_Team(Professional_Sports_Team):
def __init__(self, team_name, home_city, sport, mascot,team_batting_average, team_pitching_ERA):
# call super class constructor
super(MLB_Team, self).__init__(team_name, home_city,sport) self.____mascot = mascot
self.__team_batting_average = team_batting_average self.__team_pitching_ERA = team_pitching_ERA
# This method assigns a string to the __mascot field.
def set_mascot(self, mascot):
self.____mascot = mascot
# This method assigns a value to the __team_batting_average field.
def set_team_batting_average(self, team_batting_average): self.__team_batting_average = team_batting_average
# This method assigns a value to the __team_pitching_ERA field.
def set_team_pitching_ERA(self, set_team_pitching_ERA): self.__team_pitching_ERA = set_team_pitching_ERA
# This method returns the string of the __mascot field.
def get_mascot(self):

Consider a logical address space with 32 pages, how many bits must be used to represent the page number in the logical address?
Answers
Question:
Consider a logical address space with 32 pages of 1024 words, how many bits must be used to represent the page number in the logical address?
Answer:
15 bits.
Explanation:
Given:
A logical address space has 32 pages of 1024 words.
To represent these 32 pages, 5 bits are needed. i.e
32 = 2⁵
Also, each page contains 1024 words. This means that 10 bits will be needed for addressing within each 1024-word page. i.e
1024 = 2¹⁰
The total number of bits is the sum of the number of bits required for the pages and the number of bits required for addressing within each 1024-word page. i.e
5 + 10 = 15.
Therefore, the logical addresses must be 15 bits.

MyPltw 1.2.2 Hack Attack.
I need help on getting the PasswordNumberGuess label to show the numbers that are being tested. (Also for some reason, when I hack, the api says “error incorrect password” but when I retrieve the string it has been reset, why is that?)
Answers
To display the numbers being tested in the PasswordNumberGuess label, you can add the following code inside the for loop:
PasswordNumberGuess.Text = i.ToString();
How would this solve your problem?Considering the complication with the password reset, it is conceivable that the API has been configured to reset the password after a certain number of failed endeavors.
One should inspect the API documentation or communicate with the provider of the said service for additional exposure on this trait.
As an additional choice, mayhap there exists an error in your code resulting in unintentionally initiating the exclusion of the password. Consider perusing your program systematically to confirm that you are not automatically restarting the password.

Explanation:
There were 8 key changes made:
Added the missing include statements: <iostream> for input/output, <cstdlib> for srand, <ctime> for time, <cmath> for math functions, and <iomanip> for formattingAdded missing semicolons at the end of the cout statementsFixed the function prototypes and definitions to match their declarationsAdded missing closing angle brackets in srand(static_cast<unsigned>(time(0)));Changed the input prompt in the init function to use cin instead of scanfFixed the print function to display the values in a formatted manner and added line breaks every 10 elementsFixed the division in the stdX function to use (n - 1) instead of n - 1 to calculate the sample varianceAdded missing #include <iomanip> for the setprecision function used in print
