Suppose you have n classes that you want to schedule in rooms. Each class has a fixed time interval at which it is offered, and classes whose times overlap cannot be scheduled in the same room. There are enough rooms to schedule all the classes. Design a O(n log n) time algorithm to find an assignment of classes to rooms that minimizes the total number of rooms used.
Answer:
Function schedule( list of tuple of start and end times, class available)
class_list = create list of class from class available
for items in time_list:
if items is not same range as time_list[-1]:
newdict[items] = class_list[0]
print class time: class venue
elif items is same range as time_list[-1]:
used_class = newdict.values
index = class_list.index(used_class[-1])
new_dict[items] = class_list[index + 1 ]
print class time: class venue
Explanation:
The algorithm above describe a program with a time complexity of O(n log n). The function defined accepts two parameters, an array of start and end time tuple and the number of class available for use. The algorithm uses a quick sort to compare the time interval of the items in the list and schedule new classes for classes that overlaps with others.

_________________ component defines the correct granularity for access controls and oversees the relationships between identities, access control rights, and IT resource availability.
Answer:
Authorization component defines the correct granularity for access controls and oversees the relationships between identities, access control rights, and IT resource availability.
Explanation:
Access control is a security technique that verifies the permission that a person or device has to enter an area and to what extent. This function is within the identity and access management of a company. Authorization is the definition of what a specific user can do within an application, that is, to what information and operations they have access, in other words, it refers to the management of access to protected resources and the process of determining whether a user is authorized to access a particular resource. Authorization and access control are ways of enforcing access policies. Authorized persons may access certain resources for their job functions and identify and audit the accesses made.

Discuss two (2) methods for combining multiple anomaly detection methods to improve the identification of anomalous objects. You must consider both supervised and unsupervised cases in your discussion.
Answer:
Supervised anomaly detection is a process in data mining that uses a historic dataset of dependent variables and labeled independent variables to detect outliers or anomalies in the data been mined.
Unsupervised anomaly detection method uses unsupervised algorithms of unlabeled clusters to label and predicts and rule-out outliers or anomalies.
Explanation:
Anomaly detection is a method of identifying data or observations with high deviation or spread from other grouped data. Supervised and unsupervised machine learning algorithms are used to predict and detect abnormal datasets or outliers during data mining.
The supervised anomaly detection algorithm trains the model with a dataset, for the algorithm to derive a function it could use to predict outlier or anomalies. The unsupervised detection algorithm is able to cluster and label normal and abnormal data in the dataset, using this function to detect anomalies in future datasets.

I NEED THE ACTUAL CODE!!! 100 POINTS AND BRAINLIEST. REPORTING IF YOU DON'T ANSWER
Question 1:
Design a BankAccount Class with the following requirements:
1. Class variables
- Overdraft Fee = 20 (Overdraft fee is subtracted from the account when account balance is negative after a withdraw)
2. Object variables
- Balance (Balance is the amount of money an account has left)
3. Methods
- deposit(amount): Accepts an argument amount of type number, adds this amount to account's balance
- withdraw(amount): Accepts an argument amount of type number, subtract this amount to account's balance, if the resulting balance is negative, apply an Overdraft Fee on the account balance
Test your class to see if it works:
- Scenario 1:
- Create a new account called "college_checking", assign 1000 dollars to the initial balance.
- Withdraw 200 dollars
- Withdraw 500 dollars
- Deposit 100 dollars
- Withdraw 600 dollars
- Check your remaining balance, it should be -220 dollars of balance, because $1000 - $200 - $500 + $100 - $600 - $20(overdraft) = $-220
- Scenario 2:
- Create a new account called "europe_trip_fund", assign 0 dollars to the initial balance.
- Deposit 250 dollars
- Deposit 220 dollars
- Deposit 530 dollars
- Withdraw 721 dollars
- Check your remaining balance, it should be $279 dollars of balance, because $0 + $250 + $220 + $530 - $721 = $279
Question 2:
Design a OverdraftProtectionAccount that inherits from BankAccount Class with the additional requirements:
1. Methods
- withdrawal(amount): Accepts an argument amount of type number, subtract this amount to account's balance, if the resulting balance is negative, log an error message:
"There's insufficient funds in your account to complete this transaction"
to the terminal and stop the transaction so that your balance isn't overdrafted.
Test your OverdraftProtectionAccount class to see if it works:
- Scenario 3:
- Create a new account called "personal_checking", assign 100 dollars to the initial balance.
- Withdraw 20 dollars
- Withdraw 50 dollars
- Deposit 12 dollars
- Withdraw 60 dollars
- Check your remaining balance, it should be 42 dollars of balance, because $100 - $20 - $50 + $12 = $42, the last withdrawal didn't go through because that would leave your account balance negative.

An concept, assertion, or fact is communicated to the reader through a statement sentence, sometimes referred to as a declarative phrase. They are one of the four categories of sentence construction and the one that people utilize the most.
Direct access to instance variables and methods is made possible through instance methods. Through instance methods, class variables and class methods are easily available. Class methods provide direct access to class variables and class methods. When an object is generated, instance variables are created that are available to all of the constructors, methods, and blocks in the class. The instance variable can be given access modifiers.

Described how the HCS12 MCU uses a vector to find the correct interrupt service routine after an interrupt occurs.
Answer:
In the HC12 MCU, the starting address of interrupts is stored in the vector table as a vector. The ISR or interrupt service routine fetches the vector of the interrupt to be executed.
Explanation:
The HC12 or 68HC12 microcontroller was developed by Motorola, its controllers have a clock speed of between 8 to 33MHz.
The MCU stores interrupt events in a vector table where the interrupt service routine fetches enabled interrupt to execute.
When an interrupt is detected, the MCU stores all its registers in a stack to be able to return to the program it was previously running, then it disables the maskability flag register to prevent another maskable interrupt from occurring during the current interrupt execution.
The MCU interrupt service routine fetches the required interrupt from the vector table. After the interrupt is executed, the mask flag is enabled and the MCU retrieves or returns back to the previous program in the stack.
