which came first, the instance or the class?
Answers
In object-oriented programming, the class typically comes first before instances or objects. A class serves as a blueprint or template that defines the structure, behavior, and properties of objects. It encapsulates the common characteristics and functionalities that objects of that class will possess.
Once a class is defined, instances or objects can be created based on that class. Each instance is a specific realization or instantiation of the class, representing a unique entity with its own set of values for the class's attributes.
In simpler terms, you can think of a class as a blueprint for a house, outlining its design and features, while instances are the actual houses built based on that blueprint. The class defines the properties and behaviors of the objects, and the instances are the specific objects that exist based on that class.
Therefore, the class comes first in terms of conceptualization and definition, and then instances are created based on that class.

Answers
Answer:
One such sign to look for is in the URL of the website. A secure website's URL should begin with “https” rather than “http”. The “s” at the end of “http” stands for secure and is using an SSL (Secure Sockets Layer) connection. Your information will be encrypted before being sent to a server.
T - True. One way to check if a website is secure is to look for a padlock icon in the address bar.
How does this work?This padlock indicates that the website is using a secure HTTPS connection. HTTPS encrypts the data transmitted between the user's browser and the website, ensuring that sensitive information such as login credentials or financial details remains private and protected from unauthorized access.
Additionally, a secure website's address will start with "https://" instead of "http://". Users should always verify these security indicators before entering any personal or sensitive information on a website to safeguard their online privacy and security.

In the MoMA learning module investigating identity, artists who used their bodies in performances were not trying to:

2. Conform to traditional art practices: These artists did not adhere to conventional methods of art-making, such as painting or sculpture. Instead, they utilized their bodies as a medium to convey their ideas and explore the complexities of identity.
3. Distance themselves from their work: Unlike some artists who may create art that is separate from their personal experiences, these artists engaged with their own bodies and personal narratives. They used their performances as a means to express their individual identities and share their stories.
4. Maintain a passive role: The artists who used their bodies in performances did not passively present themselves to the audience. Rather, they actively engaged with the viewers, often challenging them to question their preconceived notions about identity and societal norms.
5. Create static representations: The use of their bodies allowed these artists to convey dynamic and ever-evolving aspects of identity. Through performances, they could explore the fluidity and complexity of identity, highlighting how it can change and be influenced by various factors.

recurrence equation that describes the running time of quicksort when assuming that the pivot is always placed in the middle of the array
T(N)=T(N/2)+ N T(N)=2*T(N/2)+N none of the others T(N)=T(N/2)+ 1 T(N)=2*T(N/2) + 1
Answers
The recurrence equation that describes the running time of quicksort when assuming that the pivot is always placed in the middle of the array is T(N)=2*T(N/2)+N.
When the pivot is placed in the middle of the array, the partition step will divide the array into two halves of roughly equal sizes. Each subarray will then be recursively sorted using quicksort. Since the pivot is always in the middle, the partition step will always result in dividing the array into two subarrays of size N/2. Therefore, the recurrence equation becomes T(N)=2*T(N/2)+N, where T(N/2) represents the running time for each subarray of size N/2 and N represents the cost of the partition step.
The recurrence equation T(N)=2*T(N/2)+N can be solved using the master theorem, which is a general method for solving recurrence equations of the form T(N)=a*T(N/b)+f(N), where a and b are constants and f(N) is some function. In this case, a=2, b=2, and f(N)=N. The master theorem has three cases depending on the relationship between a, b, and f(N). In our case, we have f(N)=N and b=2, so we are in the second case of the master theorem. The second case states that if f(N) is O(N^c) for some constant c

The recurrence equation that describes the running time of quicksort when assuming that the pivot is always placed in the middle of the array is:
T(N) = 2 * T(N/2) + N
In this equation:
- T(N) represents the running time of quicksort on an array of size N.
- The term T(N/2) represents the running time of quicksort on the two subarrays created by partitioning the original array.
- The term N represents the time taken to partition the array around the pivot.
This recurrence equation states that the running time of quicksort is proportional to twice the running time on half the input size (since we divide the array into two subarrays), plus the time taken for partitioning the array.
Note: Other variations of the quicksort algorithm may have different recurrence equations depending on how the pivot is chosen and how the partitioning is performed.
