    Defination: Maximize total value of items without exceeding weight limit using given weights and values.

    def knapsack(values,weights,capacity):

   n=len(values)
   dp=[[0 for _ in range(capacity+1)] for _ in range(n+1)]
   #Fill the dp array
   for i in range(1,n+1):
      for w in range(1,capacity+1):
          if weights[i-1]<=w:
             dp[i][w]=max(dp[i-1][w],dp[i-1][w-weights[i-1]]+values[i-1])
          else:
             dp[i][w]=dp[i-1][w]
   #The maximum value is in the bottom-right corner of the dp array
   return dp[n][capacity]
values=[60,100,120]
weights=[10,20,30]
capacity=50
max_value=knapsack(values,weights,capacity)
print(f"The maximum value that can be obtained is: {max_value}")

    Explanation:

    1. Initialization:
      • We initialize a 2D list dp where dp[i][w] represents the maximum value that can be obtained using the first i items with a total weight not exceeding w.
    2. Filling the DP Table:
      • For each item i (from 1 to n), and for each weight w (from 1 to capacity):
        • If the weight of the item i (weights[i-1]) is less than or equal to w, we have two choices:
          • Exclude the item i: The value is dp[i-1][w].
          • Include the item i: The value is dp[i-1][w-weights[i-1]] + values[i-1].
        • We take the maximum of these two choices.
        • If the weight of the item i is greater than w, we exclude the item i.
    3. Result:
      • The maximum value that can be obtained is found in dp[n][capacity].

    Different teaching methodologies significantly impact student learning outcomes and engagement levels. Lecture-based instruction, a traditional method, often results in passive learning where students may struggle with retention and critical thinking. While it efficiently delivers information to large groups, it may not cater to diverse learning styles or foster deep understanding.

    In contrast, collaborative learning involves students working together to solve problems, enhancing their understanding, retention, and critical thinking skills. This method promotes active participation and motivation as students learn from each other, leading to a more dynamic classroom environment.

    Problem-based learning (PBL) centers on real-world problems, encouraging students to apply knowledge critically and creatively. PBL boosts engagement and motivation, as students see the relevance of their studies. This method also enhances teacher-student interaction, as instructors guide and facilitate rather than merely deliver content.

    Technology-enhanced learning incorporates digital tools, making education more interactive and accessible. It caters to various learning styles through multimedia resources and allows for personalized learning experiences. This approach can increase student motivation and participation, though it requires careful implementation to avoid distractions.

    Overall, these methodologies influence classroom dynamics, fostering a more interactive and inclusive environment. Effective teaching often involves blending these methods to address the diverse needs of students, promoting a holistic learning experience.

    Normalization in relational database design is the process of organizing data to reduce redundancy and improve data integrity. It involves structuring a database to ensure data dependencies are logical, thus enhancing efficiency and consistency.

    First Normal Form (1NF)

    1NF requires that each column contains only atomic values, meaning each cell has a single value, and each record is unique. This simplifies data manipulation and querying.

    Second Normal Form (2NF)

    2NF builds on 1NF by ensuring that all non-key attributes are fully dependent on the primary key. This eliminates partial dependencies, reducing redundancy by separating data into related tables.

    Third Normal Form (3NF)

    3NF further refines the structure by ensuring that non-key attributes are dependent only on the primary key and not on other non-key attributes. This removes transitive dependencies, further reducing redundancy and potential anomalies.

    Importance

    Normalization improves database integrity by organizing data logically, which reduces redundancy and the risk of anomalies during data operations. It enhances efficiency by optimizing the database structure, leading to faster query performance and easier maintenance. Overall, normalization is essential for a clean, efficient, and reliable database system.

    Polymorphism in Object-Oriented Programming allows methods to do different things based on the object it is acting upon, even if they share the same name. It lets one interface be used for a general class of actions, making code more flexible and reusable.

    Imagine you have a book class with a method called “summary()”. If you create two types of books, “novel” and “biography”, each type can have its own version of “summary()”. When you use the “summary()” method on a book, it will show the right summary based on whether the book is a “novel” or a “biography”. Even though you use the same method name, it does different things depending on the type of book.

    class Book:
  def summary(self):
    return "This is a book."

class Novel(Book):
  def summary(self):
    return "This is a fictional story."

class Biography(Book):
  def summary(self):
    return "This is a real-life story."

novel = Novel()
biography = Biography()

print(novel.summary())
print(biography.summary())

    In this simpler code, the “summar()” method in the “book” class provides a general description, while the “novel” and “biography” classes override it with their specific summaries.
