Data abstraction, inheritance, encapsulation, interface, and polymorphism are key concepts in object-oriented programming.
Data abstraction focuses on hiding the implementation details and showing only the necessary information to the user.
Inheritance allows a class to inherit properties and behavior from another class.
Encapsulation involves bundling data and methods that operate on the data into a single unit.
Interface...
Array.clone creates a shallow copy of an array, while Array.CopyTo copies elements from one array to another.
Array.clone creates a shallow copy of an array, meaning it creates a new array with the same elements as the original array.
Array.CopyTo copies elements from one array to another array. It takes two parameters - the source array and the destination array.
Example: string[] originalArray = {"apple", "banana", "che...
The 'is' and 'as' operators are used in C# to check the type of an object and perform type casting respectively.
The 'is' operator checks if an object is of a certain type and returns a boolean value.
The 'as' operator performs a safe type conversion and returns null if the conversion is not possible.
Example: if(obj is MyClass) { // do something }
Example: MyClass myObj = obj as MyClass;
finalize() is a method in Java used for cleanup operations before an object is garbage collected, while dispose() is a method used for releasing unmanaged resources in .NET.
finalize() is a method in Java that is called by the garbage collector before an object is reclaimed. It is used for cleanup operations like closing files or releasing resources.
dispose() is a method in .NET that is used for releasing unmanaged reso...
Boxing is the process of converting a value type to a reference type, while unboxing is the process of converting a reference type to a value type.
Boxing is done implicitly by the compiler when a value type is assigned to a variable of type object.
Unboxing requires explicit casting from the object type to the original value type.
Boxing and unboxing can impact performance as they involve memory allocation and type conve
Serialization is the process of converting an object into a format that can be easily stored or transmitted.
Serialization is used to convert complex data structures or objects into a stream of bytes for storage or transmission.
It allows the object to be reconstructed later by deserialization.
Common formats for serialization include JSON, XML, and binary formats like Protocol Buffers.
Example: Converting a Java object in
Dependency property is a specialized type of property in WPF that allows for data binding, styling, and animation.
Used for data binding, styling, and animation in WPF
Supports value inheritance, change notification, and default values
Defined as static fields in a class using DependencyProperty.Register method
Data binding in WPF allows synchronization of data between UI elements and data sources.
Data binding can be done using XAML markup or code-behind
Types of data binding include one-way, two-way, and one-time
Data binding can be used to bind UI elements to properties of data objects
Example:
Attached properties in WPF allow you to attach a value to an element that can be inherited by its children.
Attached properties are defined as static fields in a class and registered using the DependencyProperty.RegisterAttached method.
They are typically used to provide additional functionality to existing controls without subclassing them.
An example of an attached property is Grid.Row, which is used to specify the row ...
Triggers in WPF are used to change the appearance or behavior of a control in response to a specific event or condition.
Triggers allow you to define changes to a control's properties based on certain conditions.
They can be used to change the visual state of a control in response to user interactions or data changes.
Triggers can be defined in XAML and are commonly used for animations, data validation, and styling.

The task is to distribute candies to students based on their performance while minimizing the total candies distributed.
Create an array to store the minimum candies required for each student.
Iterate through the students' ratings array to determine the minimum candies needed based on the adjacent ratings.
Consider both left-to-right and right-to-left passes to ensure fair distribution.
Keep track of the total candies dist
You are given a sequence of numbers, ARR

in non-descending order using the Merge Sort algorithm.
The Merge Sort...
Implement Merge Sort algorithm to sort a sequence of numbers in non-descending order.
Use Divide and Conquer approach to recursively divide the input array into two halves.
Merge the sorted halves to produce a completely sorted array.
Ensure the implementation handles the constraints specified in the problem statement.
Example: For input [3, 1, 4, 1, 5], the output should be [1, 1, 3, 4, 5].
