Singleton is a design pattern that restricts the instantiation of a class to one object and provides a global point of access.
Singleton ensures that only one instance of a class is created and provides a way to access it globally.
It is thread-safe because the instance is created only once and accessed through a synchronized method or block.
Singleton can be implemented using different approaches such as eager initializa...
Object class is the base class of all classes in C#.
Object class provides basic functionalities like ToString(), GetHashCode(), and Equals() to all classes.
All classes in C# implicitly inherit from Object class.
Object class is defined in System namespace.
Example: class MyClass : Object { }
Access modifiers in C# control the visibility and accessibility of class members.
Public: accessible from anywhere
Private: accessible only within the class
Protected: accessible within the class and derived classes
Internal: accessible within the same assembly
Protected Internal: accessible within the same assembly and derived classes
Example: public int age; private string name;
Example: protected void DoSomething(); intern
Default access modifiers are public, protected, and private.
Public: accessible from anywhere
Protected: accessible within the class and its subclasses
Private: accessible only within the class

Components of a service include functionality, reliability, availability, and performance.
Functionality: The service should perform the intended tasks and meet the requirements.
Reliability: The service should consistently deliver the expected results.
Availability: The service should be accessible and operational when needed.
Performance: The service should perform efficiently and meet performance expectations.
The lifecycle of a web API refers to the stages it goes through from development to retirement.
The lifecycle typically includes stages like planning, development, testing, deployment, and retirement.
During planning, the requirements and design of the API are defined.
Development involves writing the code and implementing the functionality.
Testing ensures the API works as expected and meets the requirements.
Deployment in...

Round duration - 60 minutes
Round difficulty - Medium
Technical Interview round with questions on C#, Design patterns, OOPS etc.
A base class is a class that is used as a starting point for creating other classes. It can be inherited by other classes.
Base class provides common attributes and methods that can be inherited by other classes
Derived classes can extend or override the functionality of the base class
Example: Animal can be a base class with attributes like name and methods like eat, sleep
Singleton design pattern ensures a class has only one instance and provides a global point of access to it.
Used to restrict the instantiation of a class to one object
Commonly used in logging, caching, thread pools, database connections
Implemented by creating a static instance of the class and a private constructor to prevent external instantiation
Access modifiers in C# control the visibility and accessibility of classes, methods, and other members.
Public - accessible from any other class or assembly
Private - accessible only within the same class
Protected - accessible within the same class or derived classes
Internal - accessible within the same assembly
Protected Internal - accessible within the same assembly or derived classes
The default access modifier in C# is 'private'.
Default access modifier is applied if no access modifier is specified for a class member
It restricts the access to the member within the same class
Example: private int myVariable = 10;

Boundary traversal of a tree is the process of visiting the nodes on the boundary of a tree in a specific order.
The boundary traversal can be done in three steps: left boundary, leaf nodes, and right boundary.
For the left boundary, start from the root and traverse down the left side of the tree until reaching a leaf node.
For the leaf nodes, perform an inorder traversal to visit all the leaf nodes of the tree.
For the ri...
Find the nearest greater value of a given value in a Binary Search Tree (BST).
Start from the root node and compare the given value with the current node's value.
If the given value is less than the current node's value, move to the left subtree.
If the given value is greater than the current node's value, move to the right subtree.
Keep track of the closest greater value encountered while traversing the tree.
Return the cl
Given an infinite staircase with a broken kth step, find the maximum height we can reach in n rounds of jumping i steps.
We can start by jumping the maximum number of steps in each round until we reach the broken step.
After reaching the broken step, we can discard the i steps that would land us on the broken step and jump the remaining steps.
We can continue this pattern until we reach the maximum height we can reach wit
