- Q1. Find longest palindromic substring in a given string.
- Ans.
Use dynamic programming to find the longest palindromic substring in a given string.

Store the length of the longest palindrome found so far.
Return the substring based on the start and end indices of the longest palindrome.
- Q2. How to serialize and deserialise a tree
- Ans.
To serialize and deserialize a tree, use a recursive approach to traverse the tree and store the data in a suitable format.
Use pre-order traversal to serialize the tree by storing the node values in a list or string.
For deserialization, reconstruct the tree by recursively building nodes from the serialized data.
Consider using JSON or XML format for serialization to easily store and retrieve tree structure.
- Q3. Find if a given regex (containing ., * and lower case english chars) matches a given string.

- Q2. Write a short promise example and implement your own promise
- Ans.
A promise is a commitment to do something in the future, typically used for asynchronous operations in JavaScript.
Promises are used to handle asynchronous operations in JavaScript.
They represent a value that may be available now, in the future, or never.
Promises have three states: pending, fulfilled, or rejected.
Example: new Promise((resolve, reject) => { setTimeout(() => resolve('Done!'), 1000); });
- Q3. Explain event loop, what are different types of queues in event loop
- Ans.
Event loop is a mechanism that allows for asynchronous execution of code by managing the order of events in a single thread.
Event loop continuously checks the call stack for any functions that need to be executed, and processes them in a non-blocking manner.
Different types of queues in event loop include microtask queue (Promise callbacks), macrotask queue (setTimeout, setInterval callbacks), and animation frame queue
- Q4. What is virtual DOM and why its faster
- Ans.
Virtual DOM is a lightweight copy of the actual DOM, used to improve performance by minimizing direct manipulation of the real DOM.
Virtual DOM is a concept used in frameworks like React to optimize rendering performance.
Changes are first made to the virtual DOM, which is then compared to the real DOM to identify the minimal updates needed.
This approach reduces the number of actual DOM manipulations, resulting in faster...

- Q1. Why do we use SOLID principle, SRP and OCP violation?
- Ans.
SOLID principles help in creating maintainable, scalable, and flexible software.
SOLID principles help in creating software that is easier to maintain and extend.
Single Responsibility Principle (SRP) ensures that a class has only one reason to change, leading to more modular and cohesive code.
Open/Closed Principle (OCP) states that a class should be open for extension but closed for modification, allowing for easy chang...
- Q2. What is singleton design pattern and how to implement it?
- Ans.
Singleton design pattern ensures a class has only one instance and provides a global point of access to it.
Create a private static instance of the class within the class itself.
Provide a public static method to access the instance.
Ensure the constructor of the class is private to prevent instantiation from outside the class.
Example: Singleton pattern is commonly used in database connections to ensure only one connectio
- Q3. OOPs based question: abstract vs interface, multiple inheritance, method overloading vs method overriding.
- Q4. Dependency injection- what is it and any use case where to use?
- Ans.
Dependency injection is a design pattern where components are provided with their dependencies rather than creating them internally.
Dependency injection helps in achieving loose coupling between components.
It makes components easier to test by allowing for easier mocking of dependencies.
Use cases include injecting database connections, logging services, and external API clients into components.

- Q3. Data seeding in entity framework and how to map tables with entity?
- Ans.
Data seeding in Entity Framework involves pre-populating database tables with initial data. Mapping tables with entities involves defining relationships between database tables and entity classes.
Data seeding in Entity Framework can be done using the 'Seed' method in the 'Configuration' class of the DbContext.
To map tables with entities, use data annotations or Fluent API to define relationships between entities and da...
