- Q1. What are Data Annotations?
- Ans.
Data Annotations are attributes used in .NET Framework to provide metadata about data elements.
Data Annotations are used to validate data in models.
They can be used to specify data types, display names, and format strings.
Examples include [Required], [StringLength], and [RegularExpression].
- Q2. What are Solid Principles?
- Ans.
Solid Principles are a set of five design principles for writing maintainable and scalable software.

Open/Closed Principle (OCP)
Liskov Substitution Principle (LSP)
Interface Segregation Principle (ISP)
Dependency Inversion Principle (DIP)
- Q3. How would you tune a Stored Procedure?
- Ans.
To tune a Stored Procedure, identify bottlenecks, optimize queries, and use indexes.
Identify slow queries and optimize them
Use indexes to improve query performance
Avoid using cursors and temporary tables
Minimize network traffic by reducing data returned
Use SET NOCOUNT ON to reduce network traffic
Use stored procedure parameters instead of constants or variables
Use TRY/CATCH blocks to handle errors
Monitor performance usi...
- Q4. What is Routing in MVC?
- Ans.
Routing in MVC is the process of mapping URLs to controller actions.
Routing determines which controller and action should handle a request.
Routes are defined in the RouteConfig.cs file.
Routes can include parameters that are passed to the controller action.
Routes can also include constraints to limit which requests match the route.
Example: /products/5 maps to the ProductsController's Details action with id parameter 5.

- Q2. Find if a given directed graph is cyclic or not
- Ans.
To check if a directed graph is cyclic or not
Use Depth First Search (DFS) algorithm to traverse the graph
Maintain a visited set to keep track of visited nodes
Maintain a recursion stack to keep track of nodes in the current DFS traversal
If a node is visited and is already in the recursion stack, then the graph is cyclic
If DFS traversal completes without finding a cycle, then the graph is acyclic
- Q3. You have a stream of bytes from which you can read one byte at a time. You only have enough space to store one byte. After processing those bytes, you have to return a random byte. Note: The probability of...
- Ans.
Return a random byte from a stream of bytes with equal probability.
Create a variable to store the count of bytes read
Create a variable to store the current random byte
For each byte read, generate a random number between 0 and the count of bytes read
If the random number is 0, store the current byte as the random byte
Return the random byte
- Q4. Find if a given Binary Tree is BST or not
- Ans.
Check if a binary tree is a binary search tree or not.
Traverse the tree in-order and check if the values are in ascending order.
For each node, check if its value is greater than the maximum value of its left subtree and less than the minimum value of its right subtree.
Use recursion to check if all nodes in the tree satisfy the above condition.
- Q5. Devise an algorithm to determine the Nth-to-Last element in a singly linked list of unknown length. If N = 0, then your algorithm must return the last element. You should parse the list only once
- Ans.
Algorithm to find Nth-to-Last element in a singly linked list of unknown length
Traverse the list and maintain two pointers, one at the beginning and one at Nth node from beginning
Move both pointers simultaneously until the second pointer reaches the end of the list
The first pointer will be pointing to the Nth-to-Last element
If N=0, return the last element
Parse the list only once
- Q6. Given an array of integers, print all possible permutations. Also explain your approach
- Ans.
Print all possible permutations of an array of integers
Use recursion to swap elements and generate permutations
Start with the first element and swap it with each subsequent element
Repeat the process for the remaining elements
Stop when all elements have been swapped with the first element
Print each permutation as it is generated
- Q7. Design a Stack DS that also prints in O(1) the minimum element you pushed in the stack
- Ans.
Design a stack that prints the minimum element pushed in O(1)
Use two stacks, one for storing elements and another for storing minimums
When pushing an element, compare it with the top of minimum stack and push the smaller one
When popping an element, pop from both stacks
To get the minimum element, just return the top of minimum stack
- Q8. Given a linked list with loop, how would you find the starting point of the loop ?
- Ans.
To find the starting point of a loop in a linked list, use Floyd's cycle-finding algorithm.
Use two pointers, one moving at twice the speed of the other.
When they meet, move one pointer to the head of the list and keep the other at the meeting point.
Move both pointers one step at a time until they meet again, which is the starting point of the loop.
- Q9. Find a number a matrix mat[m][n] where all the rows and columns are sorted non-decreasingly. What will be the complexity of the solution
- Ans.
To find a number in a matrix where all rows and columns are sorted non-decreasingly. Complexity of the solution.
Use binary search to find the number in each row and column
Start from the top-right corner or bottom-left corner to optimize search
Time complexity: O(m log n) or O(n log m) depending on the starting corner
