  • Q1. -----/ But here the main thing is that handling of corner cases like when there are duplicate tickets and when there is no proper path possible with given tickets
  • Q2. N queen problem with problem statement and dry running of code with 4 queens and then writing the code
  • Ans. 

    N queen problem is to place N queens on an NxN chessboard without any two queens threatening each other.

    • The problem can be solved using backtracking algorithm

    • Start with placing a queen in the first row and move to the next row

    • If no safe position is found, backtrack to the previous row and try a different position

    • Repeat until all queens are placed or no safe position is found

    • Code can be written in any programming langua...

  • Q3. Sub set problem(Check if there exists any sub array with given sum in the array ) . But the thing here is that we have to do it with space complexity of only O( 1 K ) . K is the sum given .
  • Ans. 

    Check if there exists any sub array with given sum in the array with O(1K) space complexity.

    • Use two pointers to traverse the array and maintain a current sum.

    • If the current sum is greater than the given sum, move the left pointer.

    • If the current sum is less than the given sum, move the right pointer.

    • If the current sum is equal to the given sum, return true.

  • Answered by AI
  • Q4. What is NP hardness .
  • Ans. 

    NP hardness refers to the difficulty of solving a problem in non-deterministic polynomial time.

    • NP-hard problems are some of the most difficult problems in computer science.

    • They cannot be solved in polynomial time by any known algorithm.

    • Examples include the traveling salesman problem and the knapsack problem.

  • Answered by AI
  • Q5. What is the difference between references and pointers
  • Ans. 

    References and pointers are both used to access memory locations, but references cannot be null and cannot be reassigned.

    • Pointers can be null and can be reassigned to point to different memory locations.

    • References are automatically dereferenced, while pointers need to be explicitly dereferenced.

    • Pointers can perform arithmetic operations, while references cannot.

    • Example: int x = 5; int *ptr = &x; int &ref = x;

    • Example: i

  • Answered by AI
  • Q6. What is difference between reference variable and actual reference
  • Ans. 

    A reference variable is a variable that holds the memory address of an object, while an actual reference is the object itself.

    • A reference variable is declared with a specific type and can only refer to objects of that type.

    • An actual reference is the object itself, which can be accessed and manipulated using the reference variable.

    • Changing the value of a reference variable does not affect the original object, but changi...

  • Q8. Segmentation , virtual memory , paging
  • Q9. 0-1 Knapsack problem
  • Q10. What happens when we type an URL
  • Ans. 

    When we type an URL, the browser sends a request to the server hosting the website and retrieves the corresponding webpage.

    • The browser parses the URL to extract the protocol, domain, and path.

    • It resolves the domain name to an IP address using DNS.

    • The browser establishes a TCP connection with the server.

    • It sends an HTTP request to the server.

    • The server processes the request and sends back an HTTP response.

    • The browser re

  • Q11. Implementation of LRU (WIth Production level code)
  • Ans. 

    Implementation of LRU cache using a doubly linked list and a hash map.

    • LRU (Least Recently Used) cache is a data structure that stores a fixed number of items and evicts the least recently used item when the cache is full.

    • To implement LRU cache, we can use a doubly linked list to maintain the order of items based on their usage frequency.

    • We can also use a hash map to store the key-value pairs for quick access and retrie...

  • Q12. Given page access sequence and we have to tell final output using different page replacement algorithms like FIFO , LRU etc
  • Q13. What is indexing in DBMS How do we maintain it
  • Ans. 

    Indexing in DBMS is a technique to improve query performance by creating a data structure that allows faster data retrieval.

    • Indexing is used to speed up data retrieval operations in a database.

    • It involves creating a separate data structure that maps the values of a specific column to their corresponding records.

    • This data structure is called an index.

    • Indexes are typically created on columns that are frequently used in s...

  • Answered by AI
  • Q14. B trees , B+ trees with examples
  • Ans. 

    B trees and B+ trees are data structures used for efficient storage and retrieval of data in databases.

    • B trees are balanced trees with a variable number of child nodes per parent node. They are commonly used in databases to store large amounts of data.

    • B+ trees are a variant of B trees where all data is stored in the leaf nodes, and the internal nodes only contain keys. They are commonly used in databases for indexing.

  • Q15. AVL trees with examples and their balancing
  • Ans. 

    AVL trees are self-balancing binary search trees. They maintain a balance factor to ensure height balance.

    • AVL trees are named after their inventors, Adelson-Velsky and Landis.

    • They are height-balanced, meaning the difference in height between left and right subtrees is at most 1.

    • Insertion and deletion operations may cause imbalance, which is corrected by rotations.

    • AVL trees have a worst-case time complexity of O(log n) ...

  • Ans. 

    Given a list of process IDs and their corresponding parent process IDs, print the IDs of all processes that are children of a specific process ID, and recursively kill all their children.

    • Iterate through the list of process IDs and parent process IDs

    • Check if the current process ID is the one to be killed

    • If yes, recursively find and print all its children

    • If a child has further children, recursively kill them as well

Interview Preparation Tips

Round: WRITTEN
Experience: It is a written round .

We are given with 2 coding questions of 10 marks each .There is no negative marking for coding questions

1)Given a string you have to partition the string in such a manner that each part of the partitioned string is a palindrome in itself and you have to count the number of such partition

For eg: given string NITIN
N ITI N
N I T I N
NITIN
So output will be 3.

2)You are given with a large paragraph and N words.
You have to find a min length subparagraph of the paragraph which contain all those N words in any order. Here length of a paragraph is the count of words in the paragraph.

There are 20 MCQ's all are technical questions only majorly from DSA
Tips: Coding it comes from practice . And for aptitude be good at fundamentals like time complexities etc .

Round: Technical Interview
Experience: Some times luck in interview is also important .I was unable to solve the second question initially ,but later with the help of my interviewer I was able to solve it .
Tips: Even if you are not able to solve the question initially don't be panic it will definitely go well

Round: Technical Interview
Experience: There are so many other questions . But sorry to say that I don't remember all of them ,if I remember them at some other time I will again update it here .

This round interviewer was very nice person And he is very helpful in fact .
Tips: Have solid basics at all data structures and algorithms ,Operating Systems


Round: Technical Interview
Experience: This round is entirely about other CS subjects like OS , DBMS,Networking .

Here asked me do you know other CS subjects like compiler design etc .
But as I am from Electronics I told them that I don't know all those subjects
Tips: Be good at other Cs subjects also

Round: Technical Interview
Experience: I solved above question Using DFS .I constructed a Graph using given information . and I did DFS starting from Given process .In the graph I took each process as 1 Node and the corresponding parent child relationship between the process as edges .
Tips: They will give sufficient time for thinking of the solution . So don't worry immediately after seeing the question . First think well you will definitely get it

Skills: Algorithms And DataStructures, Algorithm Analysis, Operating Systems, Basic Knowledge Of DBMS, Networking Basics, Object Oriented Programming (OOP) Basics
