  • 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...

  • 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.

  • 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...

  • 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.

  • 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.

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
