- Q1. Implement Merge Sort.

Divide the array into two halves
Recursively sort the two halves
Merge the sorted halves
- Q2. Given a BST containing distinct integers, and a number ‘X’, find all pairs of integers in the BST whose sum is equal to ‘X’.
- Ans.
Find pairs of integers in a BST whose sum is equal to a given number.
Traverse the BST and store the values in a hash set.
For each node, check if (X - node.value) exists in the hash set.
If yes, add the pair (node.value, X - node.value) to the result.
Continue traversal until all nodes are processed.
- Q3. Given a set of time intervals in any order, merge all overlapping intervals into one and output the result which should have only mutually exclusive intervals.
- Ans.
Merge overlapping time intervals into mutually exclusive intervals.
Sort the intervals based on their start time.
Iterate through the intervals and merge overlapping intervals.
Output the mutually exclusive intervals.
Example: [(1,3), (2,6), (8,10), (15,18)] -> [(1,6), (8,10), (15,18)]
- Q4. What are the different types of hashing? Suggest an alternative and a better way for Linear Chaining.
- Ans.
Different types of hashing and alternative for Linear Chaining
Different types of hashing include division, multiplication, and universal hashing
Alternative for Linear Chaining is Open Addressing

- Q5. Implement AVL Tree.
- Ans.
An AVL tree is a self-balancing binary search tree where the heights of the left and right subtrees differ by at most one.
AVL tree is a binary search tree with additional balance factor for each node.
The balance factor is the difference between the heights of the left and right subtrees.
Insertion and deletion operations in AVL tree maintain the balance factor to ensure the tree remains balanced.
Rotations are performed ...
- Q6. Minimum number of squares whose sum equals to given number n.
- Ans.
Find the minimum number of squares whose sum equals to a given number n.
Use dynamic programming to solve the problem efficiently.
Start with finding the square root of n and check if it is a perfect square.
If not, then try to find the minimum number of squares required for the remaining number.
Repeat the process until the remaining number becomes 0.
Return the minimum number of squares required for the given number n.
- Q7. Insertion sort for a singly linked list.
- Ans.
Insertion sort for a singly linked list.
Traverse the list and compare each node with the previous nodes
If the current node is smaller, swap it with the previous node
Repeat until the end of the list is reached
Time complexity is O(n^2)
Interview Preparation Tips
Experience: There were 2 coding questions (no penalty for wrong submission) and 20 Multiple Choice Questions(with negative marking). We were given 90 minutes to solve them. MCQs were based on Data Structures, OS, CN, C outputs, OOP etc.
Tips: Experience in Competitive Programming might help in solving coding questions. No constraints were mentioned and detailed Instructions related to problem were stated vaguely. So code carefully.
Duration: 1 hour 30 minutes
Total Questions: 22
Round: Technical Interview
Experience: The interviewer asked me to introduce myself and a brief introduction of the projects that I have done. She first asked me questions related to my project. After that she moved on to the data structures part.
Tips: Take your time to approach the problems and if the question is not clear ask the interviewer to explain it again.
Round: Technical Interview
Experience: The interviewer asked me about how my previous round went. After that, he asked me to introduce myself and a brief introduction of the projects that I have done. He first asked me a few questions related to my project. Then he moved on to the data structures part. In this round the interviewer gave me strict time limit for coding the solution on paper for each problem and as soon as I was done coding he gave me 2-3 minutes every time to find errors and debug my code.
Tips: Do not panic even if the interviewer sets time limit while solving problems. If the question is not clear ask the interviewer to explain it again.
