Round 2 - One-on-one

(4 Questions)

Q1. What is a data structure?

Ans.

A data structure is a way of organizing and storing data in a computer so that it can be accessed and modified efficiently.

Data structures define the way data is stored, accessed, and manipulated in a computer program.
Examples include arrays, linked lists, stacks, queues, trees, and graphs.
Choosing the right data structure is crucial for optimizing the performance of algorithms and applications.

Q2. What is a linked list?

Ans.

A linked list is a data structure where each element is connected to the next element through pointers.

Consists of nodes where each node contains data and a reference to the next node
Can easily insert or delete elements without shifting other elements
Examples: singly linked list, doubly linked list, circular linked list

Q3. What is HashSet?

Ans.

HashSet is a collection that does not allow duplicate elements and does not guarantee the order of elements.

HashSet implements the Set interface in Java.
It uses a hash table for storage.
Example: HashSet set = new HashSet<>();

Q4. Explain recursion.

Ans.

Recursion is a programming technique where a function calls itself in order to solve a problem.

Recursion involves breaking down a problem into smaller subproblems and solving them recursively.
A base case is needed to stop the recursion and prevent infinite loops.
Recursion can be used to solve problems like factorial calculation, Fibonacci sequence, and tree traversal.

Q1. What is a static constructor?

Ans.

A static constructor is a special type of constructor in a class that is used to initialize static data members.

Static constructors are called only once when the class is first accessed.
They are used to initialize static variables or perform any necessary setup for the class.
Static constructors do not take any parameters and cannot be called explicitly.
Example: public class MyClass { static MyClass() { // initializatio

Ans.

The question is about finding the minimum steps to reach from a source string to a destination string using three operations.

BFS and DFS are graph traversal techniques that can be used to solve this problem.
BFS is typically used when finding the shortest path or exploring all possible paths in a graph.
DFS is useful when searching for a specific path or exploring deeply into a graph.
In this case, BFS can be used to find...

Interview Preparation Tips

Round: Test
Experience: • 1 question was on time complexity of searching an unsorted array.
• 2 questions were on recursion, ie, number of recursive calls.
• 1 question on analysing given function on string.
• 1 question was on probability(Two hotels, say A and B. Probability of moving from A to B is 2/3, staying at A is 1/3. Probability of moving from B to A and staying at B is 1/2. If they make decisions each hour, and if they were at A at 7:00 pm, what is the probability that they will be at B at 10:00 pm).
• If a set has elements {1,2,3,4 .... n}. Then what is the sum of elements of it's power set. (Ex: S = {1,2}. Then power set is {{},{1},{2},{1,2}}. The sum is 6.
• If a set has elements {1,2,3,4,5,6,7,8,9,10}. Then how many subsets of 3 elements has no consecutive elements.
• 1 question was on designing a DFA for a string starting with a and ending with c and has at least b in it.
• 1 question had machine instructions. We had to find out minimum number of cycles needed to execute the given set of instructions. (a) If the instructions are executed in the given order. (b) If the instructions are executed in random order.
• 1 puzzle on bridges.

Tips: In this round they not only see the answer. They also verify how you approached(So, give correct explanation to your answers).
Duration: 90 minutes
Total Questions: 10

Round: Coding Round
Experience: Two questions were there. 3 hours duration.

1. Long question, I don't remember fully. I'll just give input/output examples. It was basically on string decoding. If jon2snow3 is there the decoded string will be jonjonsnowjonjonsnowjonjonsnow. Given a string and an integer k we have print the kth character in the decoded string
input:
jon2snow3
8
output:
n

2. Given an array and an integer k return the number of contiguous sub arrays whose sum is divisible by k.
input format:
n k

input:
4 5
10 0 4 5

output:
4

explaination: {10},{0},{10,0},{5} are the sub arrays with sum divisible by 5.

Tips: You will have lots of time, so try to optimise the solution if you can. Remember here also they review each individual's code.

Round: Technical Interview
Experience: They will help you a lot if you are stuck at some point in the question. You have to be smart enough to grasp the clue.
Tips: They only ask questions only on data structures and algorithms.

Skill Tips: You have to be strong in coding. Algorithm questions will be mostly on dynamic programming. Data structures questions are mostly on trees.
Skills: C Programming, Maths(esp Probability), Algorithms And Data Structures
Duration: 5

Q1. Floor value of square root of a number

Ans.

Floor value of square root of a number is the largest integer less than or equal to the square root.

The floor value of square root of a number can be found using mathematical functions like floor() or integer division.
For example, the floor value of square root of 16 is 4, as sqrt(16) = 4.
For non-perfect square numbers, the floor value of square root can be calculated using approximation methods.
