- Q1. Array sorting – Bubble sort and its complexity?
- Ans.
Bubble sort is a simple sorting algorithm that repeatedly steps through the list, compares adjacent elements and swaps them if they are in the wrong order.
Bubble sort has a worst-case and average complexity of O(n^2), where n is the number of items being sorted.
It is not efficient for large lists and is generally used for educational purposes.
Example: Sorting an array of strings in alphabetical order using bubble sort.

Interview Preparation Tips
Experience: The written test had 75 questions and we were allotted 80 minutes for the same.There were four sections: Verbal, Analytical, Attention to Detail and Technical (C and Data Structures).First, there was the verbal section. Basically, questions on articles, synonyms and antonyms were asked. Two passages were also given and related questions were asked. The analytical section included questions from quant (set theory, data sufficiency, cubes,etc.) and Logical Reasoning.
The third section was the easiest and did not require any special preparation. From a group of patterns, we had to determine if they were alike or different.
The fourth was the technical section and had 5 questions each from C and DS. This was the toughest section.Time management is absolutely important. There were sectional cutoffs and so we had to clear each section.
Round: Technical Interview
Experience: It was the PI round. First, we had the technical interview. Various questions on C and Data Structures were asked.Next, we had the HR interview. Here, the usual questions were asked. Some of them were:

- Q1. All project related questions .(He found some fault and asked to remove it)?
- Q2. Why do we need garbage collection and how it is done in JAVA ?
- Ans.
Garbage collection is necessary to free up memory occupied by unused objects. Java uses automatic garbage collection.
Garbage collection helps prevent memory leaks and improves performance.
Java uses a mark-and-sweep algorithm to identify and remove unused objects.
The JVM periodically checks for unused objects and frees up memory occupied by them.
Developers can also manually trigger garbage collection using System.gc() m...
- Q3. Difference between TCP and UDP ?
- Ans.
TCP is a connection-oriented protocol while UDP is connectionless.
TCP provides reliable data transfer while UDP does not guarantee reliability.
TCP uses flow control and congestion control while UDP does not.
TCP is slower than UDP due to the overhead of establishing and maintaining a connection.
UDP is faster than TCP for applications that can tolerate data loss such as video streaming or online gaming.
- Q4. In which scenario do we need UDP ?
- Ans.
UDP is used in scenarios where speed is more important than reliability, such as online gaming and video streaming.
UDP is a connectionless protocol that does not guarantee delivery of packets
It is faster than TCP because it does not have to establish a connection before sending data
UDP is commonly used in online gaming, video streaming, and VoIP applications
It is also used for broadcasting and multicasting data to mult

- Q6. Two puzzles a. Given a bar , cut it twice and pay for 7 days?
- Q7. B. three ants are running on edges of a equilateral triangle with same speed. What is prob that dey will never meet?
- Ans.
The probability that three ants running on the edges of an equilateral triangle will never meet is 1/3.
The ants will never meet if they all move in the same direction (clockwise or counterclockwise) at the same speed.
The probability of this happening is 1/3, as each ant has two possible directions to choose from.
Example: If one ant starts moving clockwise, the other two ants must also move clockwise to never meet.

- Ans.
STL knowledge and finding loop in linked list
STL (Standard Template Library) is a C++ library that provides containers, algorithms, and iterators.
To find a loop in a linked list, we can use Floyd's cycle-finding algorithm.
In this algorithm, we use two pointers, one moving at a slower pace and the other at a faster pace.
If there is a loop in the linked list, the faster pointer will eventually catch up to the slower poin...
