- Q1. Dijkastra's Algorithm
- Ans.
Dijkstra's Algorithm is a graph search algorithm that finds the shortest path between nodes in a graph.
Dijkstra's Algorithm is used to find the shortest path from a starting node to all other nodes in a weighted graph.
It works by maintaining a set of nodes whose shortest distance from the starting node is known.
The algorithm iteratively selects the node with the smallest distance and updates the distances of its neighb...

Round duration - 70 Minutes
Round difficulty - Medium
Interviewer was very nice and made me feel pretty comfortable. We talked about our hobbies for about 10mins and then he asked about my projects and which was my favourite of all. He then asked me a coding question. Which was like pretty easy and I gave him the optimized approach right away. He was satisfied with my approach and just moved on to the next part. He asked me some basic questions related to Operating Systems(related to deadlocks and semaphores). He even asked some basic questions related to OOPS. Then he gave me the next question. This was like a pretty new question for me and I took some time to understand the problem statement and then took some time to think about the logic. I was also sharing my approach with interviewer as well.I finally told him about my approach. He told me that my approach was fine but there also was some other approach but normally no-one would come up with that approach until they have previously solved the question.
- Q1.
Subtree Node Count Problem
We are provided with a tree containing 'N' nodes, numbered from 0 to N-1. The objective is to determine the total number of nodes within each subtree of the provided tree. Speci...
- Ans.
Given a tree, find the number of nodes in each subtree rooted at every node.
Traverse the tree using Depth First Search (DFS) to count nodes in each subtree.
Maintain a count of nodes in each subtree while traversing the tree.
Start the DFS from the root node (node 0) and recursively count nodes in each subtree.
For leaf nodes, the subtree size will be 1 (the node itself).

Interview Preparation Tips
Tip 1 : Try to code the data structures that you have learned to understand things better
Tip 2 : Try to solve the problem even if it is the worst possible solution you think and then try to optimize don't jump to get the
best possible solution
Tip 3 : Discuss things among peers it helps to improve the understanding, even try to teach someone anything new you learn, this is very helpful during the interviews as you will have habit of explaining things
Tip 1 : Try to be honest in the resume don't write something you don't know, most of the time it backfires.
Tip 2 : Try to make 2 good projects for cv and know about the challenges you can face on the project and think about how you can solve that challenge.

Interview Preparation Tips
Experience: I consulted my seniors for preparation of my resume. I believe that seniors provide the best possible insights in this regards. I had a standard resume for all the companies.
Round: Test
Experience: I had prepared for the CAT examination which helped me in these written tests. The first round was the written test. The criterion for the written test was to have a CGPA more than 6.0. There was an aptitude test and a technical test. The technical test consisted of programming questions based on C++ and data structures. From data structures they asked a lot questions based on tree traversals and from C++. A large number of questions from pointers and arrays were also asked.
The aptitude test was slightly easier than the CAT examination standards. Majority of the questions were related to data interpretation and some were of based on logical reasoning. The total duration of the both the tests combined was 90 minutes.
Around 50 people appeared for the first round and nearly 13 got shortlisted for the next round.
Tips: For the written tests, particularly the aptitude section, if would really help if you have prepared for the CAT examination. There is a book written by an author named R.S. Agarwal which would prove to be beneficial from the point of view of these written tests.
Duration: 90 minutes
Round: Group Discussion
Experience: I did not prepare much for the GD’s. However I did keep myself abreast with certain latest happenings.There were no group activities conducted in the recruitment process of Century Link.
Round: HR Interview
Experience: For HR interviews I prepared answers to some frequently asked HR questions. I found these questions on the internet. Generally the questions asked in the interviews are related to the profile on offer; for instance in A2Z interview I was asked a lot of questions from power systems since it was a core company and in Century Links I was asked questions from C++ and data structures since they had come to recruit for a software engineering profile.
Round: Technical Interview
Experience: In this interview I was questioned on my C++ and data structure knowledge. They asked me questions on pointers and further asked me to explain the concept of dangling pointers. They did not want me to write down the complete code with proper syntax's of the problems asked to me. They only asked me to write the algorithms of the various problems.
They also asked me some puzzles. Unfortunately, I was not able to solve any of them. During the course of the interview they asked me to specify the reason for my keen interest in joining an IT company.
At the end of first interview some candidates were shortlisted and called for the second round of interview.
Round: Technical Interview
Experience: The second interview was conducted by a senior company official. He enquired about my project and again, like in the first interview, asked me to state the reason for my interest in joining an IT company.This interview round was an elimination round.
Round: HR Interview
Experience: The interview was an HR interview. Candidates who reached till this interview were all selected; basically this interview was like a formality to check the candidate’s fit with the company.

- Q6. What is the difference between into arr [5] and malloc (5*sizeof (int))
- Ans.
The difference is that 'int arr[5]' creates an array on the stack, while 'malloc(5*sizeof(int))' allocates memory on the heap.
int arr[5] creates an array of 5 integers on the stack, which is a fixed-size memory allocation.
malloc(5*sizeof(int)) dynamically allocates memory on the heap, allowing for variable-size memory allocation.
The memory allocated with malloc must be explicitly freed with free() to avoid memory leaks
