6.

Considering a hash table with 100 slots. Collisions are resolved using chaining. Assuming simple uniform hashing, what is the probability that the first 3 slots are unfilled after the first 3 insertions? (NOTE:100 ^ 3 means 100 raised to the power 3) ?

The probability that the first 3 slots are unfilled after the first 3 insertions is 0.6712673.

The probability that the first 3 slots are unfilled after the first 3 insertions is 0.6712673.

27.12%

The probability that the first 3 slots are unfilled after the first 3 insertions is 0.412673.

The probability that the first 3 slots are unfilled after the first 3 insertions is 0.412673.

25.82%

The probability that the first 3 slots are unfilled after the first 3 insertions is 0.912673.

The probability that the first 3 slots are unfilled after the first 3 insertions is 0.912673.

32.03%

The probability that the first 3 slots are unfilled after the first 3 insertions is 0.922373.

15.03%

Answer :: (C)

EXPLANATION :

Step-by-step explanation:

 

Given : Considering a hash table with 100 slots. Collisions are resolved using chaining. Assuming simple uniform hashing.

 

To find : What is the probability that the first 3 slots are unfilled after the first 3 insertions?

Solution :

Each item hashed has an equal probability of being placed into a slot.

Probability that first item does not go in any of the first 3 slots is given by,

Probability that second item does not go in any of the first 3 slots is given by,

Probability that third item does not go in any of the first 3 slots is given by,

Probability that the first 3 slots are unfilled after the first 3 insertions is given by,

Therefore, The probability that the first 3 slots are unfilled after the first 3 insertions is 0.912673.

Good Job! Did you know? : With $8.5 billion in their kitty, Wipro is the 4th largest Indian IT company in terms of revenue.

Student Experience

TCS On-Campus Interview Experience

  • Name: Mayur Jain
  • College: IIT, Varanasi
  • Branch: Computer Science
  • Type of interview: ON-campus Interview

Student Interview

Tata Consultancy Service (TCS) conducted its pool campus drive in our college last year. Our training and placement officer asked us to assemble in the auditorium a few days prior to the interview process and gave us a brief overview of the company, its eligibility criteria, and interview process. The officer shared the link to apply for the interview. I started my preparation for the exam as soon as I received my exam details. I also started looking for previous questions to get an idea of how to get selected for the exam, and I came to know about the Prepinsta, my friend told me that they have the best preparation material, with a good set of sample previous years questions. I immediately bought the material online and started my preparation.

Eligibility Criteria

  • Full-time graduate from B.E/B.Tech/M.Tech./M.Sc./MCA
  • Eligible Stream: All engineering field
  • 60% marks throughout academics
  • 1 active backlog is acceptable
  • Overall academic gap does not exceed 2 years

Rounds

Our professor informed us that we have to complete three rounds to crack the interview. The rounds were:

  1. Online Written Test
  2. Technical Interview Round
  3. HR Interview Round

Online Written Test

The first round of TCS was made up of four sections. The first one among them was English, the second was quantitative aptitude and Logical Reasoning, third was a programming concept, and the fourth one was coding. This round was significantly easy for me, and about 70% of the questions were of similar pattern from PrepInsta’s study material .

Section No. of Questions Duration Question Types
English 24 30 minutes Questions based on Sentence Completion
Quantitative Aptitude and Logical Reasoning
 26 and 30
 40 and 50minutes
  • Time & work
  • Profit & Loss
  • Number, decimal fraction
  • Time, Speed & Distance
  • Geometry, coordinate geometry
  • Blood relations
  • Syllogism
Programming Concept 10 15 minutes
  • Iteration, recursion, procedural vs. OOp.
  • Algorithms
  • Data Structure
Coding 2 45 minutes
  • C/C++
  • Java
  • Perl
  • Python 2.7

Technical Interview Round

After the written test, I was selected for the face-to-face technical round. The interviewer who took my interview was the Senior Software Engineer of the company. The technical round included two interviews. The first was TCS Ninja and second, was TCS digital. The TCS Ninja interview lasted for 25 minutes, and questions asked to me were:

  • A brief interview about my last semester project and my role in it.
  • What is core C and C++?
  • What is polymorphism and explain Oops concept?
  • Where do I see myself in the next 3 years?
  • What are my strengths and weakness?
  • The second interview was with TCS Digital. It was the toughest and trickiest part of the selection process. A lady interviewed me and asked the same question about my last semester project. As soon as I mentioned “NoSQL” she asked me:
  • What is NoSQL?
  • Difference between NoSQL and RDBMS?
  • Write code for max sum subarray?
  • Then he asked me to solve ant and triangle puzzle problem.

HR Round

After the 2 interviews round the last was the HR interview. The final interview was taken by the HR of the company. She asked me what I know about the company and why I want to join it. She later asked for my resume and asked me to introduce myself. Then she asked me about my salary expectations and future plans. The interview went well, and I cleared my first interview with TCS.
