In my last blog I gave very brief description about my journey to different IIT's. In this blog I am going to tell you some of the questions which were asked in for IIT Madras MS 3 year programme.

Also, I will give some suggestions to this year students. Please feel free to ask for any suggestion.

In 2012 IIT Madras called upto 1000 Gate rank. It is a very good opportunity for high rankers, please do prepare for this exam if you got more than 400 rank. Here, I will post some of the questions, which will give rough idea and you can prepare accordingly.

There were 2 exams with no gap in between. Part A was 30 min test and Part B was 75 min test.

This was an easy part. Following are some of the questions:

**NOTE: This post is for CSE students. Other can ask for suggestions**In 2012 IIT Madras called upto 1000 Gate rank. It is a very good opportunity for high rankers, please do prepare for this exam if you got more than 400 rank. Here, I will post some of the questions, which will give rough idea and you can prepare accordingly.

There were 2 exams with no gap in between. Part A was 30 min test and Part B was 75 min test.

**Description of Part-A:**This was an easy part. Following are some of the questions:

**1-mark:**- Number of NAND gates required for XOR
- Output of C Program
main() { int c; printf("%d",scanf("%d",c)); }

**3-marks:**- Bus and auto question. To find when auto will reach..
- Ram and Shyam age question.
- Mango Question was like: If someone buys 1 mango then each mango cost is Rs. 50, if some one buys 10 mango then cost of each Mango is Rs. 5, if some one buys 100 Mango then price of each mango is 0.5 and the process continues. We were asked to find "How many we can buy in Rs. 50?" and "How many we can buy in Rs. 40?"
- 1 permutation question

**Description of Part-B:**

This was tough part and was subjective. Out of 9 questions you have to attempt for 5 questions. Following are some of the questions(Note all questions may not be correct as I have written on memory basis)

- i) Prove or dis-approve for a,b,c,d,e distinct natural numbers

1/a + 1/b + 1/c + 1/d + 1/e =7/3

ii) a,b,c,d are distinct natural numbers. (d-a),(b-c) are +ve numbers and (c-d),(a-c) are -ve numbers. Is it possible , give reasons - Let a,b,c,d are 4 consecutive numbers of Fibonacci series. Prove or dis-approve ad-bc= ±1
- There are 6 persons. Prove that there are 3 persons who know each other and other 3 don't know.
- Solve Recurrence Relation:

T(n) = T(nb/a) + T((n-b)c/a) +n

- To find total access time

L1 Cache hit Ratio 0.98 and access time 3 micro-sec

L2 Cahce hit Ratio 0.92 and access time 20 micro-sec

Main memory: 1000 micro sec

- Let a ∈(0,1,X). From this set-A and set-B are formed. A compatible set is a set in which either both contains 0 or 1 or X combination with 0 or 1. Find, if the above relation is equivalence or not
- Program Counter etc with some definition. Write assembly code for auto-increment and auto-decrement opcodes.
- An array contain numbers from 1 to n and is of size n. Find, if the array has any element that got repeated. Write code for it.(Hint: You can modify the array)
- You have mod-8 counter of frequency 500Hz . Change it to mod-3 counter of 250 Hz

If you crack written test, then there are 70-80% chances that interview will be cleared.

**NOTE: If you are not able to clear this exam, then don't get disappointed. You can also try for this in the winter session.(you get 2 chances a year for this)**

**Interview Experience:**

IIT Madras interview consisted of 5-6 professors in a room. Don't get panic. Here each professor is expert in his own subject or area. They will ask your favorite subject and the professor of only that subject will be interested to ask questions.

Firstly they will ask why are you opting for MS and they will try to find if you have any re-search interest. If your rank is below 300, then they may doubt that if you will join or not (Sometimes, students below 300 rank prefer for M.Tech)

Secondly they will give you a list of subjects and you can choose one of the subject.

I had chosen Data structures. Then they asked, my preferred topic in Data Structures.

*My Question:*Why quick sort is preferred over heap sort, even though quick sort worst case complexity is O(n^2) while for heap sort it is O(nlogn) for all cases.

They were trying to find my approach of solving the ans. I was unable to answer this question properly, though they selected me.

I am not posting the answer of interview question. If you don't get answer then feel free to ask.

There are 40 students who finally got selected out of 60 students who got shortlisted after written. There were around 300 students who appeared for written.

Please feel free to ask for suggestion. I will reply back your queries.

i also got call from IITM MS. plzz guide me also

Problem: If 6 persons are there , there are at least 3 persons who knows each other or 3 perfect strangers.

DeleteProof by case reduction.

Select a person x from group of 6,

Case 1: There are at least 3 persons x knows

Case 1a: In these three persons 2 knows each other. Now we have 3 persons who knows each other.

Case 1b: there are no pair who knows each other. This means we have three strangers.

Case 2: There are at least 3 unknown persons to x

Case 2a: there is a pair who doesn't know each other. we have three strangers.

Case 2b: every pair knows each other. we have three persons who knows each other.

ReplyDeleteqsort is preferred over heap sort becoz in heapsort we need call the heapyfy module everytime to adjust the heap after one swap so this calling a module is a overhead while in qsort the information is sorted in one module only and we just need to check the invariant . So qsort is faster

ReplyDeletehello sir....wanted to know what are the expectations for the cut off and highest rank to get admission in iisc,iit's and nit-warangal, surat and trichy for computer science SC candidate in gate 2014...pls update soon

ReplyDeleteThe answer to above question that why quick sort is preffered over heapsort is that because quick sort has a better locality of reference . it levrages the locality principle more because of the fact that the most data movements actually happens near the same region of array unlike in heapsort the hole array is kind of shuffled due to heapify procedure.

ReplyDeleteMoreover we can run quick sort in O(nlg n) by randomiztion. Pls correct me if you find anything incorrect.

Thanks
