*********************
Some more Questions
*********************
here r some questions i remembered from ittiam test
(the questions r not exact but may give u some idea):-
comp sci section...
          *>how many binary search trees r there for which postorder and
inorder travrsals r same?
          *>for a microprocessor, some address pins r given...u have 2
find the addressing capability?
          *>numbers 1 to 9 (not in that order) given, u have to find root
if they r inserted in a bin search tree?
          *>implementation of x-or gate using combination of or,and and
not gates?
          *>2 men sit adjacent to each other in a circular queue of n
people.how many combinations possible?ANS:2/(n-1).
          *>Z-transform of impulse function.
          *>Laplace transform of pulse.
          *>for AND gate, one input has freq F,other has 2F,what will b
o/p freq?
          *>two c prog given of fib series.ANS:same o/p
          *>a few more questions on c prog

i remember 2 passages-they were picked straight from BARRON's:
          *>allan,parker,white,black,braun etc. sitting arrangement:
3-4questions
          *>a,b,c,d,e interview combinations, c can give only 1 int, all
others 2,

JUNO ONLINE SERVICES VISITED IITK ON 10TH AUG, the written test
consists of 3
sections. aptitude, c skill_set, and the last section one algorithm. i
have
listed the sections in reverse order..

  in the interview they asked some C funda, Kernighan & Ritche will 
help. also
some Communication Networks related questions for EE guys..
 

section C:

  sometimes in cryptography when using RSA algorithm, it is required to

store 'big integers'(more than alloted space for integers), suggest a

suitable method by which big integers can be stored , also device an

algorithm for adding of such numbers..

section B:

(Q) i=j=0;
       k=l=1;
       i=( j==(k=0));
      printf("%d%d%d",i,j,k);
    
      what is the 0/p ?
              Ans:  1    0     0

(Q)  x=printf("%d",x=22);
      what is the value of x ?
        Ans:  x value become 2 , because it returns the number of

character it printed.

(Q) some struct..

    *str++ -> P  (p is a pointer)
          there was some structure i didn't remined it.
    Q: it points what?
       Ans:  it points to pointer and then increments str.

(Q)int a=b=10;
     main( )
      {
      int a=15;

      b++;
      }
   printf("%d%d",a,b);
what is the output.
Ans:   a=10
             b=11

(Q) printf("%d%f",10,10);

`      Ans: misbehaviour of output because  corresponding to %d ,10

will get print, but corres. to %f ,10 will not get print because it is

int and there may be either a garbage value or any statement.

(Q) # define  HELLO  "world";
        char *s= "HELLO" ;
        printf("%s",s)
 
          what is the output?
           Ans:  HELLO

    { extern i=2;
      do{ 
          auto int i=4;
          printf("%d",i);
          }while(i--);

       printf("%d",i);
     }

    what will be printed?

    Ans. 444-1

  (Q)
      some function and three variables r given f1,f2,f3

      ans .. 3581321 (fibonacci sequence)

  (Q)
       given 4 functions which implements string length..

       find the correct form.. ans (b).

  (q).

       two for loops given,
 
          for(i=0;i<n;i++)

          for(i=0;i<n;++i)

        ans. both r same...


   (q)
          union
          { int a;
            float b;
          }z;

          z.a=2;
          z.b=12.0;
          printf("%d %f",z.a,z.b);

          what will be printed?

          ans.. garbage value, 12
          

  Section A:

(q).out of 52 well shuffled cards if 4 cards r taken one after the

other what is the    probability of all cards belong to the same suit.

(Q).second derivative of log(sinx)w.r.t. x

(Q).if two persons have a probability of death witjin 1 year of p,q

respectively.what is the probability that only one will be alive at the

end of the year?

(Q) max sinx(1+cosx))=?

(Q) .two lines of a ||gram r 2i+4j-5k and 2i+2j+3k then what is the

unit vector ||to the diagonal vector.

some simple problems on probabailty, simple trigonometry, on work

done(like A can do a piece of work in n days.., B.., A and B..), i'll

there were 2 sections 1.Technical 2.Aptitude

technical was a bit difficult than apti.

in technical there were mainly questions on Datastructures, OS and
Networks.

networks questions were mainly from datalink layer and network layer.

DS questions were on linkedlists,binary trees and hashing.

OS questions were on paging and schduling.

in apti they have asked to arrange sentences in order, questions based
on passage and some direct
apti.

some ques i have in mind are, i am giving answers after the question
itself:

1. what is the size of IPv6 ---16 bytes

2.how many possible trees are there such that both preorder and
postorder traversal are same if there
are n nodes in a binary tree ---0

3. four ques were given on error detection and control, like CRC
code,hamming code etc..

4.which protocol is used to convert the ethernet address to IP address
--- RARP

5.which is undeterminnistic network structure among 802.3,802.4,802.5
--802.4

6. some nodes were given and they are inserted into a binary search
tree, which is the root --- 8

7. which of the two codes executes fast

     for(i=0;i<100;i++)
        for(j=0;i<100;j++)
            a[i][j]=0;

    for(i=0;i<100;i++)
        for(j=0;j<100;j++)
            a[j][i]=0

  ans: first code

8. int j=3;
     int *p=&j;
    printf("%d %d", *p++,++*p);

   it will not increment j value as ++ is done first on p before *, so
address gets incremented and
garbage value will be there.

9. two questions were asked on doubly linked lists, for deleting a node
like given some piece of code
which is correct.

10. a question on interrupts in OS, what happens when a higher priority
process requests the CPU
when it is servicing a lower priority process.

11. a question on quick sort, given some   numbers what happens after
the first iteration.

if(j<=4)
{
a[i]=a[j]*a[j];
printf("%d",a[i]);
}
}

what is the o/p

6)2-3 very very easy c++ questions.


APTI:(For apti go through rs agarwal)
1) two questions on time discount and interest and
stuff like
that.(questions from rs agarwal only)
2)two hands of watch meet every 64 min. does the watch
go slow or
fast.
3)two pipes can  fill a tank in 4&5 hrs
respectively.one can empty in
2 hrs .If the tanks are opened in order 1,2,3 .m
respectively ,when
the cistern will be empty.
options--3p.m,4p.m,5p.m,6a.m,7a.m
Ans)5p.m

of 15 days a
reinforcement of men arrive and it is found that now
the provision
will last for 20 days more.Find the no. of men arrived

Ans)1900(check inrs agarwal).
5)one question from alligation and mixture(r.s
agarwal).
6) two or three questions at least had 5-7 steps given
for a
procedure ,the steps had to be arranged in alogical
oredr.There was a
simple catch in each but was easy.
e.g. to print ur name in reverse
1)print the 'i'th alphabet
2)count the no. of alphabets
3)If i=0 end
4)i--
5)goto 3
options like
a)3,2,4,5,1
b)2,1,4,5,3
c)1,4,2,3,5
d)none

-similar questions for calcuylating average,checking
greater etc.
-there was one flow chart of fibinacci series.
-loop for fibonacci.
-some simple C loops written in words to be traced
basically just
watch out for the catch.
i=j
k=(z+i)/(z+j)
l=3*i(j*3)
m=(3*(3+i)/(j*(3+j)
if i=3=j initially
a)all are same
b)one is different
c)all are different
d)none

7)Some simple computer based questions(objective)
-function of CPU
-what is ram etc.
-what is buffer.

8) some vague Data base questions (nobody understood
that)

For questions 6-10, read the passage and answer the
questions that follow:


      At a time when impressive breakthroughs in
technology are providing new and better products and
services, when improved communications are
transforming thw world into a global village, and when
democracies are sprouting in former communist lands,
we are simultaneously witnessing events that makie us
questioin whether so much progress is indeed
"progress".
      For example, we see reports of widespread
bribery by Italina and Japanese government officials,
exorbitant salaries for executives in North America,
extensive environmental pollution in eastern Europe,
and other instances of immoral or morally questionable
conduct in our organizations. In many otherwise
prospeous and afluent cities, we see an increase in
the numbers of homeless people. Even those who are
fortunate enough to have a job find that work is not
only not an opportunity for growth, but a source of
anxiety and insecurity.
      In the popular media as well as in academic
journals, we see great interest in the proposition
that business and other organizations leaders need to
become more responsible not just ot their stock
jolders but also to other stake holders- consumers,
employees, suppliers,government, and locla communites.
       Put simply, the quality of life and perhaps the
survivial of society depend on the moral caliber of
its members. This moral caliber, however, is largely
determined by people in leadership positions. The way
leaders function in their positions of influence
directly contributes to strengthening pr weakening the
moral fiber or society. The lives of Buddha, Mohammed,
Lao-Tzu, Gandhi and Socrates attest to their salutary
influence in their own way as well as for all time.
       A human being functions not just through the
physical body but also through the use of the
intellect and the will. The intellect penetrates those
deep levels of reality that are spiritual in nature
but that the physical senses and processes cannot
access. It does this through abstract concepts and
ideas that help to make sense of and give meaning to
the acts in the light of spiritual knowledge. It helps
us to make moral choices in living a spiritually
guided life.
      How do we describe the concept of spirituality
and its place in that domain? Spirituality is
difficult to define in a manner that is universally
acceptablke because religious beliefs and rites differ
widely age to age and from one society to another.
However, if we analyze the spiritual experience per se
and its behavioral manifestations among individuals of
different religious backgrounds, there is much accord
on the understanding and appreciation of the essence
of spirit at three levels: cognitive, affective, and
outward behavior.
      At a cognitive level,spiritual experience
represents a realization that,a t the core of human
existence, there is set of virtues and vices. Virtues
- prudence, justice, fortitude, and temperance- are
good habits that enable us to stirve toward relizng
our full potential. Ideally, the goal of human life is
to live these values and overcome the vices.
     At an affective or emotional level, the spiritual
experience represents a complete trust and dependence
on such virtues. In its most sublime, the spiritual
experience represents a complete identification with
these values,or with an individual embodying these
values, tha aim being to achieve some forme of
enduring blissful state of existence.
     How is the spiritual experience expressed in
outward behavior? What are the sources of the norms
andd principles within the spiritual domain? Response
to such questions generally come from prescriptions of
moral observance of the laws. It is not a question of
an act being legal or illegal, but whether the act is
good or evil. A morally good act is necessarily an
expression of a spirtual act.
     The ability to distinguish between morally good
and evil acts is critical to the formation of
character. Knowing ehtical principles alone is of
little value unless we make an effort to habitually
incorporate these principles in our behaviour.
     In the final analysis, the reward of the
spiritual experience is that it enables each

SECTION III - ANALYSIS PROGRAM SEGMENTS
---------------------------------------

1) Here is the structure declaration of a doubly
linked list

struct dlink {
int nodeid;
struct dlink *next;
struct dlink *prev;
} dlink_t;

A pointer of the head of the linked list is maintained
as a global variable,
whose definition is
dlink_t *head;

The funtion remove_element(dlink_t *rp), needs to
remove the node pointed to
the rp and adjust the head.

The first node's prev and the last node's next are
NULL.

remove_element(dlink_t *rp)
{
rp->prev->next = rp->next;
rp->next->prev = rp->prev;
if( head == rp)
head = rp->next;

Which of the following statement is true about the
function remove_element

A) It work when head is the same as rp
B) It does not work when rp is the last element on the
list
c) It sets the head of the list correctly
D) It works in all cases

Answer :B

2) Consider the following function written in c:

#define NULL 0

char *
index(sp,c)
register char *sp,c;
{
do {
if(*sp == c)
return (sp);
} while (*sp++);
return NULL;
}

The first argument sp, is a pointer to a C string. The
second
argument, c, is a character. This function scarches
for the character
c, in the string. If it is found a pointer to that
location is returned
else NULL is returned.
This function works
a) Always
b) Always, but fails when the first byte contais the
character c
c) works when c is a non NULL character only
d) Works only when the character c is found in the
string
answer: a

03) What is printed when this program is executed

happens when the
following code is executed.
main()
{
int x=0,*p=0;
x++; p++;
printf ("%d and %d\n",x,p);
}

a) 1 and 1 is printed
b) 1 and 4 is printed
c) 4 and 4 is printed

journey in two
travelling parties. For security, each travelling
party consists
of at least two knights. The two parties travel by
separate routes,
northern and southern. After one month, the routes of
the northern
and southern groups converge for a brief time and at
that point the
knights can, if they wish, rearrange their travelling
parties before
continuing, again in two parties along separate
northern and southern
routes. Throughout the entire trip, the composition of
travelling
parties must be in accord with the following
conditions
