Synopsis Paper


1. The grammer for A, B, S is given below.


S->Ax|By
A->Ax|y
B->x|y
possible ans is xy|xy


2. In n*n matrix , there non zero numbers in diagonal and either side
of the diagonal. If represented in one dimensional array, assign the
values which are non zeros.
find relation with i,j iteration and linear arry
like a[2*(i-1)+j] this
3. In-order of the letters is given as below:If written in pre-order like given below: write the post-order:


4. fun(n)
{
if(n<=2)
return (1);
else
return ((fun(n-1)*fun(n-2));
}

find the order of complexity of the programme.

possible answer ---- N(2^n)


5.



6. If a and b are given. write the results of the programme
given below.

a=a XOR b;
b=a XOR b;
a= a XOR b;


answer is swaping of a and b so b,a is answer


7.

8.for a given CMOS the voltage is halved freqency doubled capacitance halved what is the present CMOS power


ans (b)---- dynamic power is 1/2 *C*f*V^2


9.if a row daminated two dimentional arry in the following which one is advantage
and why?

a) for(i=0;i<1000;i++)
for(j=0;j<1000;j++)
temp=temp+a[i][j];


b) for(j=0;j<1000;j++)
for(i=0;i<1000;i++)
temp=temp+a[i][j]


I donot know ans




10. what is area of a Hexagon with side as 1unit


ans is 3*(sqrt(3))/2

11. If traverse in a chess board right and down from one corner to another corner how many possible ways will be there



ans is C(16,8) or (16!/(8!*8!))


12. Tick the below which can biparate (graph theory)

1)tree 2)forest of trees 3) evencycle graph 4) oddcycle graph


ans is 1,2,3

13.The fig shown in below is a SRAM (1K* 4 bits) ,how many of this SRAMS are reqired to design 16K of one byte


ans is 32 SRAMS and one 4 to 16 decoder


14. suppose two persons entering into one room in the morning 5 to 6 A.M. what is the probability they will enter in 10 minits gap.

I donot know this answer

15. In a binary tree what is the hight and lowest no of levels for N nodes.


ans is highest is N and lowest is log(N+1) base 2


16.represent 3 and -3 in base -2 form taking two states (0,1) only


OTHER 5 QUESTIONS FROM SORTING TECHNICS SO PLEASE GO THROUGH SORTING TECHNICS .
