17. For an ambigous grammar, the compiler writer can either (approach 1) use a non-ambigous version of the same grammar, or (approach 2) retain the ambigous grammar, but resolve the ambiguity by introducing precedence and associative of operators. Why would he sometimes prefer approach 2 to approach 1? I. an ambigous grammar can produce at most two derivations II. ambiguous grammars being smaller, they result in shorter code III. ambigous grammars reduce parsing time by avoiding chain reduction

11. Policy 1: Allocate a file on disk contiguously Policy 2: Allocate a file on arbitrary blocks on disk Which of the following is/are the advantage of Policy 1: I. It is good for reading large files sequentially II. Files are easily expandable in this method III. Random access is faster in this method A. I B. I,III C. II D. III E. I,II,III

6. Which of the following does not help in writing programs for pipelined architectures: A. Unrolling short loops B. Writing short code segments with lot of subroutines C. Using registers as far as possible. D. Using direct/immediate modes of access E. Fixed-length integer instructions

Yah got it now I was having another kinda problem. Thanx.

7. 48 8. 2.22 9. 12.675 10. 35 11. 450 12. 1/6! and for the square question I think pavel is right. may b it was question no.3

unless there is told abt biasness we should consider fairness. As long as no additional information provided we can tell all of them has the equal probability to win.......1/n Dont know whether i m becoming more drowsy day by day.

Women's double tennis tournament. Men's double tennis tournament. I reckon the answer should be........... AP1 AP2 ------------------ BP1 BP2 14*12*10*8=13440 the answer comes out by filling the gaps. Yah people got attraction to other's wives. Besides we have to consider abt the people who may not be straight. hey dudes dont take me otherwise. hey . correct me if I am wrong. Pavel boss thik ase bondho. 32*24 = 768 is the answer pavel boss tor ta thiki ase. ami ektu matbori korlam. equation dekhlei matha ghure. 1-2-3-4-5 X-X-X-X-X X-X-X-X-X X-X-X-X-X X-X-X-X-X never include previous number element.Becaues there will be repetation in tat case. starting from row 1 . only element at row 1 are included here. here we can make up 5 rectangle including 1 [necessary condition to build rect] here we can make up 4 rectangle including 2 and excluding 1[necessary condition to build rect] here we can make up 3 rectangle including 3 and excluding 1,2[necessary condition to build rect] here we can make up 2 rectangle including 4 and excluding 1,2,3[necessary condition to build rect] here we can make up 1 rectangle including 5 and excluding 1,2,3,4[necessary condition to build rect] hence 15 rectangle down here apply this strategy to column now we will include and exclude a total row.Never go backwords. Becaues there will be repetation in tat case. 1-2-3-4-5 X-X-X-X-X X-X-X-X-X X-X-X-X-X X-X-X-X-X including row one and taking next rows we will get 5 case with 15 rectangle in each case never go backwords hence now discard row 1 take row 2 we taking next rows will get 4 case with 15 rect each row 3 ...............3 case 15 rect each row 4 ...............2 case 15 rect each row 5 ...............1 case 15 rect each15*15= hence result is 15*(1+2+3+4+5) = 225 long explanation. sorry dudes. 380 is the answer. Pavel correct, boss. pavel correct. r = 1/2 pavel correct. ans----A

what is the probability that K will not be an outcome either time? prob[K doesnt occur] = 1 -.4 = .6 prob[K doesnt occur in two time] = .6 * .6 = .36 its ok dude.
