3) CODE SKILLS - 15 Qusetions 40 Mins

2) GENERAL COMPUTER SCIENCE KNOWLEDGE

Some of them i remember are

1) Which of the following requries a recursive solution (or equavalent use of the stack).
A) Factorial function
B) Lookup in a sorted binary tree
1) JUST 1    2) JUST 2  3) BOTH   4) NEITHER

2) Decimal value of bitwise or of 96,48,24,8
A) 0    B) 64    C) 120    D) 176
not excatly the same but some thing of that sort

3) Program uses a stack to visit each of the nodes of a binary tree starting at its root after a node is visited its children are added to stack in what order do the node of the tree in the followin diag:

A-B,C (means A is the root and B, C are its children )
B-D,E
C-F,G
D-H,I
G-J
1) A B C D E F G H I J
2) A B D H I E C F G J
3) H I D E B F J G C A
4) H D I B E A F C J G

This question is there in data structures by Yaswanth Kanitkar.

4) Which is the regular expression matches string and only those strings that represent decimal numbers meeting the following R.E
1) .[0-9].[0-9]+
2) -?[0-9].0-9[0-9]
3) -?[0-9]*.[0-9]+
4)-?[0-9]*.0-9+

5) A Data Base trigger executes in resopnse to
DBMS QUESTION

6) A stored procedure in a DBMS is

7) PSUEDO CODE question :
find the output of the program

GLOBLAL N=0;
FUNCTION FOREACH(COL,F)
LOCAL N =20;
FOR EACH ELT IN COLL CO DO F(ELT)
FUNCTION FN1(COL);LOCAL N=30
FUNCTION FN2(NUMBER);
N=N+NUMBER
FOR EACH(COL,FN2);

{
NODE LEFT,RIGHT ;
}
What constructors should internal node have accordign to the specfication for the tree structures

Some thing that sort of questions
Like that there were 15 questions

THEY WERE EASY BUT VERY VERY VERY TRICKY

All what I want to say is if ur cool and 100% good at Data Structures, you can easily clear the code section in 40 min.
