Verifone (Test)


Verifone test Questions:
Two parts:
Note: Here are answers to what I have written, can not be right.

1. Aptitude test: 15 minutes, 20 questions
Eg. Product of three pieces. 210. What is the sum of at least two numbers?
Answer: 5 6 * 7 * = 210 funds, 11 answer =

Eg. Sqaure in an increase of 69% increase in the length of such a favor?
Answer: 13 (I think)

Eg. If the sum of the five pieces. 35? How many prime nos are:
Answer: 5 6 + 7 + 8 + 9 = 35, so the two primes

Eg. The length of the rectangle is reduced by 20% and 20% increase in respiratory What is the net change?
Answer: 4% decrease

2). Electrical and Electronics: 15 questions and, nand ... Circuit realted stuff ...
Data Structures, Algo, and complexity theory: 5 questions

A. If W is a sequence of strings without a and W is generated by its' Waw is reversed if:
ans. I think that context-free Grammmars

b. What could be the recusive pgm iteratively writtten?

c. What will you use data structes past and vice versa if you want to go to the first record?
Answer: circular doubly linked list

d. Given Nos. 10000. And 48MB memory. What is the complexity of efficient sorting algo? (Algo is not mentioned.)

E. Given a C code and ask what he does? I think the bubble sort and that particular code similar to the code in the order and sorting Desending complexity O (n ^ 2) (the next question).

3. OS: 5 Questions
A. If there are too many page faults what is the problem?

b. Ensure Pgm one. Not corrupt other pgm. A Multi-pgm. Environment, what should you do?

c. You - What would use to implement a critical section? Binary semaphore

d. Is not necessary for a Multi-pgm. Environment? Virtual memory, security, time interchange, none of the above options.

4. Networks and Hardware: 5 questions
A. Which is used by a data link layer? Stuffing bits, parity, LRC, CRC, Czech

b. Which is not related to the data link layer?

c. Which is not suitable for a client-server application? TCP / IP, message passing, RPC, none of the above.

5. Databases and miscellaneous: 5 Questions
A. What SQL .................. (Detail)

b. Indexing in databases give you ............

6. PGM C.: 5 Questions
1. int a = 1, b = 2, c = 3;
printf ("% d,% d", a, b, c);
Output?

2. For (i = 0; i <= 10; i + +, printf ("% d", i); + (+ - in questions)

3. Scope static variables ............

4. Given what the output is a C code?
