A and B are 32 bit numbers with first 16 bits valid in A and next 16 bits valid in B. (The non-valid bits aren't necessarily 0). WAP that adds A and B without using arithmetic operator.

3 Answers

Mask the valid bits and make invalid bits 0. Then do A|B to get the ans

( A & 0xff00 ) | ( B & 0x00ff )

(A&0xffff0000) | (B&0x0000ffff)


They asked me just some basic questions for namesake- Like what do i do in my current company, what have I done in my previous job etc.

Dear Ms.Peters, I read your reply. Unfortunately I personally had a very different and a bad experience even though your statistics might suggest a different picture. Though I appreciate your efforts at replying back, unfortunately I am no more interested in any opportunities in Lahmeyer. Nevertheless, I wish you and the company all the best for future. Less

why is matching required?

2 Answers

Maximum power transfer.

Matching in MOSFET transistor inverters is necessary because the electrons that move in the NMOS transistor move at a faster rate than the holes that move in the PMOS transistor. This means when a signal is received, the NMOS will react before the PMOS. To equalize this, they transistors must be matched (by adjusting their widths) so that their transition times are the same.

If there was a lot of wind power coming in, and not very much load demand at that time, what would you do (right now) to reduce congestion on that transmission line?

2 Answers

-Decrease prices at the load source, encouraging people to buy -Increase prices for wind producers, encourage them to curtail power I was a bit confused at first because I didn't know if the region was variable rate or fixed rate pricing, so I clarified with the interviewer. Less

Could a potential answer here be to activate local demand response resources?


1)WAP to count the number of set bits where no of iterations must be equal to the number of set bits, irrespective of the total number of bits. Now make this number of iterations 1/8th. 2) WAP for ceiling function of 2 nos. eg: Ceiling(5/3) should return 3.

2 Answers

int r = n1 / n2 if(n1 % n2) r += 1

2) but ceiling (4/2) should return 2. take care of that case
