A call center agent has a list of 305 phone numbers of people in alphabetic order of names (but she does not have any of the names). She needs to quickly contact Deepak Sharma to convey a message to him. If each call takes 2 minutes to complete, and every call is answered, what is the minimum amount of time in which she can guarantee to deliver the message to Mr Sharma.

problems.
The Interviewer Candidate Problem
Refer to the diagram above. It is a walk-in-interview setup having an interview room with
one chair and a waiting room with a number of chairs. The interviewer interviews
candidates in the interview room. When the interviewer finishes interviewing a candidate,
he dismisses the candidate and goes to the waiting room to see if there are other
candidates waiting. If there are, he brings one of them to his room and interviews him. If
there are no candidates waiting, he returns to his chair in the interview room and
continues reading his last unfinished magazine. If there are no unfinished magazines, he
starts reading a new magazine. After he finishes reading one full magazine, he goes to
sleep.
Each candidate, when he arrives, looks to see what the interviewer is doing. If the
interviewer is reading a magazine, the candidate waits for the interviewer to finish
reading the current page of the magazine. Then the candidate enters the interview room
and asks the interviewer to interview him. If the interviewer is sleeping, the candidate
wakes him up and then asks the interviewer to interview him. If the interviewer is
interviewing another candidate, the candidate goes to the waiting room. If there is a free
chair in the waiting room, the candidate sits in it and waits his turn. If there is no free
chair, then the candidate leaves.
Based on a naive analysis, the above description should ensure that the walk-ininterview
functions correctly, with the interviewer interviewing any candidate who arrives
until there are no more candidates, and then reading magazines and/or sleeping until the
next candidate arrives. In practice, there are a number of problems that can occur that
are illustrative of general scheduling problems. Please discuss those problems and
provide an algorithm to solve those problems.
Note: There are two doors between the interview room and the waiting room.
Tip: Read literature on the Dining Philosophers problem
Satyaaki and Yudhistra’s problem
Imagine that two divisions of the Pandava army are camped outside an enemy camp of
Kauravas commanded by Bhishma. Each division is commanded by its own general;
Saatyaki and Yudhishtra. The two generals can communicate with one another only by
messengers, who might get caught by the Kauravas. After observing the Kaurava camp,
Saatyaki and Yudhistra must each decide independently whether to attack the Kauravas
or not. Then they must each communicate their plan to the other through messengers.
Upon receiving a message from the other, both Saatyaki and Yudhistra must decide a
common plan of action. The Pandavas can succeed only when both Saatyaki and
Yudhishtra attack the Kaurava camp at the same time.
Discuss the above problem in detail and provide a solution to the same.

Total money is double the money of C.

Missing number is 282.
Difference in two numbers are
2*1^2=2
3*2^2=12
4*3^2=36
5*4^2=80
6*5^2=150
7*6^2=252
Hence missing number is 132+150= 282

There are two series

In first case , difference between numbers are equal to successive even numbers and in second case, difference in numbers are square of successive odd numbers.
