How would you design Hospital management system ?

There are M chocolate packets each packet can have variable number of chocolates in each packet. There are N students (N < M). Distribute chocolate packets to student such that
a) each student gets 1 packet
b) suppose m1,m2,…mn are the packets which are chosen to be distributed in sorted order of number of chocolates in them (nm-n1 must be minimum)
M = 1, 3, 4, 6 (4 packets with specified number of chocolates in them)
N = 2
Ans = 3,4

Assume you have a starting 4 digit number, say 1234 and and ending 4 digit number 4567. For changing a bit of a number from 1 to 3 (for example), it will take 2 steps (from 1->2 and from 2->3). So to convert 1234 to 4567, you’ll have to change each and every bit individually in some number of steps. (Change 1->4 in 3 steps, 2->5 in 3 steps and so on). Now there is a list of blacklisted numbers. So while transforming start to end, if you reach a blacklisted number, then you cannot change that particular bit, you’ll have to move to another bit. E.g. Assume 1434 is a blacklisted number, and while transforming you reach it, then you have to change either 1, or 3 or the last 4. So you have to find the least number of steps in which start number can be transformed to end number.

I was asked to design a snake and ladder game. The game can have more obstacles than just snake and ladders.

There is a n player game of cards. The deck of card is not fair, i.e. any card can be there any number of times. A card has a number and a color. Each player gets k card each (n and k can be harcoded in the solution). The computer starts the game by throwing a card from the deck of cards. Assume the card is 4 of Green. Then the other player has to throw either a 4 of any color or Green of any number. If the player does not have any such card, then it can say pass. The player who finishes all his card wins. The logic of selecting the card by the user can be hardcoded (Eg, If you use a list data structure for storing the cards for a player, then you can say that the player always throws the first card from the list). The logic was required only to start and conclude the game.

Two players, two field; and have multiple ships located in their fields. They are guessing each others ship position and hitting. Tell who wins first. Design maintainable code which can incorporate future change.

Design a cricket series. Extend it to olympics.

Design and build tic tac toe game. The code should be up and running. It should be scalable to multi-users and nXn grid.

Print the bottom view of the binary tree.
Example :


1
/ \
/ \
2 3
/ \ / \
4 5 6 7
/ \ / \
8 9 10 11
/
12

Output should be :
8 12 9 10 5 6 11 7

Solution is different from http://www.geeksforgeeks.org/bottom-view-binary-tree/

Given an array and a target number. you have to print all sequences that generates the target number.
you can use two arithmetic operators '+' and '-' to perform operations among array elements.

Note: you can't modify the array and you have to use all the elments of the array. and the order would be same as given in the array.

Example : 1 9 1 2 , Target Number = 9

1 + 9 +1 -2 =9

output should be "1 + 9 +1 -2 "

You are given a catalog of books, which have following attributes :-
Name, Author, Publisher, Publish year, Category, Price, Count (sold)

Implement following APIs on top of this catalog -

1) addBookToCatalog(Book)
2) searchBook(by partial book name/author)
3) getMostSoldBooks(by author name/category, limit)

Expectations:
Maintain DB on memory

Code should be readable. Design, handle naming convention,handle exceptions & should be running

You have to compress a string in the following format.
eg 1- : input : aasasatb
output : 2a2sa1t1b
eg2 -: input: abcdbcdff
output :- 1a2bcd2f

design snakes and ladders game(multiplayer). extend it so that it can be hosted overs a server and played over a server

a) add a book
b) issue a book
c) return a book
d) if a user has kept a book more than 10 days then there should be a fine of Rs. 1 per day post 10 days.

given daily stock rates of last year give the average stock rate price for a given day range

given n-ary tree. zigzag level order traversal.

given unsorted array and a number K. Find 2 numbers such that sum is K

there are M chocolate packets each packet can have variable number of chocolates in each packet.
There are N students (N<M).
Distribute chocolate packets to student such that
1) each student gets 1 packet
2) suppose m1,m2,...mn are the packets which are chosen to be distributed in sorted order of number of chocolates in them (nm-n1 must be minimum)
M = 1, 3, 4, 6 (4 packets with specified number of chocolates in them)
N = 2

You have an organizational structure, which shows hierarchy of the organization. This hierarchy contains employees E or managers M who has some Employees or Managers reporting to M. Employee has ( id, name, JobDesc, salary etc). Design the data structure you would be using to store this hierarchy

1: Given an ID of an employee , print all the employee ID's who are directly reporting or indirectly reporting to the manager.
2. Given a bonus and performance rating of each employee divide it to the lowest level employees(in the hierarchy ) in the ratio of their rating. i.e 100 divided among 2:3 is 40 and 60. and print the bonus of each
3. Top 10 employees with ratio of bonus:salary

Note :-
1) Employee can have only 1 mgr, and a mgr has 1+ employees.
2) Input can be in any order for ex- employees might be input before his manager.

Assume a Game where a player can jump from one step to other to reach the final step.

From any given step Player can go to another step in any direction North, South, East or West. (i.e ) from Any given step user has a choice of multiple steps to choose from to proceed towards final step.
Some steps may not lead you in right direction to final step, in that case he need to retrace back.

To jump from one step to another Player uses a ladder. Distance between adjacent steps is not constant, they differ for each pair.

What is longest length of a ladder needed for the player to reach the final step from the starting step.

Implement a MessageBroker which accept messages from Publisher and deliver to Subscriber.

To begin with start with single Publisher and Subscriber. But design it in such a way to scale up to many publisher and subscriber associated with a Single Broker.

Take Performance and parallel processing into consideration.

#include <stdio.h>

int main()
{
printf(&unix["\0c%set\012"],(unix)["chak"]+"Trick"-0x67);
}

Design and Implement a Telephone database structure in which a Customer Entry has PhoneNum,Name,Address.

a) Given any PhoneNum return all the Customer details
b) Given any Name list all the Entries (As Name can be duplicate, only PhoneNum is unique)
c) Also Name searching should support Prefix Based.

Design Maps: You have set of [lat, long] for all famous locations. Given your position [lat, long] return all famous locations within r radius of your position.

You have set of [lat, long] of all famous locations. Given your position [lat, long] return all famous locations within radius r of your position

Consider the following class definition:
class Node {
List<Node> children;
void addChild (Node child);
}

Assume you have a node object like above. This node object can contain a child node object. Assuming you are given one of these objects, write a function to determine the maximum path length from the root node to the most distant remote node. .

Machine Coding:
Design and code application similar to IPL website.
1. There are players who belong different teams [CSK, RCB,etc].
2. User can create their own team from the player set
3. When a match happens, there are possible outcome in each ball [one run, six, wicket, run-out, etc]
4. on each outcome, players involved will get points [eg: six = batsman 5 points, wicket = batsman minus 5 and bowler +5, etc]
5. Based on outcome, the user created team also should be able to calculate his points.
6. Solution should be working code, extensible and performance.
