http://www.anyforum.in/question/programming/basics/Program-to-help-the-king-to-save-the-kingdom/886
There are N cities in a kingdom. These cities are aligned in a row. So, each city has two neighbours except first and last city. Each city has an F-number which denotes the maximum cities he can ask for help in case of an attack. Each F-number lies between 1 to N. Two cities cannot have same F-number. The Power of a city c is the sum of F-numbers of the cities that c asked for help. In case of an attack, to save time, representative of the city will go to the first city he wants help from and ask the city to propogate the message to its right neighbour. Right neighbour will propagate the message to its right neighbour and so on. This process will stop when the attacked city gets the help form as many cities as it wants. It is obvious that a city will try to get maximum power. java program to find megaPrime number

http://www.anyforum.in/question/corejava/programming/WAP-to-check-an-ISBN-Number/819
An ISBN (International Standard Book Number) is a ten digit code which uniquely identifies a book. The first nine digits represent the Group, Publisher and Title of the book and the last digit is used to check whether ISBN is correct or not. Each of the first nine digits of the code can take a value between 0 and 9. Sometimes it is necessary to make the last digit equal to ten; this is done by writing the last digit of the code as X. To verify an ISBN, calculate 10 times the first digit, plus 9 times the second digit, plus 8 times the third and so on until we add 1 time the last digit. If the final number leaves no remainder when divided by 11, the code is a valid ISBN. Mystery Temple

Dinesh has been bullied enough all his life and now he seeks revenge. His first victim being Deepak, obviously! He found on e question to take revenge from deepak, but without knowing the answers of the question he would not be able to know whether deepak�s answers are correct or not. The question consists of two numbers, a and b, and the answer to it is the sum of digits of a^b (i.e - a raise to the power b). Help him to find the answers so that he can take revenge from deepak. (You should be able to write the solution for this problem in 25 minutes) Input: First line contains the number of test cases t. After that t lines follow each containing a pair of space separated integers i.e. a and b. Output: For each test case, you need to print the sum of digits in a^b. Sample Input : 2 2 10 3 3 Sample Output : 7 9 Explanation Consider the first test case. 2^10 = 1024 Now, 1 + 0 + 2 + 4 = 7 So, output for this test case is 7. Calculate loss and loss percentage
