Hallindrome

Given a string S. Let us divide 5 into two equal parts s1 and s2.s is called a halindrome if at least any one of the following conditions satisfy:

1.Sis a palindrome and length of S>=2

2.S1 is a halindrome.

3S2 a halindrome.

In the case of an odd length string the middle element is not present in both S1 and S2. If index of middle element is m. then, S1= S [0,m-1] and S2=S[m+1|S|-1].

Input Specification

input 1: Number of strings 1<=input1<=100.

imput2:An array of size input1 containing strings 2<=length of each string<=100.

output specification:

for each test case, return the number of strings which are halindromes.

EX:input1:1

input2:{harshk}

output 0

explanation:1.string S is not forming a palindrome.

2.string S1=har,which is not a halindrome.

3.String S2=shk,which is not a halindrome.

as none of the conditions are true,hence output to be returned is 0.

Zombie Apocalypse

A patient with first stage zombie virus has escaped from the facility in a city of population N. The zombie virus is very dangerous as it passer on to other people as they come in contact with the patient making them a patient as well.

Zombie virus has K life stages to develop, each of which takes 1 unit of time. Only the last stage is contagious. A person with zombie virus attacks only healthy people and can only affect one person in 1 unit of time.

if the patient escaped on Day 1. Find out the number of days it will take to wipe out the entire city's healthy population and turn them into a last stage zombie.

Note: 1 unit of time is equal to 1 day.

Input Specification.

Input1:Total healthy population of the city.

input2:Number of stages of zombie virus.

Output Specification

your function must return the numbers of days.

Example 1:

input1:10

input2:1

output:5

We want to calculate the total marks of each student of a class in Physics, Chemistry

and Mathematics and the average marks of the class. The number of students in the

class is entered by the user. Create a class named Marks with data members for roll

number, name and marks. Create three other classes inheriting the Marks class,

namely Physics, Chemistry and Mathematics, which are used to define marks in

individual subject of each student. Roll number of each student will be generated

automatically.

a) Write a CD class that extends the Item class. CD’s have a String artist field and an int playingTime field. This class should have appropriate constructors, getters and setters and should override the toString method and the depreciate method. CD’s depreciate by 10%. b) Write a DVD class that extends the Item class. The DVD class has a String director (the director of the movie) and an int runningTime (how long the movie is). Remember to provide the appropriate constructors, getters and setters and to override the toString method and the depreciate method. DVD’s depreciate by 15%

Write JSP programs which can perform the following tasks: (you may create a single or multiple web pages for these tasks): (i) A page requires input of three variables a, b, and c, it then finds and displays the largest of these three variables. Write the JSP code for the above. (ii) Create a login page for students which should create two cookies namely userID and password on successful login by a student.

The Super-class Write a class called Item. The Item class represents all that is common between various multimedia items. It should have the following attributes (fields): a) a String name to store the name of the item. b) a String comment to store a comment about the item. c) a double value to store how much the item cost. It should have appropriate constructors and at least the following methods a) getters and setters for the attributes. b) a public String toString() method that returns a String representation of the Item. c) a method void depreciate() that decreases the value of the item by 5%.
