The total time to be spent on the Planning and the Examination Session is Three hours.
After completing the Planning Session, the candidate may begin with the Examination Session. A maximum of 90 minutes is permitted to begin the Examination Session.
However, if candidates finish earlier, they are to be permitted to begin the Examination Session.

The total time to be spent on the Planning and the Examination Session is Three hours.
After completing the Planning Session, the candidate may begin with the Examination Session.
A maximum of 90 minutes is permitted to begin the Examination Session.
However, if candidates finish earlier, they are to be permitted to begin the Examination Session.
——————————————————————————————————-

As it is a practical examination the candidate is expected to do the following:
1. Write an algorithm for the selected problem. [3]
(Algorithm should be expressed clearly using any standard scheme such as pseudo code or in steps which are simple enough to be obviously computable.)
2. Write a program in JAVA language. The program should follow the algorithm and should be logically and syntactically correct. [5]

3. Document the program using mnemonic names / comments, identifying and clearly describing the choice of data types and meaning of variables.
4. Code / Type the program on the computer and get a printout (hard copy). Typically this should be a program that compiles and runs correctly.
5. Test run the program on the computer using the given sample data and get a printout of the output in the format specified in the problem. [5]
6. Viva-Voce on the Selected Problem. [3]

Question 1
A palindrome is a word that may be read the same way in either direction. Accept a sentence in UPPER CASE which is terminated by either “.”, “?”, or “!”. Each word of the sentence is separated by a single blank space.
Perform the following taks:
(a) display the count of palindromic words in the sentence.
(b) Display the palindromic words in the sentence.

Example of palindromic words:
MADAM, ARORA, NOON
Test your program with the sample data and some random data:

Example 1
INPUT : MOM AND DAD ARE COMING AT NOON
OUTPUT : MOM DAD NOON
NUMBER OF PALINDROMIC WORDS : 3
Example 2
INPUT : HOW ARE YOU?
OUTPUT : NO PALINDROMIC WORDS

Question 2
Write a program to declare a square matrix A[][] of order (M X M) where ‘M’ is the number of rows and the number of columns such that M must be greater than 2 and less than 20. Allow the user to input integers into this matrix. Display appropriate error message for an invalid input. Perform the following tasks:
(a) Display the input matrix.
(b) Create a mirror image of the inputted matrix.
(c) Display the mirror image matrix.

Test your program for the following data and some random data:

Example 1
INPUT : M = 3

4 16 12
8 2 14
6 1 3
OUTPUT :

 ORIGINAL MATRIX

4 16 12
8 2 14
6 1 3

MIRROR IMAGE MATRIX

12 16 4
14 2 8
3 1 6
Example 2
INPUT : M = 22

OUTPUT : SIZE OUT OF RANGE

Question 3
A composite Magic number is a positive integer which is composite as well as a magic number. Composite number: A composite number is a number which has more than two factors. For example: 10 Factors are: 1,2,5,10 Magic number: A Magic number is a number in which the eventual sum of the digitd is equal to 1. For example: 28 = 2+8=10= 1+0=1 Accept two positive integers m and n, where m is less than n as user input. Display the number of composite magic integers that are in the range between m and n (both inclusive) and output them along with frequency, in the format specified below:

Example:
Input: m=10
n=100
OUTPUT:
The composite magic numbers are 10,28,46,55,64,82,91,100
Frequency of composite magic numbers: 8

Input: m=120
n=90
OUTPUT:
Invalid input
