ISC Computer Science Practical Exam-2013 solve

First of  all I want to say that the standard of  Question of Class XII computer Science is  gradually decreasing. 
In 2013 the computer Science practical question is class 9th  standard. All of my students completed it in half an hour (where total time is 3 hours).

Now  I am giving you the Hints  to solve the ISC-2013 practical papers.
Question no.-1:  In this question you just copy each digit as you did it in class IX reverse numbering program  and multiply each digit by a predefined variable (with initial value 10 and gradually decreasing by 1) and then divide it by 11 if remainder is zero then print "valid number".

Question no.-2: This is nothing but a matrix order printing of a 2D array. You just reverse the 2nd loop and print it in matrix order.

Question no.-3: Input any sentences and separate each word by using StringTokenizer class with delimeters
given in the question(?. ! etc.) and check the palindromic word.

Try it ......... if problem contact with me.
