[ vuZs.net ] idea solution of cs502

Use induction to prove that radix sort works. Where does your proof need the assumption that the intermediate sort is stable?
solution:
Basis: If $d = 1$ , sorting on that digit sorts the array correctly.
Inductive step: Assume that RADIX-SORT sorts $d-1$ digits correctly. Consider two elements $a$ and $b$ , with their $d$ th digit $a_d$ and $b_d$ respectively.
(1) $a_d > b_d$ and $b_d > a_d$ : RADIX-SORT works correctly, because of most significant bit dominates regardless of the lower $d-1$ digits.
(2) $a_d = b_d$ : RADIX-SORT leaves $a$ and $b$ in the same order because it is stable sort. The order is correct since lower $d-1$ digits sorts correctly. That's why we need that the intermediate sort must be stable.

Re: [ vuZs.net ] Cs506 Quiz No.1 April 27,2012 correction 4

yes you are right, i did mistake

Abstract classes can not be created directly, instead you need to create an instance via a derived class, that is why you are getting the exception.

http://stackoverflow.com/questions/2553136/cannot-create-instance-of-abstract-class

On Sat, Apr 28, 2012 at 12:15 PM, Zubair Hussain <zubair@vuzs.net> wrote:

An instance of abstract class cannot be created.

TRUE (right answer)
FALSE

The class which can not be instantiated is known as an Abstract Class
