@admin please take a look at this profile andhis answer during the october long challenge which is the exact same as this answer. He din’t even change the fu*king comments !!!. I don’t if the other person is involved in this. I have already mailed to codechef, I did not get an acknowledgement reply and his account is still active which means that no action has been taken.
NOTE : this is a genuine attempt to make codechef a better place and not to deface or gain attention. The recent case of http://discuss.codechef.com/questions/53541/plagiarism-in-anumla-very-shameful also has motivated me to write this. Hope the admins take note of this. And I will delete all this as soon as some action is taken.
