The Ranklist of online preliminary round of ICPC conducted by CodeChef was modified by removing a question "SUMOR". Not only our team but many teams from all over India spent their time solving this question and many of them even got AC. But then suddenly they removed the question making the time we spent on that problem useless. That time would have been spent on some other problem which we could have solved. The removal of that problem clearly affected year long practice and time spent. This matter really needs some concern from CodeChef and higher authorities of ICPC India Regionals.
