Can everyone give me your testdata(s) of ural1216? I have checked a
lot, but I think if we put our testdatas(or ideas) together, the
problem will be solved easily. I want to be the programmer, and you
give me the datas, I test..again and again. Can you help me? If I get
ac, of course I will send my program to you all!!! My ideas you can
