Hello everyone
Here in Syria we have a lot of power outages (more than 16 hours everyday), you know, it's the WAR.
but luckily I managed to install ubunto and then CMS. I need your help if you can tell me about online judges that give you it's problems input and output files, like USACO, COCI and Atcoder recently.
thank you very much and sorry for my annoying questions in my last three blogs.
