Now I appreciate the effort you guys are putting into preventing cheating. I cannot find a way to prove my innocence ,furthermore I don't think he copied my solution, since he solved both problems before me. I actually lost points in this contest, so it worked out in my favor this time. With that being said id like my minus points back and a guarantee that such mistake won't take place again.

Your solution 113241228 for the problem 1509B significantly coincides with solutions anish_kr_jha/113203828, dicfore/113241228. Such a coincidence is a clear rules violation. Note that unintentional leakage is also a violation. For example, do not use ideone.com with the default settings (public access to your code). If you have conclusive evidence that a coincidence has occurred due to the use of a common source published before the competition, write a comment to post about the round with all the details.
