I've just received a message from the System that says: "Attention!

Your solution 41482612 for the problem 1020B significantly coincides with solutions missed2/41482594, Alilo-Sy/41482612. 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. More information can be found at http://codeforces.com/blog/entry/8790. Such violation of the rules may be the reason for blocking your account or other penalties." And when I searched for the missed2 handle and look in his submissions I get shocked when I saw that his submission to 1020B - Бейджик 41482594 is just as my submission 41482612 literally. I always use ideone and I didn't change anything in its settings because I didn't know that I have to make my code private so I was forbidden from rating and all my labors are in vain :(
