I just recieved a message saying that my solution in the last div.3 contest coincided with someone else's. I'm mistakenly accused of cheating in #719 (Div. 3)

Attention!

Your solution 115267864 for the problem 1520C - Not Adjacent Matrix significantly coincides with solutions Chaturved/115261480, EasonCookie197/115267864, natasha_25/115272375. 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. In case of repeated violations, your account may be blocked.

I swear that I didn't cheat in the contest, and all the codes in this contest are 100% written by me. I didn't use an online IDE. I don't know the other two users. The coincidence is caused by a trivial approach to the problem : just print all the odd numbers and then all the even numbers in order. I believe many other contestants used the exact same method too,with very similar codes. I hope I can get my ratings back. Can someone help me please...

I'm in no way eligible to make any judgements on the codeforces platform. But the solutions submitted by the other two people (Chaturved and natasha_25) are nearly identical. The weird absence of indentation after the two 'if' checks is not typical for natasha_25's coding style (I checked his/her other submitted solutions). They also apparently know each other, because they even belong to the same team. This all makes me think that it looks like a real cheating.

Your solution is very unfortunate to be similar to theirs. If you really don't know these other two persons, then you had a bad day.

Your code looks somewhat different than the other two, while the other two are heavily identical. I don't think you've copied, could be a bad day. Maybe change your template, make a different function for solving different test cases, or something like that.
