My solution for the problem 1395C - Boboniu и битовые операции of the contest Codeforces Round 664 (Div. 2) was uphacked by Lightbender after the contest. So I was looking for the same mistake in other participants' code and found another user with code giving the wrong output on the same test case. Thanks yellow_13 for finding the test case. I feel that many incorrect codes might have been accepted because of weak test cases.
My Submission:- 89709001
Other Submission:- 89699186
The solution fails for the test case
3 2
3 10 128
130 137
The output should be 130 but the code outputs 131. This is the second time in last 3 contests that incorrect codes have been accepted due to weak test cases. I ask the Codeforces community and sshwyR to look into it.

Sorry for that:(
But this round gave a lot of wrong ratings to users who got AC in this problem even after submitting a wrong solution ..
mine was not accepted, bro. :cry:
When I was generating datas, I couldn't imagine the strange solutions for this problem. So I didn't know how to generating strong datas :(
All right, friend. I didn't lose a rating because of that, I only found myself a little terrified when the wa 31 started to appear for everyone with the same solution.But, if I passed the question, I would become cyan again.
That's why multitest exists.
Need moar testers!
