I got an email about being plagiarized in the contest for the second question i.e. problem B. The solution is very straightforward and that's why the system checking might have made a mistake while comparing the solution. The 2 submissions are mine and the ID which submitted a similar solution as mine, I have been threatened in the mail that my account is gonna be banned. Please look after your system because I got this notice for the second time.
