In the last round, I have received unexpected warnings from CodeForces plagiarism checker for the Div-2 contest that was hosted on June 4 2023.The warning says that my submission for the question 1840E was directly coninciding.

In the question we have to check the postion of the the arrays A,B according to the query(positions) given and swapping the values if the query was 1.It was straightforward and most the submissions had to do it as the output was also unique. i got the plag detection by using this algorithm and decremnting the count.

my submission -https://codeforces.com/contest/1840/submission/208801857 question — https://codeforces.com/contest/1840/problem/E

some other submissions -
https://codeforces.com/contest/1840/submission/208772050 https://codeforces.com/contest/1840/submission/208795243

As you can see it was similiar as the algorithm was straightforward but our code was not alike. so i would request @MikeMirzayanov and @diskoteka @isosto @pavlekn @playerr17 (creators of the contest) to look into this. thank you

In the last round, I have received two unexpected warnings from CodeForces plagiarism checker for the Div-2 contest that was hosted on June 3 2023.Both the warning says that my submission for the question 1839C was directly coninciding.

the question was quite straight forward as to the binary array from the end and check if the bitwise OR of that particular array and another alternate 0-1 binary array that was created by just a flag and changing it after every iteration. it was just a simple traversal but the plag checker gave me a plag detection for it .

alternate submissions that were detected as same

https://codeforces.com/contest/1839/submission/208338627

https://codeforces.com/contest/1839/submission/208337577

As you can see the last submission was nowhere near as my solution so i would request @MikeMirzayanov and @valerikk ( creater of the contest ) to please correct this. I never missed a single round regardless of how busy i was. I love my cf profile -_-
