Okay so this was my solution: https://mirror.codeforces.com/contest/1328/submission/74415216

And this is the other guy, whom I do not know at all. agrawalamritanshu82 https://mirror.codeforces.com/contest/1328/submission/74481132

Our solutions do match almost exactly the same, however neither do I use Ideone or any platform where my code can be leaked and neither have I given my solution to that person. It seems like a coincidence since the solution was simple that it matched almost exactly. Now I do kind of feel bad for that guy since his solutions got skipped due to this, what can I do in this case?

In the recent contest and many other contests, the easy version of the problem is brute-force able its usually not much beneficial to solve the hard part first when you can brute force easy version to get more points and also like in https://mirror.codeforces.com/contest/1185

G1 was very easily doable by a brute force solution which I sadly didn't notice and it carried 2750 points.

I suggest that it should be the other way round, easy version should carry lesser points compared to the hard version, 750/2750 would have been a better option.
