In** problem E** of yesterday's round, I misread the question and thought of a completely different problem the whole time. But this problem might also be interesting for some of you guys. So, here goes the modification:- Instead of swapping any two elements, you can swap only two adjacent elements and the constraint on m<=**n**.

I can share my idea and code also for this problem which I think works. Meanwhile, if any of you guys know any links where we can submit this problem, please share it.

Thanks for reading.
