Getting WA for this solution.

What’s wrong with this solution?
There’s a special case in the loop when l+1==r
I think you are also missing the special case with l+1==r

Hey ,where is the editorial (official) of this problem?
I’m still working on it. I hope people can be understanding with late editorials. Detailed writeups take a lot of time, and by the way, a lot of the problems for this contest (including SWAPPALI) were not fully prepared until several hours before the contest. There was even one problem that was finished 5 minutes before the contest started.
Ok take your time.
