I was solving 1684D - Traps of recent contest and have faced with strange thing.
Pls look at two pairs of submissions. (There are very simple code)
In both pairs codes' difference is the same: 'wrong' submission uses lambda function with operator >=
instead of >
in 'good' submission.
Can it be explained?

Thank you.
if comparator returns true for (a, b) it should return false for (b, a). otherwise it's undefined behavior
Thank you.
