I was solving 1684D - Ловушки of recent contest and have faced with strange thing.

Pls look at two pairs of submissions. (There are very simple code)

1. 157815234 — OK, 157815120 — Time limit

2. 157814018 — OK, 157813947 — Run-time error

In both pairs codes' difference is the same: 'wrong' submission uses lambda function with operator >= instead of > in 'good' submission.

Can it be explained?
