Problem Statement

Summer vacation ended at last and the second semester has begun.
You, a Kyoto University student, came to university and heard a rumor that somebody will barricade the entrance of your classroom.
The barricade will be built just before the start of the A-th class and removed by Kyoto University students just before the start of the B-th class.
All the classes conducted when the barricade is blocking the entrance will be cancelled and you will not be able to attend them.
Today you take N classes and class i is conducted in the t_i-th period.
You take at most one class in each period.
Find the number of classes you can attend.
