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.

Solution in C (GCC 5.4.1) (judge verdict: Wrong Answer)

#include <stdio.h>

int main()
{
    long int n,a,b,c,count,i;
    scanf("%ld %ld %ld",&n,&a,&b);
    count=0;
    for(i=0;i<n;i++)
    {
        scanf("%ld",&c);
        if(c<=a ||  c>=b)
        {
            count++;
        }
    }
    printf("%ld",count);

    return 0;
}
