Question

You are given two positive, whole number values. Count how many numbers that fall between low and high are probably prime.
To determine if a number is prime, we want a probable certainty of no less than 1-(1/2^40). This is a probability that is really, really close to being absolutely certain.

Input Format

You will input two numbers, each is on it's own line.

Constraints

The numbers will range between 2 and 1,267,650,600,228,229,401,496,703,205,377
The difference between the two numbers will not be greater than 1000

Output Format

Output a single value containing the prime count.

Sample Input 0

218

Sample Output 0

7

Explanation 0

2, 3, 5, 7, 11, 13, and 17

Sample Input 1

752

Sample Output 1

21

Explanation 1

Note that there is no period and the first input line is larger than the second

Sample Input 2
