Given a array of integers A of size N and an integer B.

Elements in array A represents points where we can cut the pipe, Initial length of pipe is 100 units.
For Example:- if A = [25, 35] pipe an be cut from these points only.

Find and Return the probability of any of all resulting pipe being longer than B meters, If the two cut locations are chosen at random from array A

Note:- As probability can be very small, return the integral part of (probability*10^7).

Input Format

``````The first argument given is the integer array A.
The second argument given is the integer B.
``````

Output Format

``````Return the probability of any of all resulting pipe being longer than B meters,If the two cut locations are chosen at random from array A
``````

Constraints

``````2 <= N <= 50
1 <= A[i] <= 100
1 <= B <= 100
``````

For Example

``````Example Input 1:
A = [25, 50, 75]
B = 25
Example Output 1:
10000000
Example Explanation 1:
Any cut will result in a pipe of greater than 25 meter
probability = 1.00000000000
probability * 10000000 = 10000000

Input 2:
A = [25, 50, 75]
B = 50
Output 2:
0
