For this Question: You are given N points on a horizontal axis. Find the number of ways you can choose 3 points such that maximum distance between those points is not greater than d.The first line contains two integers: N and d. The next line contains N space-separated integers x1, x2, ..., xN, — the x-coordinates of the points that Petya has got.

<b>Constraints:</b>
1 &le; N &le; 1e5
1 &le; d &le; 1e9
1 &le; |x[i]| &le; 1e9

It is guaranteed that the coordinates of the points in the input strictly increase.Print the number of ways to choose 3 points.Sample Input:
4 3
1 2 3 4

Sample Output:
4

Explanation:
1 2 3
1 2 4
2 3 4
1 3 4
are the required triplets

Sample Input:
4 2
-3 -2 -1 0

Sample Output:
2, I have written this Solution Code: import math

N,d = map(int,input().split())
arr = [int(i) for i in input().split()]
initial = 0
pre = 0
sumi = 0

while(initial<(N-1)):
    low = initial
    high = N-1
    while(low<=high):
        mid = (low+high)>>1
        if arr[mid]-arr[initial]<=d:
            ans = mid
            low = mid+1
        else:
            high = mid-1
    sumi += math.comb((ans-initial)+1,3)-math.comb((pre-initial)+1,3)
    pre = ans
    initial += 1

print(sumi), In this Programming Language: Python, Now tell me if this Code is compilable or not?
