Question

For a list of n segments, where each segment i has start[i] and end[i], compute for every segment the count of other segments that intersect it (share at least one common point). Return an array counts where counts[i] is the number of intersections for segment i.

Constraints: 1 ≤ n ≤ 10^5, 1 ≤ start[i] ≤ end[i] ≤ 10^9.
