There are n flights, and they are labeled from 1 to
n.
We have a list of flight bookings. The i-th booking bookings[i]
= [i, j, k] means that we booked k seats from flights labeled
i to j inclusive.
Return an array answer of length n, representing the number of
seats booked on each flight in order of their label.
Example 1:
Input: bookings = [[1,2,10],[2,3,20],[2,5,25]], n = 5 Output: [10,55,45,25,25]
Constraints:
1 <= bookings.length <= 200001 <= bookings[i][0] <= bookings[i][1] <= n <= 200001 <= bookings[i][2] <= 10000
