You are given an integer `length` and an array `updates` where `updates[i] = [startIdxi, endIdxi, inci]`.

You have an array `arr` of length `length` with all zeros, and you have some operation to apply on `arr`. In the `ith` operation, you should increment all the elements `arr[startIdxi], arr[startIdxi + 1], ..., arr[endIdxi]` by `inci`.

Return `arr` after applying all the `update`.

Example 1:

`````` 0 0 0 0 0
0 2 2 2 0
0 2 5 5 3
-2 0 3 5 3
Input: length = 5, updates = [[1,3,2],[2,4,3],[0,2,-2]]
Output: [-2,0,3,5,3]
``````

Example 2:

``````Input: length = 10, updates = [[2,4,6],[5,6,8],[1,9,-4]]
Output: [0,-4,2,2,2,4,4,-4,-4,-4]
``````

Constraints:

• `1 <= length <= 105`
• `0 <= updates.length <= 104`
• `0 <= startIdxi <= endIdxi < length`
• `-1000 <= inci <= 1000`
