-/**
- * 370. Range Addition
- *
- * Assume you have an array of length n initialized with all 0's and are given k update operations.
- * Each operation is represented as a triplet: [startIndex, endIndex, inc]
- * which increments each element of subarray A[startIndex ... endIndex] (startIndex and endIndex inclusive) with inc.
- * Return the modified array after all k operations were executed.
-
- Example:
-
- Given:
-
- length = 5,
- updates = [
- [1,  3,  2],
- [2,  4,  3],
- [0,  2, -2]
- ]
-
- Output:
-
- [-2, 0, 3, 5, 3]
- Explanation:
-
- Initial state:
- [ 0, 0, 0, 0, 0 ]
-
- After applying operation [1, 3, 2]:
- [ 0, 2, 2, 2, 0 ]
-
- After applying operation [2, 4, 3]:
- [ 0, 2, 5, 5, 3 ]
-
- After applying operation [0, 2, -2]:
- [-2, 0, 3, 5, 3 ]
-
- Hint:
- Thinking of using advanced data structures? You are thinking it too complicated.
- For each update operation, do you really need to update all elements between i and j?
- Update only the first and end element is sufficient.
- The optimal time complexity is O(k + n) and uses O(1) extra space.
