Solution: https://github.com/deepak-sharma-iOS/Leetcode-Daily-Challenge/blob/main/Leetcode-2536.java

Summary:
This solution uses a **2D difference matrix** to mark rectangle updates in O(1) time per query by updating only the four corners.
After all queries, it applies **row-wise and column-wise prefix sums** to spread these updates across the grid.
Finally, it extracts the first `n × n` portion, producing the fully updated matrix in **O(n² + queries)** time.
