1080 - Insufficient Nodes in Root to Leaf Paths\. Medium Given the `root` of a binary tree and an integer `limit`, delete all **insufficient nodes** in the tree simultaneously, and return _the root of the resulting binary tree_. A node is **insufficient** if every root to **leaf** path intersecting this node has a sum strictly less than `limit`. A **leaf** is a node with no children. **Example 1:**  **Input:** root = [1,2,3,4,-99,-99,7,8,9,-99,-99,12,13,-99,14], limit = 1 **Output:** [1,2,3,4,null,null,7,8,9,null,14] **Example 2:**  **Input:** root = [5,4,8,11,null,17,4,7,1,null,null,5,3], limit = 22 **Output:** [5,4,8,11,null,17,4,7,null,null,null,5] **Example 3:**  **Input:** root = [1,2,-3,-5,null,4,null], limit = -1 **Output:** [1,null,-3,4] **Constraints:** * The number of nodes in the tree is in the range `[1, 5000]`. * -105 <= Node.val <= 105 * -109 <= limit <= 109
