Given therootof a binary tree, consider allroot to leaf paths: paths from the root to any leaf. (A leaf is a node with no children.) Anodeisinsufficientif every such root to leaf path intersecting thisnodehas sum strictly less thanlimit. Delete all insufficient nodes simultaneously, and re...
You are given therootof a binary tree where each node has a value0or1. Each root-to-leaf path represents a binary number starting with the most significant bit. For example, if the path is0 -> 1 -> 1 -> 0 -> 1, then this could represent01101in binary, which is13. For all le...

04-二叉平衡树1 Root of AVL Tree (20 分) An AVL tree is a self-balancing binary search tree. In an AVL tree, the heights of the two child subtrees of any node differ by at most one; if at any time they differ by more than one, rebalancing is done to restore this property. Figu...

1080. 根到叶路径上的不足节点 - 给你二叉树的根节点 root 和一个整数 limit ,请你同时删除树中所有 不足节点 ,并返回最终二叉树的根节点。 假如通过节点 node 的每种可能的 “根-叶” 路径上值的总和全都小于给定的 limit,则该节点被称之为 不足节点 ,需要被删除。
