Given the root of a binary tree, consider all root to leaf paths: paths from the root to any leaf. (A leaf is a node with no children.) A node is insufficient if every such root to leaf path intersecting this node has sum strictly less than limit. Delete all insufficient nodes simult...
Anodeisinsufficientif every such root to leaf path intersecting thisnodehas sum strictly less thanlimit. Delete all insufficient nodes simultaneously, and return the root of the resulting binary tree. Example 1: Input: root =[1,2,3,4,-99,-99,7,8,9,-99,-99,12,13,-99,14], limit =1...

For example, the root-to-leaf path 1 -> 2 -> 3 represents the number 123. Returnthe total sum of all root-to-leaf numbers. Test cases are generated so that the answer will fit in a32-bitinteger. Aleafnode is a node with no children. ...
Given a binary tree, each node has 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. ...
An example is the root-to-leaf path 1->2->3 which represents the number 123. Find the total sum of all root-to-leaf numbers. Note:A leaf is a node with no children. Example: Input: [1,2,3] ...
The root-to-leaf path1->2represents the number12. The root-to-leaf path1->3represents the number13. Return the sum = 12 + 13 =25. 思路:每条root到叶节点的路径代表着一个数。沿着路径,各节点的值在数中由高位到低位,这个有点像在数组中,数组A[]的元素是0~9的整数,求由整个数组元素构成整数...
