Can you solve this real interview question? Insufficient Nodes in Root to Leaf Paths - 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 no
For the non-leaf nodes, val can be arbitrary, so it is represented as *. Note: N is less than 1000 and guaranteened to be a power of 2. If you want to know more about the quad tree, you can refer to its wiki. 【解答】构造 Quad Tree。 没有太多可以说的。递归...
The graph contains n nodes which are labeled from 0 to n - 1. You will be given the number n and a list of undirected edges (each edge is a pair of labels). You can assume that no duplicate edges will appear in edges. Since all edges are undirected, [0,...
