I recently studied zookeeper storm Kafka. By the way, I set up a local cluster and encountered a zookeeper log problem with the output path. I found that zookeeper sets log4j. properties cannot solve the Log Path problem. The solution is as follows:

The idea at the beginning was: In-order traversal + judgment of the traversed array, the time space was not optimal. It timed out. 1 /** 2 * Definition for binary tree 3 * struct TreeNode { 4 * int val; 5 * TreeNode *left; 6 *
