For example:Given binary tree [1,null,2,3],return [1,3,2]. The topic requires completion of the two-fork tree sequence traversal, recursive solution is too simple we do n

.==========================================================================================In fact, this problem in the general environment has been resolved OK.My side is caused by other reasons, the analysis continues: is not my local environment problem? So contacted the middleware classmate, found us tomcat under a basic service SAR packet, this SAR packet due to the version is too low, and Mina service

The job of a network administrator is often to diagnose and troubleshoot a variety of server failures. Although no one likes trouble, but trouble always find their own door. Only with superb diagnostic skills can you respond quickly in an emergency and ensure that your network runs smoothly. The following Hengyang high-anti-machine room technical staff summed up some common problems in the server solution, and rented a server friend Exchange.When you're challenged by a network failure, start by

reversal of the surface of the question, there are many ways of implementation, I see the better way to share it, this way also feel with me above that thinking problem a bit similar feeling, personal feeling encounter string reversal of the problem, many will think of loops or something. The method was unexpected. The code is as follows:public static string reverse (string originstr) { if (orig

Write in frontThis problem is a very easy to think of the greedy topic, but the correctness of the proof is very complex. However, at present, all the questions on the Internet do not give any correctness proof of the greedy algorithm, all only stay in the description of a greedy algorithm. Based on the love of Algorithms and Computer Science (escape), I spent 2 weeks in-depth study of the

doubted that it was a Mac system, thinking it was not windows and how it crashed. Well, it turned out that I was paranoid and wronged them both.This is a bug that angular compiles a recursive instruction. Simple verification: The recursive HTML code to comment out, and then refresh the browser page, as expected normal display! Actually can make this kind of mistake, first despise a bit angularjs. After all, I was using angular's first brother, encountered this

solution, where a[i] means the number of columns in row I of the Empress I (note that the value of I is calculated from 0), the following is a simple rule-to-problem extraction process for the eight Queens problem. (1) Because all queens cannot be placed in the same column, the array cannot have the same two values. (2) All Queens cannot be on the diagonal, so how to detect whether the two queens are on th
