Previously summaryIn the previous article, "Mocha.js 101" Mocha Getting Started, we mentioned how to use mocha.js for front-end automated testing, and made a few simple examples to experience the convenience that Mocha.js brings to us.In this article, we will learn about synchronous/asynchronous testing of mocha.js and how to test Promise.Synchronous Code TestingIn the previous article, we've actually learned how to test the synchronization code.

Given a binary tree, check whether it is a mirror of the itself (ie, symmetric around its center).For example, this binary tree is symmetric: 1 / 2 2/\/3 4 4 3But the following are not: 1 / 2 2 \ 3 3Problem Solving Ideas:Overload a issymmetric to determine whether two trees are symmetrical, Java implementations are as follows: public Boolean issymmetric (TreeNode root) { if (root==null) return true; Return Issymmetric (root.left,root.right); } public

Use tag to differentiate the output sequence. Remember that each time you need tag to reverse, the next is the opposite direction. if (tag) { ret.push_back (level); } else { reverse (level.begin (), Level.end ());

It is well known that Linux does not have a recycle Bin, some people are afraid to delete the wrong things (experienced Linux administrators rarely fan this error), individuals do not recommend the Recycle Bin, but should be to develop personal security awareness. A little digress. then back 101 scripts #15 archiving Files as They ' re removed is a script to build a Linux Recycle Bin #!/bin/sh # NEWRM, a replacement for the existing RM command

101 optimization tips for MySQL databases under the CentOS ServerMySQL server hardware and operating system adjustment: 1. Have enough physical memory to load the entire InnoDB file into the memory. The speed of accessing files in the memory is much faster than that on the hard disk.2. Avoid using Swap to Swap a partition at any cost-the Swap is read from the hard disk, and its speed is very slow.3. Battery-powered RAM (Note: RAM is random memory ).4.

Recommendation 101: Use extension methods to "add" methods to existing typesConsider how to have a new behavior for a sealed type. We used to create a wrapper class and then add a method to it, which doesn't look elegant at all. We might consider modifying the design, modifying the sealed type directly, and then publishing a new version for it, but it relies on you having all the source code. More often, we will take the approach of programming to API
