  Algorithm: Traverse binary tree

Preface There are three ways to traverse a binary tree based on the traversing order. Pre-Order: Root - Left - Right In-Order: Left - Root - Right Post-Order: Left - Right - Root Take below binary tree as example The node to be traversed in different order would be Pre-Order: A - B - C - D - E - F In-Order: C - B - D - A - E - F Post-Order: C - D - B - F - E - A Below are the implementations of different orders for traversing the binary tree. Pre-Order Traversing Recursive implementation N...

  Binary tree iterator algorithm

Binary tree pre-order,in-order and post-order traversal are basics in algorithm and data structure.And the recursive binary tree traversal is a classical application of recursion. We define a binary tree node as : // C++ struct Node { int value; Node *left; Node *right; } In order binary tree traversal can be: // C++ void inorder_traverse(Node *node) { if (NULL != node->left) { inorder_traverse(node->left); } do_something(node); if (NULL != node->righ...

  JavaScript Is Not A Language

Recently people presented arguments for and against using CoffeeScript. I felt the argument against was pointless and obviously wrong, but I couldn't figure out why, and I thought the counterargument for was kind of toothless and irrelevant. I've figured out the real issue.The real argument for CoffeeScript is that JavaScript is not really a language.Years ago I read something which explained, in my opinion, why Lisp has never achieved the mainstream adoption its passionate advocates belie...

  Google wins the lawsuit against Oracle

According to The Next Web, San Francisco court has made a final decision that Google didn't violate Oracle's Java patent. Although previously some judges and some people in jury said that Google made some mistakes on Java's use. The final decision made by the court saves Google from the charge of Java patent infringement. The next step of this lawsuit was supposed to be the evaluation of the damage and compensation. But now because of court's decision, this step is jumpe...

  Understand Virtual DOM

With the popularity of React, the internals and implementation of Virtual DOM has becoming top discussed topic in tech communities and interviews. This post will give an introduction of Virtual DOM and how to implement a simple Virtual DOM logic. How to understand Virtual DOM In early days, front end developers would update a webpage view based on the data status change(usually after making AJAX call). But it brings performance penalties when there is frequent update as it would cause page reflo...

  Decision Trees in C#

Decision trees are simple predictive models which map input attributes to a target value using simple conditional rules. Trees are commonly used in problems whose solutions must be readily understandable or explainable by humans, such as in computer-aided diagnostics and credit analysis. Download source code Download sample applications Download the full Accord.NET Framework Introduction Decision Trees give a direct and intuitive way for obtaining the classification of a new instance f...

  Scala Macros

This is the home page of project Kepler, an ongoing effort towards bringing compile-time metaprogramming to Scala. Our flavor of macros is reminiscent of Lisp macros, adapted to incorporate type safety and rich syntax. Unlike infamous C/C++ preprocessor macros, Scala macros: 1) are written in full-fledged Scala, 2) work with expression trees, not with raw strings, 3) cannot change syntax of Scala. You can learn more about our vision of metaprogramming from our talks. We propose to enrich Scala ...

  Chrome is dominating the browser world

Microsoft has announced recently that their Edge browser will abandon its own kernel and switch to use Google Chromium. This by no means indicates that Microsoft admitted it lost the war against Google on browser. For Microsoft, making such a decision is certainly not easy, but it is absolutely a wise decision. After all, the market share of both parties are not at the same competing level anymore. According to NetMarketShare's statistics, Chrome's market share in desktop world has reached 67.29...

  The magic of go:linkname

When writing Go program, there is frequent need on using time.Sleep() function to pause the logic for some time. And if jumping to the definition of this function, can see below definition: // Sleep pauses the current goroutine for at least the duration d. // A negative or zero duration causes Sleep to return immediately. func Sleep(d Duration) I's strange that there is no function body defined here. What happened? The actual definition of the function body is residing at runtime/time.go&nb...

  Building the new AJAX mail UI part 2: Better than templates, building highly dynamic web pages

This is part 2 of a series of technical posts documenting some of the interesting work and technologies we’ve used to power the new interface (see also part 1, Instant notifications of new emails via eventsource/server-sent events). Regular users can skip these posts, but we hope technical users find them interesting. As dynamic websites constructed entirely on the client side become de rigueur, there are a number of templating languages battling it out to become the One True Wayâ„...
