SEARCH KEYWORD -- RECURSION

  Traditional recursion vs Tail recursion

Recursion is a frequently adopted pattern for solving some sort of algorithm problems which need to divide and conquer a big issue and solve the smaller but the same issue first. For example, calculating fibonacci  accumulating sum and calculating factorials. In these kinds of issues, recursion is more straightforward than their loop counterpart. Furthermore, recursion may need less code and looks more concise. For example, let's calculate sum of a set of numbers starting with 0 and st...

  Do you have this kind of comments in your source code?

Writing runnable code is the essential skill of a programmer, writing understandable comment is also a skill a programmer should acquire. There is some famous saying that bad comment is worth than no comment. Usually your code will be maintained by other people, if you provide them some difficult to understand or misguided comments, this will be nightmare to them. While at some other time, programmers may put some funny comments in their codes which may make others laugh. Today we...

  Resolve SystemStackError issue when resolving IP address in Ruby

In Ruby, Resolv is the default DNS resolution implementation. It can be used to resolve IP address of a hostname. To use it, one just needs to require 'resolv' in the code. But sometimes, a user would want to check /etc/hosts first or some other mechanisms to resolve an IP address. In this case, one can require 'resolv-replace' and then replace the default DNS resolvers with customized DNS resolvers. For example, using resolv-replace, one would write require 'resolv-replace' Resolv::DefaultResol...

  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...

  Want to write some code? Get away from your computer!

I’ve recently realised something. The best place to write code isn’t in front of your computer, with your compiler, IDE and tools. The best place to write code is far, far away from any of these tools – somewhere where you can think properly. For a language with which you are fairly familiar, the mechanics of translating the program in your mind to a program that the compiler can compile (or the interpreter can interpret) is fairly easy – it’s coming ...

  Haskell’s effect on my C++: exploit the type system

Like most programmers, I was attracted to Scheme by the promise that it would make me a better programmer. I came to appreciate the functional style, but swapped to Haskell, a more developed language with a rapidly developing standard library. Unfortunately, for me, Haskell can’t yet replace C++ on a day to day basis, so I reluctantly spend my days tapping away at C++. So, were the promises true? has functional programming made me a better programmer? Better is a tough question,...

  10 Tips To Make Your C Program Effective

The beauty of any code lies not only in finding the solution to a given problem but is in its simplicity, effectiveness, compactness and efficiency( memory ). Designing the code is harder than actually implementing it. Hence every programmer should keep a couple of basic things in mind while programming in C. Here we introduce you to such 10 ways of standardizing your C code. 1. Avoid unwarranted function calls Consider the following two functions: view source print? 1 void str_print( c...

  The Anatomy of a Perfect Web Site

Many sites on the web are good. They are well-designed, clear, have great information architecture and are easy to navigate. Often, web designers emphasize the “design” part too much, and neglect the other equally important things. However, there are sites which aren’t that aesthetically pleasing, but still are the best sites in the world. They may look like a big, sad bag of wrestling underwear on the outside, but their underlying user experience is really, really refine...

  What? You tattooed code on your arm?

Since I'm seeing so many hits for this page, and since most of you are developers, I thought it might be worth trying to do a little blatant recruiting If you are an exceptional, passionate front end developer (HTML, CSS, JS) and you want to work in an awesome SCRUM team at a huge multinational company in the South of the Netherlands, please drop me a line (DM my Twitter account).There are also opportunities for developers (front and/or back end) and UNIX gurus at another brilliant com...

  "Programmer" is an Overgeneralization

"Beware of bugs in the above code; I have only proved it correct, not tried it." - Donald Knuth Earlier today, I came across a post during a google-fu session that claimed that no one should use the C++ standard library function make_heap, because almost nobody uses it correctly. I immediately started mentally ranting about how utterly ridiculous this claim is, because anyone whose gone to a basic algorithm class would know how to properly use make_heap. Then I started thinking about all the ...
