Top 5 Online Courses to Learn to Code With No Programming Experience- Best of Lot

Programming and/or Coding is one of the important skills for today's technical world and awareness of coding is growing every passing day. In my time, about 20 years back, I only learned to code when I entered into engineering college to pursue Computer Science and Engineering degree, but things have changed a lot since then. Nowadays, even kids have started learning to code, even my daughter can code and much better than what I can do even in college. More accessible computing gadgets like iPad, iPhone, Smartphone and Laptops has truly changed the environment and made Coding or Programming more accessible.

5 Websites to Learn SQL Online for FREE

The SQL is one of the most important skills for any programmer be it a Java, C++, Python, JavaScript, or Ruby developer. Almost 95% of the Java applications use a relational database in their back-end and almost all web applications use the database. In recent years, one of the most common way to learn any programming skill is online, at your comfort of the office or home and SQL is no different. Learning SQL online has another advantage of a quick head start because you don't need to install a database and create tables to write some SELECT queries. The installation and setup is definitely a tough part for beginners and I have gone through that pain every time I have to learn a new database.

I have decided to jot down some new resolutions for Java programmers to improve themselves, enhance their knowledge on Java Programming and increase their value for future career growth.

Top 20 String Algorithm Questions from Coding Interviews

In this article, we are going to see top 20 String based coding interview question and their solution to help programmers better prepare for interviews. The string is one of the most important data structure and available in almost every programming language like Java, C, C++, Python, Perl, and Ruby. Though there implement differ the essence remains same like String is NULL terminated character array in C but String is an object in Java, again backed by character array. The string is also available on weekly typed languages like Python and Perl.  This is why you will always find some String based coding question on programming interview.

Top 5 Data Science and Machine Learning Courses to Learn Online - Best of Lot

How to Reverse a linked list in Java Using Recursion and Iteration (Loop) - Example

This is one of the class coding problems from Programming job interviews. It may seem easy to reverse a linked list but when you go around doing the actual task, it's not that easy, especially for first-timers. There are a couple of algorithms exists to reverse a singly linked list in Java like you can use the three-pointers approach or solve this problem using a Stack, or simply using Recursion without the external stack. As I had pointed out on the earlier post about linked list, that reversing a linked list is one of the most popular linked list based data structure interview question. This means, you just can't afford to prepare this one, before going for any programming interview. Despite being so common, It's not easy to solve this problem on the fly.
