Solve A 2D Array Maze Using Recursion And JavaScript

To continue on the topic of popular interview questions for software engineering positions, I figured it might be appropriate to go over solving a maze that was created using a two-dimensional array.

A maze created from a 2D array can be solved using recursion similar to like we did for the previous Fibonacci article I made.

Properly Testing Your Ionic Framework Mobile Application

I am very active on Stack Overflow, the Ionic Framework forums, Twitter, and even my own blog. I like helping people and I like seeing that everyone who seeks my help becomes successful in their work.

A common thing I see with the people that I help is they are unfamiliar with how to properly troubleshoot their code. Previously I had written an article regarding how to view the ADB debug logs when testing, but even that has proven to have loose ends. It did a wonderful job on educating everyone how to access the logs, but not so much in the realm of testing and understanding what is seen.

The following will help you rid your project of common errors and problems.

Validate Bracket And Parenthesis Combos Using Stacks

Job interviews for software engineering and other programming positions can be tough. There are too many things to study, and even then it still might not be enough. Previously I had written about a common Fibonacci number algorithm and finding duplicate values in array.

Those skill refreshers were written in JavaScript. This time we are going to take a turn and validate bracket combinations using the Java programming language.

Prompt User To Rate Ionic Framework Mobile App

So you’ve released a great mobile app and have had a decent amount of downloads, but no one is rating or reviewing it. Downloads can be increased significantly by having a greater number of ratings.

So how do you encourage more downloads in your Ionic Framework Android or iOS mobile application? Thanks to a library created by Alex Disler called ng-special-offer, we can make use of Apache Cordova native dialogs to prompt users to rate or review based on application open count.

Calculate If Duplicates Exist In An Array Using JavaScript

You’ll notice previously I did a post regarding the Fibonacci number, a popular interview question for programming jobs. To keep up with this trend of interview questions, we’re going to look into the different ways of finding duplicates in an array.

Finding array duplicates is a good question because it tests your knowledge of algorithm design and your understanding of various time complexities.

Use The Ionic CLI To Integrate Crosswalk Into Your Project

Not too long ago I wrote a very popular tutorial for integrating Crosswalk into your Ionic Framework mobile application. Since then, the guys at Ionic released version 1.3.2 of their CLI and it makes the process even easier than I had previously demonstrated.

The CLI integration is still beta and there is a lot of confusion around it, but this article should clear things up in regards to its usage.

The Fibonacci Sequence Printed With JavaScript

If you’re familiar with the material I write on my blog, you’ll probably be confused at why I’m making such a post. Anyone who has been a part of a Computer Science program at a university will probably have dabbled with Fibonacci in their first semester of school. However, many Computer Science graduates don’t realize that this is a common job interview question regardless of the company or job level that you’re applying for. Whether you’re applying for a new graduate position or a senior level position, there is a good chance you’re going to be screened with a question on this topic.

With that said, I think this can be a refresher to anyone going through the interview process for a programming or software engineering position.
