Recursion Explained with Examples

In this Data Structures tutorial, we will understand What Is Recursion in programming? with the help of an example. This video will acquaint you with a clear understanding of how recursion works in the memory area. Further, this Recursion Explained video will cover the coding implementation of one basic recursive problem.
So, let's get started!

What Is a Data Structure?
The short answer is: a data structure is a specific means of organizing data in a system to access and use. The long answer is a data structure is a blend of data organization, management, retrieval, and storage, brought together into one format that allows efficient access and modification. It’s collecting data values, the relationships they share, and the applicable functions or operations.

Why Is Data Structure Important?
The digital world processes an increasing amount of data every year. According to Forbes, there are 2.5 quintillion bytes of data generated daily. The world created over 90 percent of the existing data in 2018 in the previous two years! The Internet of Things (IoT) is responsible for a significant part of this data explosion. Data structures are necessary to manage the massive amounts of generated data and a critical factor in boosting algorithm efficiency. Finally, since nearly all software applications use data structures and algorithms, your education path needs to include learning data structure and algorithms if you want a career as a data scientist or programmer. Interviewers want qualified candidates who understand how to use data structures and algorithms, so the more you know about the concepts, the more comfortably and confidently you will answer data structure interview questions.

While You Don't Understand Recursion, Read Recursion: by Randy Taylor

Recursion is the one idea I constantly use while I solve coding problems. Most of the time I don’t start by thinking “RECURSION WILL SOLVE THIS!”. However recursion just ends up being the logical way to reach an answer. In my professional opinion recursion is the purest form of coding; write a function that will call itself until you get what you want! To implement recursion we will create a helper algorithm. 1) Identify what the smallest input is. 2) Continually break down a larger input into smaller inputs and pass those smaller inputs back into itself until you get the desired answer. 3) Define a “base case” that will stop the Recursion should the answer not be found.

Let’s look at the idea of Recursion first. We are writing code that will execute itself until we get a desired answer or reach a base case. Essentially we are creating a loop. I will illustrate this with pseudo code:

for (let recursion =()=>{ …answer? answer = true : false} ; answer === false; recursion())

Much like a traditional for loop the above pseudo code will continue while the second condition is true; the recursion will continue until answer === true. At this point the second statement of the for loop is false terminating the loop. Above if answer === false recursion will call itself again. This is the general idea of recursion. This is why creating a base case is essential to prevent an infinite loop. The “answer” we are looking for might not be present causing recursion to run until the sun burns out.

Private Constructor in Java: Use Cases Explained with Example

Introduction

A private constructor in Java is used in restricting object creation. It is a special instance constructor used in static member-only classes. If a constructor is declared as private, then its objects are only accessible from within the declared class. You cannot access its objects from outside the constructor class.

Private Constructor Use-Cases

Private constructors in Java are accessed only from within the class. You cannot access a private constructor from any other class. If the object is yet not initialised, then you can write a public function to call the private instructor. If the object is already initialised, then you can only return the instance of that object. A private constructor in Java has the following use-cases:

  • You can use it with static members-only classes.
  • You can use it with static utility or constant classes.
  • You can use it to serve singleton classes.
  • You can use it to assign a name, for instance, creation by utilising factory methods.
  • You can use it to prevent subclassing.

Singleton Class

The private constructor in Java is used to create a singleton class. A singleton class is a class in Java that limits the number of objects of the declared class to one. A private constructor in Java ensures that only one object is created at a time. It restricts the class instances within the declared class so that no class instance can be created outside the declared class. You can use the singleton class in networking and database connectivity concepts.

3 Examples Of Design Applications With Great UX

When it comes to design, it has long been said that simplicity is key. And although I always understood the basis for this saying, I never fully appreciated what it really meant.

As a beginner it is natural to want to show all your ability by wowing your audience. And as a teacher I see my students making this mistake often. They try to build out features as much as possible and try to showcase every aspect of their ability. As many of you know, this approach does not always result in the most aesthetically pleasing design, let alone the most user friendly experience. This is why I have stressed the importance of simplicity to all my students from the first day I started teaching.

For our latest project, I assigned teams of 4 to each create a prototype for a design application.
