Most large companies always strive for speed as it’s a huge competitive advantage in multiple industries.

Granted you can always import multiple classes and manipulate some methods to accomplish your desired task, but this doesn’t make you a good programmer.Ī clunky code simply leads to problems in the future as well as increased run-time. Why learn data structures and algorithmsĪlthough most programming languages continue to increase the libraries programmers can use in their development, your specific situation may require some more efficiency. Learning Java, C#, JavaScript, PHP, Ruby, Python, or any other programming language is great but an understanding of data structures will help make it easier to understand how the programming language works. This is why most companies in recent years place a huge emphasis on data structures. Without an organizational system, this becomes impossible. Now, imagine how many videos are uploaded to YouTube daily, or even how much information companies like Facebook collect and store daily. It’s been used in our dictionaries and offices for years because of its efficiency. This process is easier and cuts down the time necessary to find any information. Then we can arrange files starting with the same letter, by the letter which follows, and continue to do so with subsequent letters. We can shorten the time necessary to find this file by simply grouping our files by the first letter. Let’s say we’re looking for a file by the name “Priority”. In real life, we can use these devices and use the dictionary method to help identify each file. Maybe a cabinet, folder, or binder to store specific files.
Looking through every scattered file would be a herculean task.įor this reason, we all use some form of organizational system in our offices, homes, and our daily lives. Not only that, imagine needing to look for files containing some specific information. There may be room for all the scattered files but the challenge arises when you need a specific file from the stack of scattered files. Imagine having a bunch of files scattered around your office. To put it simply, data structures enable users to store information more efficiently for easy retrieval and an algorithm is essentially a formula that solves a particular problem. What is data structures and algorithmsĪ data structure is a memory location that can be used to store data to subsequently perform efficient operations on them and an algorithm is an outlined systematic approach or procedure to accomplish a specific action.ĭata structure is the fundamental building block of computer science and necessary for the design and development of efficient software.

It’s only later when I started advancing in software development, that I got to understand the importance of having a better understanding of data structures. Why couldn’t we simply use the LinkedList Class, already available in Java, like it was meant to, in order to make our lives easier, I thought.
In my early years as a programmer, I kept wondering why my Java instructor was wasting our time forcing us to implement our LinkedList data structure. That’s what a bad programmer thinks after successfully compiling their application.Ī good programmer, on the other hand, looks for the most efficient way to solve the problem.
He or she simply writes the code, clunky or not, they simply focus on the code running with little thought to the efficiency of the written code. A bad programmer simply looks for a way to make his code run, while praying for as few bugs as possible.
