![]() Method #1: You could check each book by shelves, one by one, first to last, until you find the book in question.How do you find a specific book from a library? To illustrate this, let’s say you want to find a specific book in a library. Generally speaking, a data structure is a way to organize data, while an algorithm is a method or pattern for solving problems. What is data structure and algorithm essentially? In this article, I’ll argue otherwise: after a few months of directed study and practice, you’ll be able to approach the subject with confidence. You don’t need a high IQ or abstract mathematical knowledge.Īs long as you understand high school mathematics, you have the tools needed to understand data structures and algorithms. Don’t be intimidated by mathematicsĭata structures and algorithms do involve some mathematical reasoning and proofs, particularly when analyzing the time- and space-complexity of an algorithm.īeing able to perform a big-O complexity analysis is certainly important, but you don’t need to worry about it too much to start with. ![]() Be patient, and always keep moving forward. I’m going to tell you about my roadmap and tips. The reason you feel that way is that you haven’t found the right method to let you study the subject deliberately. I had the same reaction when I started learning about the subject. The terms data structures and algorithms both sound abstract and obscure.ĭon’t worry, though. I came, I saw, I conqueredĪs a beginner, you may feel discouraged and frustrated by these concepts. I strongly believe that a thorough knowledge and skill of these two topics are the key to becoming a better programmer.Īn engineer with a deep understanding of algorithms and data structures will be able to make informed design choices, and write programs that are more performant and easier to change. Data structures and algorithms are essential for any programmer.
