Relationship between Data Structures and Algorithm
Both Data structures and algorithms are interrelated and complement eachother. An algorithm applies to a particular data structure, while using theright data structure helps to drastically improve the performance of analgorithm. Hence, we can’t detach data structures and algorithms.Following are the main categories of algorithms in relation to datastructures: * Search– This algorithm helps in finding an item in a data structure. * Insert– To insert an item in a data structure, this algorithm is applicable. * Sort– This algorithm is helps to sort items in a specific order. * Update– The update algorithm is useful for updating an existing item in a data structure. * Delete– In order to delete an existing item from a data structure, you can use the delete algorithm.
Reason to Learn Data Structures and Algorithms
Data structures and algorithms are the most pivotal topics for programmers andComputer Science graduates, to get a job & perform well in it. Here are someconsiderable reasons to learn data structures and algorithms: * A comprehensive knowledge of data structures in combination with algorithms is the core foundation of writing good codes. It reduces coding costs & enhances data accuracy, which is the ultimate goal of organizations. * To earn salaries as high as the developers of Amazon and Google, you need to improve your problem-solving abilities by mastering data structures and algorithms. * If you want to generate bug-free results in coding, then it is utmost important to excel these concepts. * Learning data structures and algorithms is also beneficial for a better understanding of new frameworks such as Angular, React, Vue, Spring MVC, etc. * When you get an exposure to a different range of problem-solving techniques, it helps you take up the next challenging problem easily. * Programmers who are competent in data structures and algorithms can easily perform the tasks related to data processing, automated reasoning, or calculations. * Data structure and algorithm is significant for developers as it shows their problem-solving abilities amongst the prospective employers. Thus, amplifies the chances of getting the job.The choice of data structure & algorithm can make a huge difference between aprogram running in few seconds to many days. You can only make a great choiceif you have that level of premier knowledge about data structures andalgorithms.

Why learn computer science?
There are 2 types of software engineer: those who understand computer sciencewell enough to do challenging, innovative work, and those who just get bybecause they’re familiar with a few high level tools.Both call themselves software engineers, and both tend to earn similarsalaries in their early careers. But Type 1 engineers grow in to morefulfilling and well-remunerated work over time, whether that’s valuablecommercial work or breakthrough open-source projects, technical leadership orhigh-quality individual contributions.> The global SMS system does around 20bn messages a day. WhatsApp is now doing> 42bn. With 57 engineers. pic.twitter.com/zZrtSIzhlR>> — Benedict Evans (@BenedictEvans) February 2, 2016Type 1 engineers find ways to learn computer science in depth, whether throughconventional means or by relentlessly learning throughout their careers. Type2 engineers typically stay at the surface, learning specific tools andtechnologies rather than their underlying foundations, only picking up newskills when the winds of technical fashion change.Currently, the number of people entering the industry is rapidly increasing,while the number of CS grads is essentially static. This oversupply of Type 2engineers is starting to reduce their employment opportunities and keep themout of the industry’s more fulfilling work. Whether you’re striving to becomea Type 1 engineer or simply looking for more job security, learning computerscience is the only reliable path.> Lol oh but they were…. pic.twitter.com/XVNYlXAHar>> — Jenna Bilotta (@jenna) March 4, 2017
Algorithms and Data Structures
We agree with decades of common wisdom that familiarity with common algorithmsand data structures is one of the most empowering aspects of a computerscience education. This is also a great place to train one’s general problem-solving abilities, which will pay off in every other area of study.There are hundreds of books available, but our favorite is The AlgorithmDesign Manual by Steven Skiena. He clearly loves this stuff and can’t wait tohelp you understand it. This is a refreshing change, in our opinion, from themore commonly recommended Cormen, Leiserson, Rivest & Stein, or Sedgewickbooks. These last two texts tend to be too proof-heavy for those learning thematerial primarily to help them solve problems.For those who prefer video lectures, Skiena generously provides his online. Wealso really like Tim Roughgarden’s course, available from Stanford’s MOOCplatform Lagunita, or on Coursera. Whether you prefer Skiena’s orRoughgarden’s lecture style will be a matter of personal preference.For practice, our preferred approach is for students to solve problems onLeetcode. These tend to be interesting problems with decent accompanyingsolutions and discussions. They also help you test progress against questionsthat are commonly used in technical interviews at the more competitivesoftware companies. We suggest solving around 100 random leetcode problems aspart of your studies.Finally, we strongly recommend How to Solve It as an excellent and uniqueguide to general problem solving; it’s as applicable to computer science as itis to mathematics.> I have only one method that I recommend extensively—it’s called think before> you write.>> — Richard Hamming
Mathematics for Computer Science
In some ways, computer science is an overgrown branch of applied mathematics.While many software engineers try—and to varying degrees succeed—at ignoringthis, we encourage you to embrace it with direct study. Doing so successfullywill give you an enormous competitive advantage over those who don’t.The most relevant area of math for CS is broadly called “discretemathematics”, where “discrete” is the opposite of “continuous” and is looselya collection of interesting applied math topics outside of calculus. Given thevague definition, it’s not meaningful to try to cover the entire breadth of“discrete mathematics”. A more realistic goal is to build a workingunderstanding of logic, combinatorics and probability, set theory, graphtheory, and a little of the number theory informing cryptography. Linearalgebra is an additional worthwhile area of study, given its importance incomputer graphics and machine learning.Our suggested starting point for discrete mathematics is the set of lecturenotes by László Lovász. Professor Lovász did a good job of making the contentapproachable and intuitive, so this serves as a better starting point thanmore formal texts.For a more advanced treatment, we suggest Mathematics for Computer Science,the book-length lecture notes for the MIT course of the same name. Thatcourse’s video lectures are also freely available, and are our recommendedvideo lectures for discrete math.For linear algebra, we suggest starting with the Essence of linear algebravideo series, followed by Gilbert Strang’s book and video lectures.> If people do not believe that mathematics is simple, it is only because they> do not realize how complicated life is.>> — John von Neumann
