海外TECH	DEV Community	Every Dev should understand Big O!	https://dev.to/naubit/every-dev-should-understand-big-o-261l	Every Dev should understand Big O This section is all about understanding the Big O and Time complexity of algorithms in minutes or less It is a beginner level section so it should not be too difficult to understand Big OBig O notation measures an algorithm s execution efficiency and how much memory it consumes It can be thought of as either its time complexity or space complexity Whenever we talk about Big O and its efficiency measure we are interested in how well an algorithm performs when the size of our input increases Big O helps to distinguish good from bad code and also bad from great codeThe most common time complexity you may have heard of or come across is O n O n O log n and O n log n I will talk about each of these in detail in a little bit O    Constant TimeAn algorithm is said to run in constant time if it requires the same amount of time regardless of the input size This algorithm has a time complexity of O O n    Linear TimeAlgorithms with a time complexity O n are programmed to have an execution time directly proportional to the input size This notation is also referred to as Linear time The following algorithm has a time complexity of O n where n is the length of the input array Big O Analysis   Best Average amp Worst casesBefore we continue to the more basic Big Os it s worth knowing the different cases Best Case Analysis   Here we calculate the best or minimum time an algorithm takes to finish Average Case Analysis   To calculate the average case of our algorithm we need to be aware of all possible inputs it will receive We then take the time for each use of this input and divide it by the number of inputs Worst Case Analysis   Here we calculate the maximum time taken by the algorithm to finish Look at this example Here we have a function that searches for a player named Kane from a list of players It returns true if the player is found else returns false The best case here is that Kane is at the beginning the first element and we need to loop the player list only once The worst case is that Kane instead of being the rd element is now present at the very end or worse not in the list for which our program needs to iterate through every element in the list We only care about worst case scenarios when we re talking about time complexity Maybe you are wondering why Let s say your code performs well on an average input but it takes an unacceptable amount of time for specific inputs As a programmer it is crucial to be aware of such scenarios and work out ways to optimize them or amend the algorithm This is why people only discuss or care about the worst case complexity of your program during interviews O n² The time taken by the algorithm increases exponentially as the number of elements being iterated on n increases So for example if you increase the input by x you might need to wait times as long for your desired output To understand this better consider the following examples As you can see the computation time increases at an exponential pace of n² item second items seconds items secondsTypically but not always nested for loops have a time complexity of O n² Interviews often consider the O n² solution as a brute force approach So it usually means finding much better approaches such as O n log n or even O n is possible O log n To understand this we will first look into the mathematics behind logarithms and then at how they relate to complexity analysis Wikipedia has the following definition for logarithm In mathematics the logarithm is the inverse function of exponentiation That means the logarithm of a given number x is the exponent to which another fixed number the base b must be raised to produce that number x The binary logarithm uses base b and is frequently used in computer science Why base of explained here Now this might be a little hard to understand at first glance so let s try to understand these equations with some examples Now that we ve learned how to calculate log n let s keep increasing N and observe the increase in time complexity log log log log log log …log log M log B Straightforward enough one can see that when input N doubles the time complexity log N increases only by And in comparison to O N you can see how much better O log N performs This time complexity is often found in divide and conquer algorithms which divide the problem into sub problems recursively before merging them again For example Binary Search Merge Sort O N log N etc Some final thoughtsOnce you get a firm grasp on the essential time complexities O n O n² and O log n it is easy to understand other types of complexity like O n³ O n log n O n …and how they work I want to return to the time complexity graph I shared at the beginning of this article Before you leave Understanding Big O is key to progress as a developer since it will help you to understand how to optimize your code since you will be able to calculate its complexity But if you liked the post I post more exciting content in my newsletter you can check it for

海外TECH	DEV Community	Whatsapp Portfolio Website	https://dev.to/dhanushnehru/whatsapp-portfolio-website-3fdo	Whatsapp Portfolio Website IntroductionA portfolio website provides your information to consumers potential clients and job hires It is the place to showcase your work and let the world know who you are and what you are up to When a potential client HR or anyone visits your portfolio site they should get a feel of your strengths and what you are capable of A good portfolio website will surely replace the old fashioned resumes of job seekers Building a portfolio and keeping it updated helps in this case It also helps us to reconnect with what we have done in the past from a single place We all have a variety of portfolio sites to showcase what we do My love for tech has made me think outside the box to build something unique so I built this whatsapp portfolio site So without much explanation let me showcase my Whatsapp portfolio site whatsapp portfolio dhanushnehru netlify app IdeaI just started this with the idea of replicating the WhatsApp UI where portfolio details of a person can be gotten by chat It is more of how you chat in WhatsApp About the siteMy objective in creating this site is to differ from the normal portfolio sites created and also to showcase something as a unique one Being a full stack developer who has worked mostly on the backend I want to create a portfolio site by myself without any external tutorials By building this whatsapp portfolio site I want to learn something and use it as well The portfolio I built uses the following technologies HTMLCSSJavascript FeaturesAboutSkillsResumeEducationAddressContactProjects Further ImprovementsStill some things to improve like testing browser compatibility updating project links customisation etc I m even thinking about having people fill out a form and converting it into a Whatsapp portfolio for them I would definitely build another static portfolio site to showcase my works directly Do drop your portfolio site below for more inspiration Thanks a lot for reading ️Feel free to subscribe to my newsletter for more updates on this Follow me via Twitter Instagram or Github	2022-09-17 15:25:53
