海外TECH	DEV Community	Deploying software is like opening a new bakery 🧁	https://dev.to/svemaraju/deploying-software-is-like-opening-a-new-bakery-2860	Deploying software is like opening a new bakery What the hell is a deployment That s what my wife asked me when she came across this word on her beginner s IT course I was honestly stumped Software development is full of jargon As I have spent years working in this field I have developed a habit of collecting the jargon and using it as shortcuts to communicate ideas But only when she asked me this question that I realised how confusing it can be for a newcomer to understand the dense language of software development Words like deployment production DevOps CI CD pipelines are powerful in communicating broad ideas but are very hard to understand if you ve never seen them in practice For this reason we must take a moment to bring back simplicity to how we explain and communicate This was my attempt to do that I have obviously over simplified some aspects but the goal was to introduce the concept in an approachable way Imagine you re an aspiring baker with a passion for creating mouthwatering treats You ve spent weeks perfecting your recipes for delicious bakery items like cakes cookies and pastries Now it s time to open your bakery and share your creations with the world Here s how the bakery setup process aligns with software deployment Bakery Items Software Just like you ve prepared a variety of bakery items in software development you ve written code to create different software applications or services that serve specific purposes However is not always the case that software is the product sometimes software is what enables you to sell your product Recipe Testing Testing Before your bakery s grand opening you meticulously test each recipe to ensure the taste texture and presentation are just right Similarly during software development developers rigorously test the software to identify and fix any bugs or issues You might seek opinion of your family or friends to know if your pastries taste good likewise a software is shared with a select group of people to understand if it meets their needs Bakery Equipment Infrastructure You invest in essential bakery equipment like ovens mixers and cutlery to help you prepare your delectable treats Similarly in software development you set up a server or cloud infrastructure with the necessary hardware and software to run your applications A server is just a computer in a data center that runs your software and makes it accessible over the internet Bakery Display Packaging In your bakery you beautifully present your treats on shelves and displays making them inviting for customers Likewise in software deployment you package your application along with its required files and dependencies ready to be showcased in the production environment Software applications are usually developed on top other foundational software Hence packaging them all to work together is essential just like how you d arrange a bakery with all its moving parts Grand Bakery Opening Deployment Finally the big day arrives You open the doors of your bakery to the public inviting them to taste and enjoy your delightful creations Similarly when deploying software you make the applications available to users allowing them to access and benefit from their features You would hear terms like Going Live Launching or Going to production It is the digital equivalent of putting an Open sign on your bakery Customer Experience Monitoring As customers visit your bakery you ensure they have a delightful experience by maintaining a clean and inviting atmosphere and offering excellent customer service In the software realm you monitor the application s performance ensuring it runs smoothly and efficiently for users Feedback and Improvements Updates You listen to customer feedback to understand what they love about your treats and where improvements can be made Similarly in software development developers gather user feedback to make updates and enhancements improving the software s functionality and user experience Just as successfully “deploying your bakery brings joy to customers who relish your delicious treats smooth software deployment enables users to access and enjoy your applications helping them in various ways And remember just like a bakery requires ongoing attention and innovation to keep customers coming back for more software applications also need regular monitoring and updates to maintain their reliability and user satisfaction Cover Photo by MichałParzuchowski on Unsplash	2023-08-05 20:42:00
海外TECH	DEV Community	Data Structures - Part 1: Everything You Need to Know About Arrays	https://dev.to/burakboduroglu/data-structures-part-1-everything-you-need-to-know-about-arrays-5d8h	Data Structures Part Everything You Need to Know About ArraysThis blog post part of a series of blog posts on data structures In this blog post we will be covering the following data structures What is an Array How to declare an array With JavaScript and Java Advantages and Disadvantages of ArraysAdvantagesDisadvantagesTime Complexities of Array OperationsBasic Process of Array Operations With JavaScript and Java AddRemoveSorting of Arrays With JavaScript and Java Merge SortQuick SortSearching of Arrays With JavaScript and Java Binary Search Array What is an Array An array is a collection of items stored at contiguous memory locations The idea is to store multiple items of the same type together This makes it easier to calculate the position of each element by simply adding an offset to a base value For simplicity we can think of an array a fleet of stairs where on each step is placed a value let s say one of your friends Here you can identify the location of any of your friends by simply knowing the count of the step they are on Index of an array starts from to size of array For example in the array given below the index of the first element is The index of the last element is let arr int arr How to declare an array In JavaScript we can declare an array in the following ways Method let arr new Array Method let arr Method let arr In Java we can declare an array in the following ways Method int arr new int Method int arr Source GeeksforGeeks Advantages and Disadvantages of Arrays AdvantagesArrays are easy to implement Arrays provide better cache locality that can make a pretty big difference in performance Arrays offer O search if we know the index DisadvantagesThe size of the arrays is fixed So we must know the upper limit on the number of elements in advance Also generally the allocated memory is equal to the upper limit irrespective of the usage Inserting a new element in an array of elements is expensive because the room has to be created for the new elements and to create room existing elements have to shift Deleting an element in an array of elements is expensive because the room has to be created for the new elements and to create room existing elements have to shift Searching in an array is expensive as we have to go through all the elements to find the element we are looking for Time Complexities of Array OperationsOperationTime

Merge sort is a divide and conquer algorithm that was invented by John von Neumann in Merge sort is a sorting technique based on divide and conquer technique With worst case time complexity being Ο n log n it is one of the most respected algorithms How is Merge Sort Algorithm Works Divide the unsorted list into n sublists each containing element a list of element is considered sorted Repeatedly merge sublists to produce new sorted sublists until there is only sublist remaining This will be the sorted list Image Source wikimedia Merge Sort Algorithm Implementationfunction mergeSort arr if arr length lt return arr let mid Math floor arr length let left mergeSort arr slice mid let right mergeSort arr slice mid return merge left right function merge left right let result let i let j while i lt left length amp amp j lt right length if left i lt right j result push left i i else result push right j j while i lt left length result push left i i while j lt right length result push right j j return result let arr console log mergeSort arr public class MergeSort public static void main String args int arr mergeSort arr arr length for int i i lt arr length i System out print arr i public

temp k arr j j k for int l start l lt end l arr l temp l start Quick SortTime Complexity O n log n Space Complexity O log n Quick sort is a highly efficient sorting algorithm and is based on partitioning of array of data into smaller arrays How is Quick Sort Algorithm Works Quick sort works like this Select an element called a pivot from the array Reorder the array so that all elements with values less than the pivot come before the pivot while all elements with values greater than the pivot come after it equal values can go either way After this partitioning the pivot is in its final position This is called the partition operation Recursively apply the above steps to the sub array of elements with smaller values and separately to the sub array of elements with greater values

temp arr i arr i arr end arr end temp return i Searching of ArraysSearching is the process of finding a particular value in a list of values A search typically answers either True or False as to whether the value is present On occasion it may be modified to return where the value is found Binary SearchTime Complexity O log n Space Complexity O Binary search is a fast search algorithm with run time complexity of Ο log n This search algorithm works on the principle of divide and conquer For this algorithm to work properly the data collection should be in the sorted form How Binary Search Algorithm Works Binary search works like this Binary search begins by comparing the middle element of the array with the target value If the target value matches the middle element its position in the array is returned If the target value is less than or greater than the middle element the search continues in the lower or upper half of the array respectively eliminating the other half from consideration Binary Search Algorithm Implementationfunction binarySearch arr target let start let end arr length while start lt end let mid Math floor start end if arr mid target return mid else if
