海外TECH	DEV Community	Right way to use Blockchain	https://dev.to/darshancodes/right-way-to-use-blockchain-1cfe	Right way to use BlockchainHey there everyone today we re going to learn about how you can use blockchain in right way like what are some of the major ways tips to use it and what actions does it performs So let s get started with an introduction about it What is Blockchain Blockchain technology is a structure that stores transactional records also known as the block of the public in several databases known as the “chain in a network connected through peer to peer nodes Typically this storage is referred to as a digital ledger Every transaction in this ledger is authorized by the digital signature of the owner which authenticates the transaction and safeguards it from tampering Hence the information the digital ledger contains is highly secure In simpler words the digital ledger is like a Google spreadsheet shared among numerous computers in a network in which the transactional records are stored based on actual purchases The fascinating angle is that anybody can see the data but they can t corrupt it Why is Blockchain so popular Record keeping of data and transactions are a crucial part of the business Often this information is handled in house or passed through a third party like brokers bankers or lawyers increasing time cost or both on the business Fortunately Blockchain avoids this long process and facilitates the faster movement of the transaction thereby saving both time and money Most people assume Blockchain and Bitcoin can be used interchangeably but in reality that s not the case Blockchain is the technology capable of supporting various applications related to multiple industries like finance supply chain manufacturing etc but Bitcoin is a currency that relies on Blockchain technology to be secure Advantages of using Blockchain Highly Secure It uses a digital signature feature to conduct fraud free transactions making it impossible to corrupt or change the data of an individual by the other users without a specific digital signature Decentralised System Conventionally you need the approval of regulatory authorities like a government or bank for transactions however with Blockchain transactions are done with the mutual consensus of users resulting in smoother safer and faster transactions Automation Capability It is programmable and can generate systematic actions events and payments automatically when the criteria of the trigger are met Some Right way to use Blockchain Sharing records securely Blockchain could be a solution for sharing the records transactions securely if not then that s not the right way to use blockchain Level up your supply chain management One of the greatest challenges facing manufacturers today is the increasingly complex and opaque global supply chain “With blockchain however you can easily access supplier records information from government agencies and insurers and prior verifications completed by trusted parties all in one place Prevend Fraud and Streamline accounting Blockchain ーwhich initially helped prevent fraud in banking ーcan also be used for media buying With blockchain s open and distributed ledger advertisers can track their investments throughout the process But advertisers won t realize this perk unless all parties in a transaction agree to use the technology Blockchain can also streamline accounting practices in more areas than advertising spend The technology can lighten the load for financial auditors meaning they have more time to focus on anomalies “Blockchain s transparency gives visibility to all transactions for approved users and this may decrease auditors work with sampling and validating transactions ConclusionThis technology has the potential to disrupt nearly every industry and solve your business s greatest challenges By strategically implementing some new solutions you can make your business more secure more transparent and more prepared for whatever s next Thanks	2022-02-27 05:22:38
海外TECH	DEV Community	Day 15 of Studying LeetCode Solution until I Can Solve One on My Own: Problem#453. Minimum Moves to Equal Array Elements(M/JS)	https://dev.to/corndog_com567/day-15-of-studying-leetcode-solution-until-i-can-solve-one-on-my-own-problem453-minimum-moves-to-equal-array-elementsmjs-5ch4	Day of Studying LeetCode Solution until I Can Solve One on My Own Problem Minimum Moves to Equal Array Elements M JS Intro I am a former accountant turned software engineer graduated from coding bootcamp in January Algorithms and Data Structure is an unavoidable part of interviews for most of the tech companies now And one of my friends told me that you need to solve a medium leetcode problem under seconds in order to get into the top tech companies So I thought I d start learning how to do it while job searching Since I have no clue on how to solve any of the problems even the easy ones I thought there is no point for me to waste hours and can t get it figured out Here is my approach Pick a leetcode problem randomly or Online Assessment from targeted companies Study solutions from Youtube or LeetCode discussion section One brute force solution another one more optimal Write a blog post with detailed explanation and do a verbal walk through to help understand the solutions better Code out the solution in LeetCode without looking at the solutionsCombat the forgetting curve Re do the question for the next three days And come back regularly to revisit the problem Minimum Moves to Equal Array Elements It s a Math question Difficulty Medium Language JavaScript Given an integer array nums of size n return the minimum number of moves required to make all array elements equal In one move you can increment n elements of the array by Example Input nums Output Explanation Only three moves are needed remember each moveincrements two elements gt gt gt Example Input nums Output Constraints n nums length lt nums length lt lt nums i lt The answer is guaranteed to fit in a bit integer Solution My first thought was to Get the difference between sum of all array element and largest number n That will give us the number of moves are needed to get all elements to equal to the largest number Because In one move you can increment n elements of the array by the number of moves needed need to be divisible by n If not increase the largest number by until that condition is met For example given array the number of moves needed to get all element to equal to the largest number is But is not divisible by n in this case We increase largest number from to Now the moves needed for all elements to equal to largest number is divided by is Hence moves is the answer for array User spacepumpkin on LeetCode provided a much better idea if we think of it the other way around incrementing n elements other than nums i is effectively the same as decrementing nums i to make all elements equalthus the number of moves to increment n elements is the same as the number of moves to decrement each element to get to the minimumI like to think of each element as a tower of blocks how many blocks do we have to remove so that all towers are at the minimum tower height ex for we have x x x x remove blocks x gt so based on this way of thinking the formula is number of blocks removed sum of all blocks number of towers minimum tower height in our example total blocks number of towers amp minimum tower height Code function minMoves nums let sum nums let min nums Initialize both sum and min variable as first number note in the array for let i i lt nums length i Loop note through nums array and find the total of blocks and min tower height if nums i lt min min nums i if an element if found to be smaller than current min then replace current value of min to that smaller element found To find the min tower height sum nums i add value to every element to sum to get sum of all element total of blocks return sum nums length min blocks removed total blocks towers min height lt refer to explation above regarding removing blocks Solution Submission detail as of Data below could vary since there are new tests submissions daily Runtime msMemory Usage mbReferences LeetCode Problem LinkLeetCode Discussion spacepumpkinNote Loop and IterationNote Access an array item by its indexNote Addition assignment Blog Cover Image Credit	2022-02-27 05:14:41
