海外TECH	DEV Community	DSA: Search algorithms with JavaScript	https://dev.to/ale3oula/dsa-search-algorithms-with-javascript-2km9	DSA Search algorithms with JavaScript IntroductionTwo of the most fundamental set of algorithms in computer science are Sorting and Searching Search algorithms are step by step instructions to locate some specific data in a collection Types of Search AlgorithmsTwo important search algorithms are Linear SearchBinary SearchIn the next paragraphs we will introduce these two algorithms with examples a code implementation in JavaScript find the time complexity and finally try and solve exercises ExampleSuppose you are searching for the word summer in the dictionary You could start from the first page of the dictionary and keep flipping pages until you reach the S es and find your word there But flipping every page of the dictionary doesn t make sense right Intuitively you know that the words starting with S will probably be after the middle of the dictionary This is a search problem and these two variations of how you can search are the linear and binary search algorithms Linear searchIn a linear search algorithm we don t care if the array is sorted or not The linear algorithm takes as arguments a sorted array and an item The algorithm will traverse the whole collection For each element we ask the question Is this my target value If the item is in the array the function returns its position If the collection traversal finishes and we have not find the target element we return null const linearSearch arr target gt for let i i lt arr length i if arr i target return i return null linearSearch returns the index Binary SearchThe binary search algorithm works on a sorted collection of elements as a dictionary which is sorted alphabetically If the binary search finds the item in the collection it returns true or the position where we find it Otherwise we return a falsy value as null or false The binary search algorithm takes as arguments a sorted array and an item If the item is in the array the function will return its position Each time we check the middle element this is our guess If the guess it is too low we update the low index If the guess is too high we update the high const binarySearch arr item gt let low let high arr length while low lt high const mid Math floor low high if arr mid item return mid else if arr mid lt item low mid else high mid return null binarySearch returns the index The low and high variables keep track of the part of the array we are searching The loop will run until we have one element in the collection For each item we check the middle element and see if it is our targeted item If our guess is too high we discard the second half of the array Otherwise we discard the first half of the array Time complexityTo explain the time complexity let s see an example Imagine we have an array of numbers between and The target is to guess which number i am thinking e g a random number With a linear search algorithm you will start guessing Is it Is it At some point you will find the number If the random number was it would take guesses to get there If the colleciton was consisting billion numbers it would take up to billion guesses So the maximum number of guesses is the same as the size of the collection That means that the linear search algorithm is growing in linear time We call this linear complexity and it is written it as O n For the binary search you will start guessing with the middle element first Is it If this is too low you know that all the numbers in to are also too low In each guess you eliminate half of the array If we have numbers we eliminate to to to to to and So you can find every number between this range with maximum guesses If the list was consisting billion numbers it takes at most guesses We call this logarithmic complexity and we write it as O logn Exercise Search Insert PositionGiven a sorted array of distinct integers and a target value return the index if the target is found If not return the index where it would be if it were inserted in order You must write an algorithm with O log n runtime complexity This problem asks us to write an algorithm of O logn Additionally it mentions that our array is sorted This should make us think the binary search Pseudocode We do the binary search algorith if the element is found we return the positionIf the element is not found the low and high variables will point to the closer valueconst searchInsert nums item gt let start let end nums length while start lt end let mid Math floor start end if nums mid item return mid nums mid gt item end mid start mid if start end return item lt nums start start start searchInsert returns searchInsert returns as if the existed would be between and Exercise Given a m x n matrix grid which is sorted in non increasing order both row wise and column wise return the number of negative numbers in grid For this problem the array is sorted so we find the first negative index So all remaining items are negative const countNegatives function grid let count for let i i lt grid length i const index binarySearch grid i count grid i length index return count const binarySearch arr gt let low let high arr length while low lt high const mid Math floor low high if arr mid lt high mid else low mid return low	2022-06-12 19:28:51
