Please do share below in the comments. I like the tree diagram it made everything clicked for me. 5) Some of the loops result in single element arrays, but I only want to look at the ones with more than one, as we're trying to split my word into two elements. If yes, this condition should return true because it means that there is some combination of elements that add up to the max number, otherwise return false. your sort is sorting strings, not numbers. Coderbyte | The #1 Coding Assessment Platform Code and interview better on the #1 platform for 1M+ developers that want to take their careers to the next level. Here is my approach to solving this problem using recursion to determine combinations of elements in the array: When trying to solve this problem, I first started with pseudocoding my plan of attack: Consider edge cases: Because we are given the assumption that arr will not contain all of the same elements, we can infer that an array with less than or equal to 2 elements cannot meet the requirements. console.log(firstWord, splitMainWordArray, 'splitMainWordArray'), This is not correct solution as it's will still return the hello , cat if pass this To subscribe to this RSS feed, copy and paste this URL into your RSS reader. How can I remove a specific item from an array in JavaScript? This was my approach to solving arrayAddition. There has to be a front of the line somewhere. // firstWord: a,all,b,ball,bas,base,cat,code,d,e,quit,z Thanks CodeiSir. Modified 1 year, . Have the function ArrayAddition(arr) take the array of numbers stored in arr and return the string true if any combination of numbers in the array (excluding the largest number) can be added up to equal the largest number in the array, otherwise return the string false. Your email address will not be published. For this reason I add the if(splitMainWordArray.length > 0) line. Asking for help, clarification, or responding to other answers. If you'd like a refresher on combinations (like I did), check out this great video walkthrough by Alvin from Coderbyte. Wait are you saying not all methods can take functions as parameters? The number 5 had to shift 4 positions towards the front of the line to be in its location, so person 5 made 4 bribes. I wonder if there's some article about this btw I know about callbacks and Higher Order functions but this seems different since it's in a methodEven though I know methods are also functionsSo I guess what I'm asking is how do I know when I can input functions as parameters(for methods) and is it possible for all methods? Note that the example [4, 6, 23, 10, 1, 3] => 4 + 6 + 10 + 3 = 23 is not just adding up the lowest to the biggest value to try and match it. The hunger level of all people ranges from 0 to 5. I recently completed a HackerRank code Challenge called New Year Chaos. If the element is excluded, the current target remains the same. A tag already exists with the provided branch name. This is what I am trying to figure out now. I am using recursion to solve this but I am getting 1 as the answer can someone please someone help to solve it? Hello "var largestNum=newArr.slice(-1);", "var largestNum=newArr.slice(-1);" is retourning an array wit the last element. This is illustrated in the recursive calls isSum(rest, target - first) || isSum(rest, target), For the base case, when we run out of elements to evaluate, we perform a check to see if the combination of elements subtracted from the current target equals 0. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. Content Discovery initiative April 13 update: Related questions using a Review our technical responses for the 2023 Developer Survey. I kept trying to use regex to solve the problem but lost time researching different ways I could use match() or replace(), but at the end of they day this is how I was more quickly able to solve the problem. Then, on line 8, the if statement evaluates whether the amount of bribes that person made is greater than 2, invalidating the array. Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide, This is happening because of the way recursion works. The format of the arr will be [N, h1, h2, h3, ] where N represents the number of sandwiches you have and the rest of the array will represent the hunger levels of different people. I constructed a helper method isSum and used recursion to consider each combination that includes or excludes the first element in the calculated sum (current target). In this video, Liz walks through a dynamic array problem and touches on how memory allocation \u0026 amortization works with array resizing. Disclaimer: This is not my challenge the original challenge is linked about. In the body of the nested for loop, an if statement evaluates whether the person number (value of Array element) is greater than the number of the next person in the queue. The variable wordToCompare refers to the word that I'll be comparing. Required fields are marked *. Thats it for your JavaScript. 1) First I start by grabbing the 2 elements which the problem refers to. Your program should return the two words that exist in the dictionary seperated by a comma. This is calculated by subtracting the current position in the queue (or the index of the Array plus 1. Once unpublished, all posts by krtb will become hidden and only accessible to themselves. Your loop just adds the numbers in increasing order. My Coderbyte solutions for the React challenges. The array will not be empty, Here, our target = 12 and sortedArr = [-1, 3, 5, 8]. try this: let strArr = ["codeaall", "a,all,b,ball,bas,base,cat,code,d,e,quit,z"] If you want the solution for PHP language, then you can use below code: leetcode.com/problems/word-break If nothing happens, download Xcode and try again. return true because 4 + 6 + 10 + 3 = 23. In the end the array will have nothing left in it so the length will be 0 and that is when we will end to loop execution. All we have left is to get the left side so we need to get all of the first items from each array. javascript coderbyte-js-solutions Updated on Dec 21, 2019 JavaScript xgravellx / javascript-algorithm-examples Star 2 Code Issues Pull requests In this repo, you can find examples to improve your Javascript Algorithm knowledge. Liz is kicking off a new series in this video where she focuses on dynamic arrays. let singleStrings = strArr[1].split(','); Last but not least, we return that finalArray that we have been building.

Coderbyte | Technical Assessments & Interviews Improve your coding skills. If true return true and finish the function. is not asking that all numbers need to add up to equal the largest num, but it is also possible to In the outermost scope, there is a variable named swaps on line 2, assigned the value of 0. swaps will act as the counter variable, incrementing by 1 each time a valid bribe and position swap is enacted. singleStrings.map(firstWord => dict[firstWord] = 1), singleStrings.map((firstWord) => { Default sort() sorts string while this one sorts number. sorts strings, but to sort numbers we include a function that finds which number is bigger. I wrote a solution that yielded the expected result when I ran the program in my terminal, but it did not pass tests on the HackerRank site. For example: strArr can be: ["hellocat", "apple,bat,cat,goodbye,hello,yellow,why"]. I am doing a challenge on Coderbyte and I would be grateful for any advice on my question: The challenge given to me: Your email address will not be published.

Loop (for each) over an array in JavaScript, tar command with and without --absolute-names option, Generic Doubly-Linked-Lists C implementation, What "benchmarks" means in "what are benchmarks for?". It would look something like, ['a', 'all', 'b', ]'. sign in This challenge required us to write a method that would take in an array and return true if some combination of elements in the given array could be added to equal the maximum value found in that array.

Person number 5 minus i + 1 (0 + 1, or 1, since this is the first iteration of the loop) is equal to 4. Are you sure you want to hide this comment? We need to do a while loop here because we dont know how many times the loop is going to have to go through to get the final answer. Thank you ^^. For example: if arr contains [4, 6, 23, 10, 1, 3] the output should return true because 4 + 6 + 10 + 3 = 23. rev2023.5.1.43404. on CodePen. Finally, so long as no invalid bribe was processed, the console.log() on line 17 prints to the terminal the minimum number of bribes that were required to produce the numerical order of the input array. Hey there. The challenge requires us to write a function foodDistribution which takes in arr of numbers. On line 17 the console.log() will print out the integer represented by swaps, unless the input array is invalid. Yes I understand that.
