The final answer I get from our example string was base, ball. Array Code Challenge Breakdown. An Analysis and Solution Expressed in Hot Network Questions 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. Welcome back to Code Review, a series of real coding interview challenges released every Thursday brought to you by Coderbyte, an interview prep platform that's helped over 500,000 developers land their next role. I built this out in a CodePen if you want to play around with it. Your program should return the two words that exist in the dictionary separated by a comma. For this week's challenge, we're focusing on a Javascript interview question asked during a Microsoft interview which covers relevant real-world topics. Once suspended, coderbyte will not be able to comment or publish posts until their suspension is removed. console.log(firstWord, splitMainWordArray, 'splitMainWordArray'), This is not correct solution as it's will still return the hello , cat if pass this In the meantime, if you're looking for more interview prep or just interested in diving deeper into data structures and algorithms, check out Coderbyte's challenge library and our Youtube channel. Thanks for keeping DEV Community safe. It required me to test and check my assumptions about the data being processed, and understand the mechanics of the scenario in order to most effectively write a function that delivered the necessary result. What's the cheapest way to buy out a sibling's share of our parents house if I have no cash and want to pay less than the appraised value? * Create a recursion function that checks if the numbers add up to the largest number, and if not, check that if some numbers in array are subtracted from the largest num they are equal to the largest number.

Asking for help, clarification, or responding to other answers. The conditions of the nested for loop state that the counter variable j will begin at the index determined by maxAdvance and increment (i++) by 1 as long as j is less than the current index (i) of the outer for loop. Test if the remaining sum is zero, if so the result is achieved and return, Test, if the value is smaller or equal the remaining sum and the result of the call of. What were the most popular text editors for MS-DOS in the 1980s? // First Element, with single string Your email address will not be published. now we need to get the last array and reverse it (bottom line) if you are unfamiliar with .reverse() check out this MDN page before continuing.

GitHub - ZLester/Coderbyte-Solutions: Step-by-step JavaScript Coderbyte Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. Refresh the page, check Medium 's site status, or find something interesting to read. Have the function ArrayChallenge(strArr) read the array of strings stored in strArr, which will contain 2 elements: the first element will be a sequence of characters, and the second element will be a long string of comma-separated words, in alphabetical order, that represents a dictionary of some arbitrary length. "var largestNum=newArr.slice(-1);", "var largestNum=newArr.slice(-1);" is retourning an array wit the last element. Here is what you can do to flag coderbyte: coderbyte consistently posts content that violates DEV Community's I looked up info on it but instead found this: Thank you Nina for taking the time to create a solution and writing out the steps, but I wasn't looking for a new solution.

There was a problem preparing your codespace, please try again. If you are just joining us, be sure to check out last week's article where we introduced CodeReview and relaunched the series with our first challenge: an interview question asked at Amazon. Code Interview - Coderbyte - Array Addition - Code challenge The arr represents the hunger level of different people ranging from 0 to 5 (where 0 means not hungry at all, 5 means very hungry). The problem statement describes a queue of people waiting for a ride. Required fields are marked *. 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). you will notice that I am giving it an empty array just in case there is no last array or nothing is there the .reverse will error if it doesnt have at least an empty array so we are giving it an empty array if array doesnt have something to pop. 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. For example: strArr can be: ["hellocat", "apple, bat,cat,goodbye,hello,yellow,why"]. You signed in with another tab or window. Problem: Have the function WordSplit(strArr) read the array of strings stored in strArr, which will contain 2 elements: the first element will be a sequence of characters, and the second element will be a long string of comma-seperated words, in alphabetical order, that represents a dictionary of some arbitrary length. Your goal is to minimize the hunger difference between each pair of people in the array using the sandwiches you have available. let singleStrings = strArr[1].split(','); let dict = {}; Your program should return the two words that exist in the dictionary seperated by a comma. Array Code Challenge Breakdown. 8) If these 2 conjoined words are equal to our first string, baseball, or if reversed they're equal, we then have our answer that we concatenate and return outside of all the loops by assigning it to the emprty answerWords variable we created at the start. Particularly Bamar's suggestion of skipping over the problems. However, upon switching, both persons retain their sequential identifier, i.e. let splitMainWordArray = wordToCompare.split(firstWord) Default sort() sorts string while this one sorts number. Made with love and Ruby on Rails. on CodePen. Feel free to contribute your own solutions or improve upon the ones I've created! A possible example of a solution for the problem. Andr Santiago. It never tries combinations that skip some of the numbers. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. What does "use strict" do in JavaScript, and what is the reasoning behind it? I found an article or two that presented the problem and offered a solution, but I was not able to find an article which expressed the solution in JavaScript, nor explained the code mechanics as thoroughly as I hoped. There has to be a front of the line somewhere. Which is why I then write if(joinedWord === wordToCompare || reversedWord === wordToCompare). Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. arr will also contain N sandwiches to give out which will range from 1 to 20. Now we need to add a while loop. If the original position of the current element (person) minus 2 (spaces) is greater than 0, then the value of maxAdvance is the current element (q[i]) minus 2. Array Challenge ** Have the function ArrayChallenge (strArr) read the array of strings stored in strArr, which will contain 2 elements: the first element will be a sequence of characters, and the second element will be a long string of comma-separated words, in alphabetical order, that represents a dictionary of some arbitrary length. 's which even added a frontend visualization for his solution. I decided to write such an article. coderbyte-js-solutions Within the scope of the for loop, there are two variables declared, an if statement, and a nested for loop. any combination of numbers in the array can be added up to equal the Thanks for contributing an answer to Stack Overflow! try this: let strArr = ["codeaall", "a,all,b,ball,bas,base,cat,code,d,e,quit,z"] The array will not be empty, its even simpler than the above AppDev4Tech Application Development for Tech. Once suspended, krtb will not be able to comment or publish posts until their suspension is removed. I practice Coderbyte challenge almost every day and share it here. How do I stop the Flickering on Mode 13h? Step-by-step JavaScript Coderbyte problem solutions.

How do I check if an array includes a value in JavaScript? DEV Community 2016 - 2023. In this example, the first element can be split into two words: hello and cat because both of those words are in the dictionary. Vector Projections/Dot Product properties. Unflagging krtb will restore default visibility to their posts. Over the past week, we saw some interesting approaches to the problem including @dbenchi The challenge given to me: "Using the JavaScript language, have the function ArrayAdditionI (arr) take the array of numbers stored in arr and return the string true if any combination of numbers in the array can be added up to equal the largest number in the array, otherwise return the string false. * the sort() method can take a parameter to further expand it's purpose. This was my approach to solving arrayAddition. Please leave your solutions that you came up with in the comments section. The first element itself will never exist in the dictionary as a real word. Use Git or checkout with SVN using the web URL. For this reason I add the if(splitMainWordArray.length > 0) line. You may not have to give out all, or even any, of your sandwiches to produce a minimized difference.
