Your goal is to minimize the hunger difference between each pair of people in the array using the sandwiches you have available. I am doing a challenge on Coderbyte and I would be grateful for any advice on my question: The challenge given to me: .sort() was not working. Usually it only I had worked on a Medium level Coderbyte challenge for an interview, but was unable to make any decent headway at the time. The conditional operator essentially makes sure the placeholder cannot become negative, i.e. Vector Projections/Dot Product properties. The people in the queue are represented as elements. Once unpublished, this post will become invisible to the public and only accessible to Kurt Bauer. 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.

Did the Golden Gate Bridge 'flatten' under the weight of 300,000 people in 1987? 247 Followers. function WordSplit(){ Which is why I then write if(joinedWord === wordToCompare || reversedWord === wordToCompare). 6) I add a second map function, splitMainWordArray.map, to loop over the first arrays I got when I wrote let splitMainWordArray = wordToCompare.split(firstWord). rev2023.5.1.43404. Did the drapes in old theatres actually say "ASBESTOS" on them? Also, there are MANY ways to solve this problem. To learn more, see our tips on writing great answers. A tag already exists with the provided branch name. 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.

Dan Romans 92 Followers // fullStackWebDeveloper, # software_engineer, Musician & Woodworker What positional accuracy (ie, arc seconds) is necessary to view Saturn, Uranus, beyond? Here is what you can do to flag krtb: krtb consistently posts content that violates DEV Community's Try it free. The value of maxAdvance is determined by the evaluation of a conditional operator. The first variable, on line 5, is named bribes, and represents the number of bribes the current person (current element) enacted. It would look something like, ['a', 'all', 'b', ]'. Once unpublished, all posts by coderbyte will become hidden and only accessible to themselves. Thanks for keeping DEV Community safe. * 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. No description, website, or topics provided. Are you sure you want to create this branch? I now have to iterate over that array to check each string and see if it can be found in the original string in any way, like baseball for example. You may not have to give out all, or even any, of your sandwiches to produce a minimized difference. In my experience I have found that recursion is difficult to grasp but the solution it provides are very elegant. Today we are borrowing a challenge from Codewars! How do I determine whether an array contains a particular value in Java? 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. Can you offer an example? Given an n x n array, return the array elements arranged from outermost elements to the middle element, traveling clockwise. The problem is that I then get an array of string elements. * Sort the array and remove the largest number to be used for recursion later. Please leave your solutions that you came up with in the comments section. And the variable stringDictionary represents the dictionary of words string that I was provided. If you are not familiar with them check out this MDN page. Please help us improve Stack Overflow. Later on we can set our answer to equal this variable to return our answer out of the loops. We're a place where coders share, stay up-to-date and grow their careers. The queue is represented as an Array. // firstWord: a,all,b,ball,bas,base,cat,code,d,e,quit,z sorts strings, but to sort numbers we include a function that finds which number is bigger. * First get the largest number. take the array of numbers stored in arr and return the string true if Just kidding :) We'd love to see the approaches you come up with. I really like your challenges. What is the symbol (which looks similar to an equals sign) called? In this example, the firs element can be split into two words: hello and cat because both of those words are in the dictionary. How can I remove a specific item from an array in JavaScript? Built on Forem the open source software that powers DEV and other inclusive communities. Hey Parth thank you. let splitMainWordArray = wordToCompare.split(firstWord) For example: in the second input example on line 28, the first element (q[0]) value is 5. A possible example of a solution for the problem. 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. Thanks for keeping DEV Community safe. With you every step of your journey. This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository.

If you would like to get the challenge emailed to you every day in morning and a notification when the solution is posted subscribe below, Privacy PolicyDisclaimerTerms and Conditions, //loop through the parent array - while array still has items in it, //get the first row (first array in the array), //get the items at the end of each array (right side), //get the bottom row from end to front (bottom row reversed), //get the items at the beginning of the arrays (left side), //reverse the parent array and each array in the parent array. Today we are borrowing a challenge from Codewars! This allows me to try and see if I can split() my wordToCompare in order to see if I can split it into two words. Otherwise, the value of maxAdvance is 0. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. But I am pretty sure the Algorithm is wrong - but I think this is up to you. WordSplit by Kurt (@kurtbauer) This is what I am trying to figure out now. What is the symbol (which looks similar to an equals sign) called? These are a few answers that I wrote or find clever with explanations of why/how they work, TLDR: explanation of best solution at the bottom of the post and actual solutions at the bottom of each section. After finishing all of Coderbyte's easy and medium challenges, I thought it might be useful for both myself (and anyone else learning javascript by completing these challenges) to go back through each challenge with cleaner/well-commented code. 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.

Connect and share knowledge within a single location that is structured and easy to search. For further actions, you may consider blocking this person and/or reporting abuse. All we have left is to get the left side so we need to get all of the first items from each array. This Week's Challenge. Here, our target = 12 and sortedArr = [-1, 3, 5, 8]. To learn more, see our tips on writing great answers. For example: strArr can be: ["hellocat", "apple, bat,cat,goodbye,hello,yellow,why"]. the problem, you have is, you loop only once over the items and try to get a result which at least requires to loop over the rest from the array again and again until a solution is found. We are going to make the loop while array has a length as we will be removing items from each array as we loop. DEV Community 2016 - 2023. He also rips off an arm to use as a sword. In my solution, I first sorted the array in ascending order and then used pop() in order to mutate the array and remove the target.
