on CodePen. The industry's #1 code assessment platform for assessments, I like the tree diagram it made everything clicked for me. the integer assigned to that particular index. Andr Santiago. The challenge requires us to write a function foodDistribution which takes in arr of numbers. Thanks for keeping DEV Community safe. This is what I am trying to figure out now. if(arr.length === 0){ return target === 0 }. * 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. Are you sure you want to hide this comment? DEV Community 2016 - 2023. The array will not be empty, 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. Thanks. Hot Network Questions sorts strings, but to sort numbers we include a function that finds which number is bigger. 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). 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. 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. Coderbyte Array Addition 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. Does the 500-table limit still apply to the latest version of Cassandra? If krtb is not suspended, they can still re-publish their posts from their dashboard. Please help us improve Stack Overflow. Find centralized, trusted content and collaborate around the technologies you use most. *Array indices begin at 0) from the value of the current element being evaluated, or the identifying number of the person in that position. Thanks CodeiSir. topic, visit your repo's landing page and select "manage topics.". I had worked on a Medium level Coderbyte challenge for an interview, but was unable to make any decent headway at the time. Array Code Challenge Breakdown. The array will not be empty, will not contain all the same elements, and may contain negative numbers. 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. Also, there are MANY ways to solve this problem. Your goal is to minimize the hunger difference between each pair of people in the array using the sandwiches you have available. Add a description, image, and links to the Here, our target = 12 and sortedArr = [-1, 3, 5, 8].
