Thanks CodeiSir. Each person in the queue is sequentially assigned an integer, starting from 1 at the beginning of the queue. 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? A repo where you can find important questions of DS-ALGO ,REACT and SQL Queries from Codeybyte . If nothing happens, download Xcode and try again.

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. In this example, the first element can be split into two words: hello and cat because both of those words are in the dictionary. 7) There was a case where I was getting base from baseball, but I needed to place it inside an array to then run a .join() and .toString() in order for ballbase to equal baseball. return true because 4 + 6 + 10 + 3 = 23. Refresh the page, check Medium 's site status, or find something interesting to read. * 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. 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. Also, there are MANY ways to solve this problem.

The first few lines are the same as the first solution, The next part is very similar to the first solution and you can actually switch our the first for loop for this but we are going to use .map() to get the last number from each array (row) and push it into the finalArray, This is where it gets really interesting. Here the input is an array of integers finally the array should be reduced to the size of one element by finding the absolute difference between two elements. Today we are borrowing a challenge from Codewars! Thanks. This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository.
