I've seen versions of this question for other languages, but not for JS.  Is it possible to do this recursively in one function?  I understand that I need to take the first element in the string, and then append it to each solution to the recur...
Requirement: Algorithm to generate all possible combinations of a set , without duplicates , or recursively calling function to return results.  The majority , if not all of the Answers provided at Permutations in JavaScript? recursively call a fun...
It must be noted here that I performed the mathematics by hand on paper to derive the foregoing proofs. I am not sure if the proofs would have become apparent by solely using the medium of the modern computer.  The definition of "efficiency"...
I have an 'item' object in JavaScript, and the item can have settings like color, size, etc.  I need to get all possible combinations in an array.  So lets say we have an item that looks like this:  var newItem = {     name: 'new item'...
So given input = [1, 2, 3] and k=2 this would return:  1 2 1 3 2 1 2 3 3 1 3 2   This is the closest to what I am looking for, but not quite: http://algorithms.tutorialhorizon.com/print-all-combinations-of-subset-of-size-k-from-given-array/    functi...
var a = [1,3,6,10,-1]; function combinations(array, n) { }  combinations(a, 9) // should return... [[1], [3], [6], [-1], [1,3], [1,6], [1,-1], [3,6], [3,-1], [6, -1], [10, -1], [1,3,-1], [3,6,-1], [1,6,-1], [1,3,6,-1]]   maybe i'm missing some co...
I have the array [1, 2, 4] and I want to make 4; I want it to return [4], not [[1,1,1,1], [1,1,2], [2,2], [4]], I was previously doing this but I started to run out of memory when running this on a small server. I had to let the whole function run th...
Let's says I've an array['Alex', 'Sam', 'Robert']  I'd like to combine them something like:  Take first array[0] and append with array[2] which will be AlexRobert  first letter of array[0] which is A and append wit...
Little challenge.    Goal (nodeJS, loop is an * interator function using "yield" strategy)  var str; var minChars = 1; var maxChars = 10; for (str of loop('abcdefghijklmnopqrstuvwxyz',minChars,maxChars)) {     console.log(str); }...
So I have this code now, and in input I have in ascending order my name's letters "ahimrsu". I need to show up the right number for "mariush" from all combinations which should to be 2170. For now it only show ahimrsu, ahimrus, ah...
