Konkurrence Instruktioner

- an array of N non-negative unique integers
- a sum non-negative integer S

Write javascript (ES6, e.g., Node.js) function that checks if any subset of the N integers can sum to S (the subsets could be from length 1 to N, we don't care about the length, just the sum), output an array:
- empty if no subset of the N integers can sum to S
- otherwise, each element of the array is another array with a subset that sums to S, thus the elements would be all the different ways we can form subsets of N that sum to S ; do not duplicate the elements of the array, and also do not miss any subset that sums to S. How about subsets [ a b ] and [ b a ] ? To avoid confusion, each element should be in numerical order, so only one of [ a b ] and [ b a ] would be included

console.log the array

e.g., N is 5, the array is [ 3 5 8 2 6 ] , S = 11
Answer: [ [ 2 3 6 ] , [ 3 8 ] , [ 5 6 ] ]

I will test on some sample inputs. For selecting a contest winner:
a) Correctness (not crashing or other bugs, and giving desired, correct answers) is 1st priority. Winner would be selected from the correct answers for my sample inputs
b) If more than one are correct, tie breakers:
- elegance
- don't use libraries if possible
- performance - very slow running code is less preferred
- timeliness - who submits earlier - only if all else is equal

    Should i consider the input array as sorted? Or the numbers are in random order?
