Given an array and group them as a possible sum.
Input Only this array : [1,2,3,4,5]
Output : {[5,1] [4,2]} {[3,2] [4,1]}
Is there any way to solve this problem without using nesting of for loop?

Recursive function with a single loop. – olegarch Sep 18 '20 at 13:04

1What is this `possible sum` value? Can this be anything? – Phenomenal One Sep 18 '20 at 13:06

And in the second example, why wasn't the grouping `[5]` included in groups that sum to 5? – btilly Sep 18 '20 at 18:04
