Stuck midway in Sanskar

I have managed to generate all the possible subsets of the required sum. Here is an idea of where I am : Now,since I can't chose (1,2,3,5) and (1,2,8) together I need K disjoint subsets which I have been thinking on how to get.I initially thought of storing all the pairs in a double dimensional array and then bruteforcing random K subsets if it works out.But I thought I won't be able to pass within the given time limit so I didn't apply this logic. This situation is similar to the problem Exact Cover which is NP Complete I guess. Also,keep DP as far away as possible from the solution because don't know it much. Thanks!

People seem to have attempted the problem in a different manner than I have attempted. I want to know if there is a path which leads to the correct output from where I have left off my solution.

The link above is broken. However, I think you are doing something this way.

Here is the code till the point I've reached :

This gives me all subsets of the required sum but since we can't take both (1,2,3) and (1,5) I need to code it after this step to take into consideration only disjoint k subsets.
