- Return:
- binary list of the positions of the elements included in the subset sum or 0 if no solution exists
- Note:
- This will return the first solution of the ssk-problem, given be the smallest binary encoding. It wont return several solutions if they exist
Example:
| | LIB "crypto.lib";
list h=1,4,7,32;
subset_sum01(h,20);
==> 0
subset_sum01(h,11);
==> [1]:
==> 0
==> [2]:
==> 1
==> [3]:
==> 1
==> [4]:
==> 0
subset_sum01(h,33);
==> [1]:
==> 1
