4) Is there likely to be a significantly more efficient solution
to problem 3? Why or why not. Hint: This problem is very similar to
the SOS problem defined in Theory of Computation,
posting question 3 for efernce :
3)3) Does the following set have a subset that adds up to 0?
{20, 27, -3, -1, 2, 7, 13, -44, -3, -5, 4} Suggestion: There are
2048 subsets of this set and you cannot check them all by hand. Use
the Haskell Stdm library’s `powerset` function to get all subsets.
Then see if one of them satisfies the requirement that the sum of
all its elements is 0.
