A KitKat is a candy bar that can be split into two equal sized pieces. One day while Christmas shopping, Roger stumbles upon the legendary -kat: a KitKat that can be split into equally sized pieces, with the piece having sweetness . Roger wishes to split the pieces into two disjoint non-empty subsets to share with his two friends such that the total sweetness of the two subsets has the smallest possible non-negative difference. Note that the two subsets do not need to contain all elements; Roger will eat any pieces his friends do not get. Help Roger split the -kat!

Note that the judge will accept any valid solution.

Hint: It is recommended Python users use PyPy instead.
