See the assignment turn-in page (last modified on 11 September 2001) for instructions on turning in your assignment.

vector<vector<unsigned> > group(const vector<unsigned> &);

that accepts a vector of positive integers and returns a vector of integer vectors such that

1. The number of integer vectors returned is as small as possible, but is larger than 1.

2. The sum of the integers in each integer vector returned is the same as the sum of the integers in any other integer vector returned.

3. All the integers in the output vector appear in the input vector and vice versa.

You can test your procedure by compiling it with the file

and running the resulting executable.
