Answer 1

I have been staring at this for several minutes and I can't figure out what your train of thought is for thinking that it would work. You are permanently removing several members of the input list before exploring every possible subset that they could participate in.

Try working out the solution you intend in pseudo-code and see if you can see the problem without the stl interfering.
