Intuition behind solution: Iterate through all numbers, simulating picking and not picking each element for the current subset. If you have already solved the current subproblem, return it's result. If any subset's sum multiplied by 2 ever equals the total of all numbers added together, return true. If the current subset's sum ever exceeds half of total or you've walked through all the numbers, return false. Otherwise, simulate taking and not taking the current number and store the result of the recursive calls (to ensure you only solve each subproblem once). Return your two recursive calls or'ed together.
