Given an array of integers, give all possible ways the integers can be added to a certain value.

• The output should be a list of lists containing all correct sums.
• The resulting list should not contain duplicates.
• The resulting sums should be in increasing order (i.e. sorted)

Example:

Give sums to 12:
   ✓ [1,2,3,3,5,7] => [5, 7], [2, 3, 7], [1, 3, 3, 5]
   X [1,2,3,3,5,7] => [7, 5], [2, 3, 7], [1, 3, 3, 5]
   X [1,2,3,3,5,7] => [7, 5], [2, 3, 7], [2, 3, 7], [1, 3, 3, 5]
