+cost | coins
+1      | 1
+2      | 1 + cost(1)
+3      | 1 + cost(2) OR 3 (we pick 3)
+4      | 1 + cost(3) OR 4 (we pick 4)
+5      | 1 + cost(4) OR 3 + cost(2) OR 4 + cost(1) (we pick the last or the first)
+6      | 1 + cost(5) OR 3 + cost(3) OR 4 + cost(2) (we pick 3 + cost(3), because that's fewer coins than the other options)
