  If this question is widely searched, the space demand is very large and the space is insufficient. Deep Search is difficult to control and easily falls into an endless loop. At this time, we need to use the iterative deep search method. The

At the beginning, it was easy to think of James another two types of packages: Money and points. At that time, I had to worry about how to use the free k items. For a long time, if you take the most expensive item, the two prices may conflict. If
