PID = 1, 3033 There are n kinds of shoes, m yuan in the hand, and N kinds of shoes belong to k brands, (1 Train of Thought: the variant of the backpack problem divides the items to be loaded into several categories, and there are limits on the selection of each item (generally choose at least one or more, because all items are grouped, the results of the previous I-1 class subcontracting will be processed

in group I will be selected. The T-pieces may not be cost-effective and will not be loaded. At the same time, it is not cost-effective to install other parts in the same group. To solve this problem, first pre-install one of the cheapest ones, that is, the second row mentioned above is updated to "the cheapest shoes in group I are required ", this ensures at least one piece in each group. If the group I in the official answer should only have one, and it is not the cheapest, the transfer method
