write a go solution for Description:
There are n players sitting at the card table. Each player has a favorite number. The favorite number of the j-th player is f_j.

There are k*n cards on the table. Each card contains a single integer: the i-th card contains number c_i. Also, you are given a sequence h_1,h_2,...,h_k. Its meaning will be explained below.

The players have to distribute all the cards in such a way that each of them will hold exactly k cards. After all the cards are distributed, each player counts the number of cards he has that contains his favorite number. The joy level of a player equals h_t if the player holds t cards containing his favorite number. If a player gets no cards with his favorite number (i.e., t=0), his joy level is 0.

Print the maximum possible total joy levels of the players after the cards are distributed. Note that the sequence h_1,...,h_k is the same for all the players.

Input Format:
The first line of input contains two integers n and k (1<=n<=500,1<=k<=10) — the number of players and the number of cards each player will get.

The second line contains k*n integers c_1,c_2,...,c_k*n (1<=c_i<=10^5) — the numbers written on the cards.

The third line contains n integers f_1,f_2,...,f_n (1<=f_j<=10^5) — the favorite numbers of the players.

The fourth line contains k integers h_1,h_2,...,h_k (1<=h_t<=10^5), where h_t is the joy level of a player if he gets exactly t cards with his favorite number written on them. It is guaranteed that the condition h_t-1<h_t holds for each tin[2..k].

Output Format:
Print one integer — the maximum possible total joy levels of the players among all possible card distributions.

Note:
In the first example, one possible optimal card distribution is the following:

- Player 1 gets cards with numbers [1,3,8];
- Player 2 gets cards with numbers [2,2,8];
- Player 3 gets cards with numbers [2,2,8];
- Player 4 gets cards with numbers [5,5,5].

Thus, the answer is 2+6+6+7=21.

In the second example, no player can get a card with his favorite number. Thus, the answer is 0.. Output only the code with no comments, explanation, or additional text.
