B'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 cdot 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. 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 cdot n integers c_1, c_2, ... , c_{k cdot 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 t in [2..k] . Print one integer -- the maximum possible total joy levels of the players among all possible card distributions. In the first example, one possible optimal card distribution is the following: Thus, the answer is 2 + 6 + 6 + 7 = 21 .'...
