There is a grid with N rows and N columns of squares. Let (i,j) be the square at the i-th row from the top and the j-th column from the left.
These squares have to be painted in one of the C colors from Color 1 to Color C. Initially, (i,j) is painted in Color c_{i,j}.
We say the grid is a good grid when the following condition is met for all i,j,x,y satisfying 1 \leq i,j,x,y \leq N:
 - If (i+j) \% 3=(x+y) \% 3, the color of (i,j) and the color of (x,y) are the same.
 - If (i+j) \%  3 \neq (x+y) \% 3, the color of (i,j) and the color of (x,y) are different.
Here, X \% Y represents X modulo Y.
We will repaint zero or more squares so that the grid will be a good grid.
For a square, the wrongness when the color of the square is X before repainting and Y after repainting, is D_{X,Y}.
Find the minimum possible sum of the wrongness of all the squares.

-----Constraints-----
 - 1 \leq N \leq 500
 - 3 \leq C \leq 30
 - 1 \leq D_{i,j} \leq 1000 (i \neq j),D_{i,j}=0 (i=j)
 - 1 \leq c_{i,j} \leq C
 - All values in input are integers.

-----Input-----
Input is given from Standard Input in the following format:
N C
D_{1,1} ... D_{1,C}
:
D_{C,1} ... D_{C,C}
c_{1,1} ... c_{1,N}
:
c_{N,1} ... c_{N,N}

-----Output-----
If the minimum possible sum of the wrongness of all the squares is x, print x.

-----Sample Input-----
2 3
0 1 1
1 0 1
1 4 0
1 2
3 3

-----Sample Output-----
3

 - Repaint (1,1) to Color 2. The wrongness of (1,1) becomes D_{1,2}=1.
 - Repaint (1,2) to Color 3. The wrongness of (1,2) becomes D_{2,3}=1.
 - Repaint (2,2) to Color 1. The wrongness of (2,2) becomes D_{3,1}=1.
In this case, the sum of the wrongness of all the squares is 3.
Note that D_{i,j} \neq D_{j,i} is possible.
