参考代码:

count,day = map(int,input().split())

matrix = [[0]*9 for _ in range(9)]

dx = [-1,-1,-1,0,0,1,1,1]

dy = [-1,0,1,-1,1,-1,0,1]

matrix[4][4] = count

for d in range(day):

    tmpm = [[0]*9 for _ in range(9)]

    for i in range(9):

        for j in range(9):

            if matrix[i][j] != 0:

                tmpm[i][j] += matrix[i][j]*2

                for k in range(8):

                    tx = i +dx[k]

                    ty = j +dy[k]

                    if 0<=tx<=8 and 0<=ty<=8:

                        tmpm[tx][ty] += matrix[i][j]

    matrix = tmpm

for i in range(9):

    for j in range(9):

        matrix[i][j] = str(matrix[i][j])

for i in range(9):

    print(f"{' '.join(matrix[i])}")
