【題解】ZeroJudge e974: 2. 座位安排 (Seats)

R, C, N = map(int, input().split())
seat = []
for i in range(R):
    seat.append([str(i*C+1+j) for j in range(C)])

for i in range(2, N+1):

        # 雙數週時所有人往右橫移一個座位，原本最右邊的人則換到最左邊
        for j in range(R):
            seat[j] = [seat[j][-1]] + seat[j][:-1]
    else:

        #tmp = copy.deepcopy(seat[-1])
        tmp = seat[-1]
        for j in range(R-1, 0, -1):
