    def sumevennotdivisibleby3(A, B): def sumofarithmeticsequence(start, end, step): count = (end - start) // step + 1 return count * (start + (count - 1) * step // 2)

    # Tìm tổng các số chẵn từ A+1 đến B-1
start = (A // 2 + 1) * 2
end = (B - 1) // 2 * 2
if start > end:
    return 0
total_sum_even = sum_of_arithmetic_sequence(start, end, 2)

# Tìm tổng các số chẵn chia hết cho 6 từ A+1 đến B-1
start = ((A // 6) + 1) * 6
end = (B - 1) // 6 * 6
if start > end:
    total_sum_six = 0
else:
    total_sum_six = sum_of_arithmetic_sequence(start, end, 6)

return total_sum_even - total_sum_six

    Đọc đầu vào

    A = int(input()) B = int(input())

    Tính tổng các số X thỏa mãn điều kiện

    result = sumevennotdivisibleby_3(A, B)

    In kết quả

    print(result)
