编程题：Big Ben

There is a lovely big Ben. It rings the bell every day to make everyone pay attention to the time to rest. However, because Ben Zhong doesn't work and rest regularly, he doesn't ring the bell regularly.
Generally, the number of times to ring the bell is determined according to the time. At the hour, the number of "Dang" that rings the bell is equal to the number of hours; If it is past the hour, ring the bell one more "dang".
In addition, although there are 24 hours in a day, Big Ben only rings the bell in the second half of the day.
For example, The sound of the 23:00 bell is "DangDangDangDangDangDangDangDangDangDangDang". At 23:01, it will be "DangDangDangDangDangDangDangDangDangDangDangDang".
From 00:00 at midnight to 12:00 at noon (including the starting and ending time), Big Ben does not ring.
