解题思路:根据“幸运时刻”的定义分情况讨论,分别得到各种情况的个数,相加即可求解.,
00:00:00,00:11:00,00:22:00,00:33:00,00:44:00,00:55:00,有6个;
01:00:10,头尾不变中间为11,22,33,44,55,有6个;
02:00:20,头尾不变中间为11,22,33,44,55,有6个
03:00:30,头尾不变中间为11,22,33,44,55,有6个
04:00:40,头尾不变中间为11,22,33,44,55,有6个
05:00:50,头尾不变中间为11,22,33,44,55,有6个
10:00:01,头尾不变中间为11,22,33,44,55,有6个
11:00:11,头尾不变中间为11,22,33,44,55,有6个
12:00:21,头尾不变中间为11,22,33,44,55,有6个
