规则： 1、Mon、Tue、Wed...表示一周的某一天； 2、00:02:00-00:03:00表示一天之内的某一时间段； 3、SunThu|00:02:00-00:03:00表示某天(和某天)的某一时间段； 4、SunThu|00:02:00-00:03:00,Mon|16:59:00-20:00:00表示某天(和某天)的某一时间段和表示某天(和某天)的某一时间段，一组内可包括一至七天，一组内只能包括一个时间段。 基于以上规则，使用C语言实现检查当前时间点是否在规则规定的时间段内，使用方式： ./time_range_check "SunThu|00:02:00-00:03:00,Mon|16:59:00-20:00:00,FriSun|00:02:00-23:30:59,Sun|15:59:00-20:00:00" 规则格式正确 当前时间点在规则内
