2017杭电计算机研究生复试笔试编程题第二题（JAVA）

输入N个员工，每个员工输出ID号，上班时间，下班时间，
第一行输出 最早去的员工的ID和上班时间
第二行输出 最迟走的员工的ID和下班时间
第三行输出 工作最久的员工的ID和上班时间
(数据瞎编的)
sample input：
ID100001， 07:00:00 17:00:00
ID100002， 08:00:00 18:00:00
ID100003， 09:00:00 21:00:00
sample out:
OPEN:ID100001,  07:00:00
CLOSE:ID100003,  21:00:00

STAR:ID100003,  12:00:00
