题目描述

Suppose a bank has N windows open for service.  There is a yellow line
in front of the windows which devides the waiting area into two parts.
The rules for the customers to wait in line are: 



The space inside the yellow line in front of each window is enough
  to contain a line with M customers.  Hence when all the N lines are
  full, all the customers after (and including) the (NM+1)st one will
  have to wait in a line behind the yellow line.

Each customer will choose the shortest line to wait in when crossing
  the yellow line.  If there are two or more lines with the same length,
  the customer will always choose the window with the smallest number.

Customer[i] will take T[i] minutes to have his/her transaction processed.

The first N customers are assumed to be served at 8:00am. 



Now given the processing time of each customer, you are supposed to tell
the exact time at which a customer has his/her business done.

For example, suppose that a bank has 2 windows and each window may have
2 custmers waiting inside the yellow line.  There are 5 customers
waiting with transactions taking 1, 2, 6, 4 and 3 minutes, respectively.
At 08:00 in the morning, customer1
 is served at window1
 while customer2
 is served at window2
.  Customer3
 will wait in front of window1
 and customer4
 will wait in front of window2
.  Customer5
 will wait behind the yellow line.

At 08:01, customer1
 is done and customer5
 enters the line in front of window1
 since that line seems shorter now.  Customer2
 will leave at 08:02, customer4
 at 08:06, customer3
 at 08:07, and finally customer5
 at 08:10.

输入描述:

Each input file contains one test case.  Each case starts with a line containing 4 positive integers: N (<=20, number of windows), M (<=10, the maximum capacity of each line inside the yellow line), K (<=1000, number of customers), and Q (<=1000, number of customer queries).
The next line contains K positive integers, which are the processing time of the K customers.
The last line contains Q positive integers, which represent the customers who are asking about the time they can have their transactions done.  The customers are numbered from 1 to K.

输出描述:

For each of the Q customers, print in one line the time at which his/her transaction is finished, in the format HH:MM where HH is in [08, 17] and MM is in [00, 59].  Note that since the bank is closed everyday after 17:00, for those customers who cannot be served before 17:00, you must output "Sorry" instead.
