HDU 5437 Alisha’s Party（优先队列模拟）

思路：题目比较好懂的模拟题，用一个优先队列即可

          模拟的时候要注意最后还会再开一次门，把剩下的人全部放进来，开门的时间并不一定是递增的，要自己排个序，还有就是要注意开门的时候是2 5这种数据，就是到第二个人到了开门，然后可以放5个人进来，这样不处理的话会RE

Description

, and all of them will come at a different time. Because the lobby is not large enough, Alisha can only let a few people in at a time. She decides to let the person whose gift has the highest value enter first. 

Each time when Alisha opens the door, she can decide to let 

 people enter her castle. If there are less than 

 people in the lobby, then all of them would enter. And after all of her friends has arrived, Alisha will open the door again and this time every friend who has not entered yet would enter. 

If there are two friends who bring gifts of the same value, then the one who comes first should enter first. Given a query 

 Please tell Alisha who the

Each of the following 

 lines contains two integers 

 and 

 separated by a blank. The door will open right after the

 friends enter her castle. 

The last line of each test case will contain 

 numbers 

 separated by a space, which means Alisha wants to know who are the 

 friends to enter her castle. 

Note: there will be at most two test cases containing

Output

For each test case, output the corresponding name of Alisha’s query, separated by a space.
