The manager will print the cost of a removed process only if the ordinal number of the removed process is in the removal list. 

和这句：
The program prints on standard output the cost of each process that is removed, provided that the ordinal number of the remove request is in the list and the queue is not empty at that moment. If the queue is empty the program prints -1.

第一句话是以 ordinal number of the removed process
第二句是：   ordinal number of the remove request

设想以下情形 ，此时 queue为空，接收到 r 命令，
那么 ，这次 操作 按 第二句话 ，序数加 1 ，按第一句，就不加！！
