Priority Queue (Priority Queue)
11 USD This is a regular line with the operations of setting in order (enqueue) and dequeue (dequeue), but it also has the number of points (score) for each element, and during the call of removal from the line the item with the highest score returns (or the first inserted of several elements with the highest score).
The teams meet the operations of the order:
ENQUEUE - sets the item with the given name and score.
DEQUEUE - removes the element at the beginning of the line and pulls it out to the conclusion.
DONE is the last team after which the program can be completed.

The Input:
The Enquire a 5
The Enquire B9
Decoured
The Enquire C 12
Decoured
Decoured
Done
The output: B 9

It should be guaranteed that the removal from a line (DEQUEUE) will not be caused by a empty line, that the element's name does not contain a gap symbol and that the score is whole numbers.
