The PriorityQueue class

(No version information available, might only be in Git)

はじめに

A PriorityQueue is very similar to a Queue. Values are pushed into the queue with an assigned priority, and the value with the highest priority will always be at the front of the queue.

Implemented using a max heap.

注意:

"First in, first out" ordering is preserved for values with the same priority.

注意:

Iterating over a PriorityQueue is destructive, equivalent to successive pop operations until the queue is empty.
