Description

A priority queue is a handy data structure with many uses. From graph search algorithms to simple job queues, having this in your toolbelt will help to give you a solid foundation.

Features

• Simple to use and understand.
• Creates a single PriorityQueue constructor.
• Instantiate via PriorityQueue() or new PriorityQueue()
• Offers both highest first and lowest first ordering.
• Test suite included.

The default is highest priority first, but when doing something like A* you want lowest priority first... it handles it: queue = PriorityQueue({low: true}); Boom!

Example Usage

# Highest priority first
queue = PriorityQueue()

queue.push("b", 5)
queue.push("a", 10)

queue.pop() # => "a"
queue.pop() # => "b"

# Lowest priority first
queue = PriorityQueue
  low: true

queue.push("x", 5)
queue.push("y", 10)

queue.pop() # => "x"
queue.pop() # => "y"
