A package. Implementation follows Fredman and Tarjan's 1987 paper.

 

import "fmt"

}

f(h.Node, "")

A demonstration:

 

import (

h.Delete(x)

h.Vis()

{{out}}

<pre>

{{trans|Python}}

 

export FNode, FibonacciHeap, insert, extractmin, findmin, decreasekey, delete!

print(h3)

println("The minimum of h3 is now: ", Minimum(h3).value

<pre>

Made heap 1:
