NAME

6       Heap::Elem::NumRev - Reversed Numeric Heap Elements
7

SYNOPSIS

9         use Heap::Elem::NumRev( NumRElem );
10         use Heap::Fibonacci;
11
12         my $heap = Heap::Fibonacci->new;
13         my $elem;
14
15         foreach $i ( 1..100 ) {
16             $elem = NumRElem( $i );
17             $heap->add( $elem );
18         }
19
20         while( defined( $elem = $heap->extract_top ) ) {
21             print "Largest is ", $elem->val, "\n";
22         }
23

DESCRIPTION

25       Heap::Elem::NumRev is used to wrap numeric values into an element that
26       can be managed on a heap.  The top of the heap will have the largest
27       element still remaining.  (See Heap::Elem::Num if you want the heap to
28       always return the smallest element.)
29
30       The details of the Elem interface are described in Heap::Elem.
31
32       The details of using a Heap interface are described in Heap.
