NAME
Heap::Elem::StrRev - Perl extension for Reversed String
Heap Elements
SYNOPSIS
use Heap::Elem::StrRev( StrRElem );
use Heap::Fibonacci;
my $heap = Heap::Fibonacci->new;
my $elem;
foreach $i ( 'aa'..'bz' ) {
$elem = StrRElem( $i );
$heap->add( $elem );
}
while( defined( $elem = $heap->extract_minimum ) ) {
print "Largest is ", $elem->val, "0;
}
DESCRIPTION
Heap::Elem::StrRev is used to wrap string values into an
element that can be managed on a heap. The top of the
heap will have the largest element still remaining. (See
Heap::Elem::Str if you want the heap to always return the
smallest element.)
The details of the Elem interface are described in
Heap::Elem.
The details of using a Heap interface are described in
Heap.
