hi all,
I am having problems printing this doubly list. the bug statment prints the
expacted so I think I have the list setup right, but I cant get this list to
print in reverse... any ideas ??
Thanx in Advance
#!/usr/bin/perl -w
$debug=1;
for($i=1;$i<10;$i++){
$list = {value=>$i,prev=>$list,next=>${prev} };
print "prev=$prev\tlist=$list\n" if( $debug);
$prev= $list;
}
$iterator = $list;
while($iterator){
print "$iterator->{value} ";
$iterator = $iterator->{next};
#$iterator=$iterator->{prev};
}
print "\n";
print "In reverse \n";
$iterator = $prev;
while($iterator){
print "$iterator->{value} ";
$iterator= $iterator->{prev};
}
