Re: trying to implement hash table. and getting lots of difficulties. plz help me out..........

Your structure and logic is much more complicated than necessary, but I have preserved it, and made a few corrections. Try this one:

use strict;
use warnings;
use Data::Dumper;

my %ex = (
37 => "p" , 41 => "t",
23 => "s" , 52 => "m",
44 => "a" , 65 => "q",
26 => "d" , 88 => "o" , 
99 => "g" , 100 => "l" , 101 => "f" , 201 => "i"
); 
my @buckets = ( [],[],[],[],[],[],[],[],[],[] );
sub perlhash
{
  my $k = shift @_;
  my $hash = 0;
  $hash = ($k % 10);
return $hash;
}


while(my ($k , $v) = each(%ex)) {
  my $hash = perlhash($k);
  my $ch = $buckets[$hash];
  my $entry;
  # print Dumper $buckets[$hash];
  if(scalar @{$ch} == 0){
     $entry = {$k => $v};
  }else{
    $entry = $ch->[0];
    $entry->{$k} = $v ;
    next;
  }
   push @$ch , $entry;
}
print Dumper \@buckets;

print "enter a key u want to search";
chomp(my $k = <STDIN>);
my $h = perlhash($k);
print "The Key in Slot $h is " .  join (",",keys (%{$buckets[$h][0]}) 
+) . "\n" ;
