Ola,

I have the following data 
From DB
AB1/1
AB1/5
AB2/5

From Input
AB1/1
AB1/2
AB1/5
AB1/6
AB1/9
AB2/2
AB2/5
AB2/6
AB2/9
AB2/13

What I need to do is search the DB array for matching values from the Input array. So to produce an output similar to this: 
AB1/1 : Found AB1/1
AB1/2 : NotFound AB1/2
AB1/5 : Found AB1/5
AB1/6 : NotFound AB1/6
AB1/9 : NotFound AB1/9
AB2/2 : NotFound AB2/2
AB2/5 : Found Ab2/5
AB2/6 : NotFound Ab2/6
AB2/9 : NotFound AB2/9
AB2/13 : NotFound AB2/13

So I wrote this simple script: 
#! c:/perl/bin/perl.exe
#
use strict;
use warnings 'all';

my @NotFound;
my @DB = qw(AB1/1 AB1/5 AB2/5);
print "\nFrom DB\n";
for my $DBData (@DB)
{
   print "$DBData\n";
}
print "\nFrom Input\n";
my @Input = qw(AB1/1 AB1/2 AB1/5 AB1/6 AB1/9 AB2/2 AB2/5 AB2/6 AB2/9 A
+B2/13);
for my $InputData (@Input)
{
   print "$InputData\n";
}
##################################################
print "\nSearching\n";
for my $DBData (@DB)
{
   for my $InputData (@Input)
   {
      if ("$DBData" eq "$InputData")
      {
         print "$InputData : Found $DBData\n";
         last;
      }
      else
      {
         print "$InputData : NotFound $DBData\n";
      }
   }
}         

print "\nSize of NotFound Array $#NotFound\n";

Which produced this incorrect output! 
From DB
AB1/1
AB1/5
AB2/5

From Input
AB1/1
AB1/2
AB1/5
AB1/6
AB1/9
AB2/2
AB2/5
AB2/6
AB2/9
AB2/13

Searching
AB1/1 : Found AB1/1
AB1/1 : NotFound AB1/5
AB1/2 : NotFound AB1/5
AB1/5 : Found AB1/5
AB1/1 : NotFound AB2/5
AB1/2 : NotFound AB2/5
AB1/5 : NotFound AB2/5
AB1/6 : NotFound AB2/5
AB1/9 : NotFound AB2/5
AB2/2 : NotFound AB2/5
AB2/5 : Found AB2/5

Size of NotFound Array -1

I have spent sometime thinking about a solution for it, but the best I can produce is the above output.

Since coding problems like these are an absolute doddle for you guys, I wonder if someone can help me and show me how can I produce the required results efficiently and with minimal code?

Thanks for your help
