Don, your solution was 100% correct, as always!
As a note, within $(( )) and (( )) evaluation you do not need further $ evaluations. So the following works as well
Code:
for (( i=0; i<n; i++ ))

Code:
for (( i=0; i<(n-1); i++ ))

Last but not least, in bash-4 you can use an associative array to automatically sort out duplicates:
Code:
#!/bin/bash
echo "This is a sample Prog to remove duplicate integer items from an array"
echo "How many numbers do you want to insert"
read n
declare -A hash
for (( i=0; i<n; i++ ))
do
        echo "Enter Number"
        read num
        # we address the array by $num, and do not need a value
        hash[$num]=""
done
echo "Insertion is done, Below are the elements of the array"
# dump the keys
printf "%s\n" "${!hash[@]}"
echo "now loop through the keys"
for i in "${!hash[@]}"
do
   echo "do something with $i"
done

test::inline::content::legacy

Test::Inline::Content::Legacy(3pm)			User Contributed Perl Documentation			Test::Inline::Content::Legacy(3pm)

NAME

       Test::Inline::Content::Legacy - Test::Inline 2 Content Handler for legacy functions

SYNOPSIS

       Custom script content generation using Test::Inline 2.000+ with a custom generator functions

	 my $header = "....";
	 my $function = sub {
	       my $Object = shift;
	       my $Script = shift;
	       return $header . $Script->merged_content;
	 };

	 my $Inline = Test::Inline->new(
	       ...
	       file_content => $function,
	       );

       Migrating this same code to Test::Inline 2.100+ ContentHandler objects

	 my $header = "....";
	 my $function = sub {
	       my $Object = shift;
	       my $Script = shift;
	       return $header . $Script->merged_content;
	 };

	 my $ContentHandler = Test::Inline::Content::Legacy->new( $function );

	 my $Inline = Test::Inline->new(
	       ...
	       ContentHandler => $ContentHandler,
	       );

DESCRIPTION

       This class exists to provide a migration path for anyone using the custom script generators in Test::Inline via the "file_content" param.

       The synopsis above pretty much says all you need to know.

METHODS

   new $CODE_ref
       The "new" constructor for "Test::Inline::Content::Legacy" takes a single parameter of a "CODE" reference, as you would have previously
       provided directly to "file_content".

       Returns a new "Test::Inline::Content::Legacy" object, or "undef" if not passed a "CODE" reference.

   coderef
       The "coderef" accessor returns the "CODE" reference for the object

   process $Inline $Script
       The "process" method works with the legacy function by passing the Test::Inline and Test::Inline::Script arguments straight through to the
       legacy function, and returning it's result as the return value.
