Write a script to display mirror image of a entered value and also check whether Palindrome?

print("Enter the no. to check for Palindrome : ");
$no = <STDIN>;
chop($no);

$i = 0;

# Store into a array
while($no != 0)
{
@array[$i] = $no % 10;
$no = int($no / 10);
$i++;
}

$i--;
$j=0;
$flag = "true";

# Check for Palindrome
while( ($flag eq "true" )&& ( $j < @array/2) ){
if (@array[$j] != @array[$i])
{
$flag = "false"
}
$i--;
$j++;
}

# Print the result
if( $flag eq "true")
{
print("It is a Palindrome\n");
}
else
{
print("It is NOT a Palindrome\n");
}
