Sum is 11

---

Solution:

my $tmp = 0;
my $sum = 0;
my $len = @ARGV;              
while($tmp < $len)
 {          
 $sum = $sum+$ARGV[$tmp];  
 ++$tmp;                    
 }
print "Sum is $sum";

Tips:

• @ARGV stores all command like arguments in array ie for input 5 6 , $ARGV[0] = 5 and $ARGV[1] = 6.
