I have this question and below it is what I have now it does not seem to work. can we troubleshoot to gether?

Ask the user for a list of sequence lengths, separated by whitespace (Example: 100 123 45 …etc.). The sequence lengths will be stored in a string called $input. a. Split the String $input and create an array. b. Use the foreach loop to get the sum of all sequence lengths. c. Print the average. this is what I have now: but I don't get the space at the print command. 

use strict;

use warnings;

my $i = 0;

my $input = "";


while ($i < 3) {

  chomp(my $num = <>);

  $input .= $num . "". $num;

  $i++;

}

print "Total input is $input\n";

my @nums = split(' ', $input);

foreach (@nums) {

  my $sum += $_;

}

print my $sum / @nums . "\n";

exit;
