When I'm counting numbers I don't store them all in memory and then
make a grand total -- I keep a running total and whenever I encounter
a number I add it to the running total and then promptly forget it
(the number, not the running total).

That should fix the issue of having an array of lines.

Use split to extract the numbers on each line.

man perlre ; perldoc -f split
