Re: Sorting a text file

[jonadab]

If you want to play amusing games with this problem, you could implement a crude Radix Sort:

require v5.8.0;
open INPUT, '<', '/path/to/the/file/where/the/data/are.stored';
my @line = <INPUT>; close INPUT;
for (reverse 8..13) {
   @line = sort {substr($a,$_,1) <=> substr($b,$_,1)} @line;
}
print @line;
