  • question on string modification with perlfabrizio May 1, 2012 at 5:54 AM

    Hi, here's my problem. Given the input string below: $Input_string="10, 20, 25, 40-45, 50"; I want to get the output following output string: $output_string = "10 20 25 40 41 42 43 44 45 50": I need to do this in Perl language. I tried multiple things, like going through an array and such but that still does not work. For example: $_="10, 20, 40-45, 50"; s/,//g; #the 'g' says to substitute all occurrences s/-/../g; print "$_\n"; @array1 = (split / /, $_); foreach $elm (@array1) { print "$elm\n"; } This gives me the following output: 10 20 40..45 50 10 20 40..45 50 but that's not what I wanted..... thanks
