The following ranges are covered:

  1. 46 - 196
  2. 403 - 553
  3. 800-950
  4. 832-982
  5. 1008-1158
  6. 1407-1524

There is an overlap between two of the ranges. Your question is how much of the range between 1 and 1524 is covered. Do I have that correct?

Update: solution

use strict;
use warnings;

my (%covered);
open my $m, '<', 'count_try.txt' or die 'Cannot open count_try.txt';
while (my $seq = <$m>) {
    chomp $seq;

    my ($start, $range) = split /\t/, $seq;
    my ($fm,$to) = split /\.\./,$range;
    my $end = $start + 149;
    $end = $to if $end > $to;
    for(my $i=$start;$i<=$end;$i++) {
        $covered{$range}{$i} = 1
    }
}
for my $range (keys %covered) {
    printf "Coverage in range %s is %d\n",$range,scalar keys %{$covere
+d{$range}}
}
close $m;
