hi
if i have a book which contains 10 chapters and my purpose is to give every sentence in the book a number from 1 to 370 which is the total number of sentences
suppose the number of sentences for every chapter like this:
15, 24, 23, 110, 30, 58, 3, 22, 79, 6
the accumulating number of sentences is
15 39 62 172 202 260 263 285 364 370
the purpose of the program is to tell for example if i want sentence number 250 then it is in chapter 6 , i have the following solution, are there other solutions please!.
use warnings;
use strict;
my $counter=0;
my $tot=0;
my $wantedSentence;
my $item;
my @b=(0,0,0,0,0,0,0,0,0,0);
my @a=(15,24,23,110,30,58,3,22,79,6);
foreach my $numOfSentences (@a) {
     $tot=$tot + $numOfSentences;
     #accumulating totals to @b;
     $b[$counter]=$tot;
      $counter++;
}
print "@b\n";
$counter=0;
$wantedSentence = 250;
foreach  $item (@b) {
     if($wantedSentence <= $b[$counter])
        {$counter++;print "this sentence in chapter $counter";last;}

     $counter++;
}
