Re: finding number of contiguous letters

[Marknel]

The while loop worked fine with substring.

$in_string = "supercalifragic"

$str_length = length($in_string);

$stop_loop_num = $str_length - 2;

$temp_counter = 0;

while ( $temp_counter < $stop_loop_num ) {
    $three_chars = substr($in_string);
    push @str_elements, $three_chars;
    $temp_counter++;
}

While it's functional, I'm certain there is a better way and I'm always striving to learn!

no need for such a complex route when using substr; map is your friend:

my @parts = map { substr $str, $_, 3 } 0..length($str)-3;
