PERL : Sort substring occurrences in array of strings

Hi,

My developer is on vacation and I am not sure if there is something which is easier for this.

I have an array of strings. Each string in the array has "%" characters in it. I have to get the string(s) which have the least number of "%" in them.

I know how I can get occurrences :
Code:
 
my @str;
...array population here...
my $count = ($str =~ tr/"%"//);

But I am not sure what is the best way to get the string(s) with least number of "%"'s.

Any advise/help is highly appreciated.

Thanks.
sinpeak

mb_strtolower - Make a string lowercase

SYNOPSIS
string mb_strtolower (string $str, [string $encoding = mb_internal_encoding()]) DESCRIPTION
Returns $str with all alphabetic characters converted to lowercase. PARAMETERS
o $str - The string being lowercased. o $encoding -The $encoding parameter is the character encoding. If it is omitted, the internal character encoding value will be used. RETURN VALUES
$str with all alphabetic characters converted to lowercase. UNICODE
For more information about the Unicode properties, please see http://www.unicode.org/unicode/reports/tr21/. By contrast to strtolower(3), 'alphabetic' is determined by the Unicode character properties. Thus the behaviour of this function is not affected by locale settings and it can convert any characters that have 'alphabetic' property, such as A-umlaut (A). EXAMPLES
Example #1 mb_strtolower(3) example <?php $str = "Mary Had A Little Lamb and She LOVED It So"; $str = mb_strtolower($str); echo $str; // Prints mary had a little lamb and she loved it so ?> Example #2 mb_strtolower(3) example with non-Latin UTF-8 text <?php $str = "Txiotn a nE Baos unuvn yn, dpaokeCei unp vw0po kuvs"; $str = mb_strtolower($str, 'UTF-8'); echo $str; // Prints txiotn a nE Baos unuvn yn, dpaokeCei unp vw0po kuvs ?> SEE ALSO
mb_strtoupper(3), mb_convert_case(3), strtolower(3). PHP Documentation Group MB_STRTOLOWER(3)
