Not very beautiful, but it works.
java code:

Code: Select all

public void lowerCase(){
		String s = "mQmPtphqGrboHhmgaqVhCdwTwignlQvjIopDqVpgaNrwkAzVcnkHyNiPdSmgJmgrPiMjpnjdbuPucHnouwfKuPcybromnmbvfxJqRnnOvWsceZeYzRyqnkaaFsffjenxoIhqHnIzorlOdwZoxYmAuNwNnRppguwidvbtOqdbUngpZdbGqwYjfpLzPjRtwVwEqBbYmCqbKwuziCoEwPsIkJgruTbhdyWpvPztAodufjZxLaZcUeFaklSmeRfolohVbXoDfIqMqgIrQhzedqZlFwaBndQkQexBdLsCfXebrEfiOnSgYquyaqohxoDmLdDhwoOpgtkuRzeYziuvnuvnUuOtqasZueYpKfAkmKcJcWeocQvJguVsZfVovgrztAiryZivHqyMjoLyJdklKifmoWeOjVnogiiaBzDfrsWlOeAzPxltamqQiujZrpZrUcIlyktdJbhmNpDbltOlLnAqVhcxgObghpdcScgIiayqygUgwatiEzgzTsZgApUbbPynLfbzehzWsxcPbdcdfMucsCzjkWvjhMkiWuHfquqrcKwedqghiyHyMkSayRegeJcGw";

		System.out.println(r);
		System.out.println(r.length());
	}

i too solved it via the regexp

solved in java

Python's pretty concise again:

Code: Select all

print len(filter(str.islower, "..."))

or more modern:

Code: Select all

print sum([c.islower() for c in "..."])

(I didn't realise you could sum collections of bools. 'len' with a conditional list comprehension (replacing the 'filter' earlier) is more obvious to write, but I think this is easier to read.)

I used a Perl one liner to solve it:

Code: Select all

perl -le '$_="...";print tr/a-z//'

Posted: **Thu Jun 18, 2009 11:13 pm**

text editor + regex

Ok so it's a while since I solved it but heres my php code anyway:

Code: Select all

$unsortedlen = strlen($unsorted);
$counter = 0;

for($x = 0; $x < $unsortedlen; $x++)
{
   if (ord($unsorted{$x}) > 96) 
  {
    $counter++;
  }
}

echo $counter;
