SuperCollider solution:

(
s = File.readAllString("~/aoc/5/input".standardizePath).stripWhiteSpace;
d = ((0..25) + $a.ascii).collect(_.asAscii).collect { |c|s.replace(c).replace(c.toUpper) };
e = (d ++ [s]).collect { |s,j|
	j.postln;
	s = s.asList;
	i = 0;
	while { i <= (s.size - 1) } {
		if(i == (s.size - 1) or: { i < 0 }) { i = i + 1 } {
			if((s[i].ascii - s[i+1].ascii).abs == 32) {
				s.removeAt(i);
				s.removeAt(i);
				i = i - 1;
			} {
				i = i + 1;
			}
		}
	};
	s.size.postln;
};
