Codewars Solution Code Review

When you finished a task on Codewars: public class Printer { public static String printerError(String controlString) { int badCharCounter = 0; StringBuilder builder = new StringBuilder(); for (int i = 0; i < controlString.length(); i++) { if ((int) controlString.charAt(i) >= 110) { badCharCounter++; } } builder.append(badCharCounter).append("/").append(controlString.length()); return new String(builder); } } That's pretty nice, let's see how others did it: public class Printer { public static String printerError(String s) { return s.replaceAll("[a-m]", "").length() + "/" + s.length(); } }

A programming meme shows an elaborate Java solution to a Codewars task, followed by a much shorter one-line approach and a man staring blankly at the screen. The joke is about discovering that other programmers solved the same problem far more simply, prompting a stunned reaction.
