better view for comparing right with wrong answers

[sneakyx]

At the moment, the users have to look very carefully, what was wrong in their answer.
It the direct comparision is shown, it would be better.
possible Vercomparisionsions
a) show both together, but aligned
b) show a comparision with composer require codedungeon/phpunit-result-printer

use Codedungeon\PHPCliColors\Color;
use Codedungeon\PHPCliColors\Color256;

public function highlightStringDifferences($string1, $string2) {
    // Vergleich der beiden Zeichenketten und Hervorheben der Unterschiede
    $diff = new \Diff\Diff($string1, $string2);
    
    // Erzeuge HTML-Ausgabe der Unterschiede
    $renderer = new \Diff\Renderer\Html\SideBySide;
    $diffOutput = $diff->render($renderer);
    
    return $diffOutput;
}

public function compareStrings() {
    $string1 = "Hello World!";
    $string2 = "Hello PHP!";
    
    // Hervorhebung der Unterschiede
    $highlightedDiff = $this->highlightStringDifferences($string1, $string2);
    
    // Rückgabe der hervorgehobenen Unterschiede an die Ansicht oder wo immer benötigt
    return view('diff_view', compact('highlightedDiff'));
