class Solution {
    public List<String> splitWordsBySeparator(List<String> words, char separator) {
        List<String> result = new ArrayList<>();

        for (String word : words) {
            StringBuilder stringBuilder = new StringBuilder();
            
            for (char ch : word.toCharArray()) {
                if (ch != separator) {
                    stringBuilder.append(ch);
                } else {
                    String str = stringBuilder.toString();
                    if (!str.isEmpty()) {
                        result.add(str);
                        stringBuilder = new StringBuilder();
                    }
                }

            String str = stringBuilder.toString();
