class Solution { public List<String> stringMatching(String[] words) { List<String> res = new ArrayList<>(); Set<String> set = new HashSet<>(); if(words == null || words.length == 0) return res; for(int i = 0; i < words.length; i++) { for(int j = 0; j < words.length; j++) { if(i != j && words[i].contains(words[j])){ set.add(words[j]); } } } res.addAll(set); return res; } } |
