ChallengeIt"s easy to solve it in two passes, can you do it in one pass?
Solutionclass Solution {
ArrayList longestWords(String[] dictionary) {
// write your code here
ArrayList res = new ArrayList();
for (String word: dictionary) {
if (res.isEmpty() || res.get(0).length() < word.length()) {
res.clear();
res.add(word);
}
else if (res.get(0).length() == word.length()) res.add(word);
else continue;
}
return res;
}
}
