给你一个字符串 s 和一个字符串数组 dictionary 作为字典,找出并返回字典中最长的字符串,该字符串可以通过删除 s 中的某些字符得到。
如果答案不止一个,返回长度最长且字典序最小的字符串。如果答案不存在,则返回空字符串。
示例 1:
输入:s = "abpcplea", dictionary = ["ale","apple","monkey","plea"] 输出:"apple" 示例 2:
输入:s = "abpcplea", dictionary = ["a","b","c"] 输出:"a"
提示:
1 <= s.length <= 1000 1 <= dictionary.length <= 1000 1 <= dictionary[i].length <= 1000 s 和 dictionary[i] 仅由小写英文字母组成
class Solution { public String findLongestWord(String s, List dictionary) {
}
}
