1、
Given a dictionary, find all of the longest words in the dictionary.
Given
{
"dog",
"google",
"facebook",
"internationalization",
"blabla"
}
the longest words are(is) ["internationalization"].
2、
思路：
1、得到数组里面最长的字符串大小
2、判断相等的字符串大小，添加进去。
3、源码：
class Solution { /** * @param dictionary: an array of strings * @return: an arraylist of strings */ ArrayList<String> longestWords(String[] dictionary) { // write your code here int maxLen = 0; ArrayList<String> ans = new ArrayList<String>(); for (int i=0; i<dictionary.length; ++i) if (dictionary[i].length()>maxLen) maxLen = dictionary[i].length(); for (int i=0; i<dictionary.length; ++i) if (dictionary[i].length()==maxLen) ans.add(dictionary[i]); return ans; } };
