尝试以O(nlogk) 时间复杂度和O(n) 空间复杂度解决。 【说明】最近尝试看了一些java,感觉的确要比C++简单不少,也尝试着使用一些java集合做些题目,这道题本身并不难,以下是java代码: classSolution {publicList<String> topKFrequent(String[] words,intk) { List<String> res =newArrayList<>(); Map<String,...
Explanation: "the", "is", "sunny" and "day" are the four most frequent words, 经典办法是使用哈希与数组原生的sort方法,sort里面先比较频率,然后再用字符串的localeCompare比较字符。 var topKFrequent = function(words, k) { var hash = {}; for (var i = 0; i < words.length; i++) { ...
