Python是一种广泛使用的编程语言，其collections模块中的Counter类提供了统计元素频次的功能。其中的most_common()方法能够返回一个列表，列出出现频率最高的n个元素及其对应次数，并按频率从高到低排序。本文将介绍如何在Python编程中实际运用Counter的most_common()方法 ...

Given a non-empty list of words, return the k most frequent elements. Your answer should be sorted by frequency from highest to lowest. If two words have the same ...

Given a non-empty array of integers, return the k most frequent elements. You may assume k is always valid, 1 ≤ k ≤ number of unique elements. Your algorithm's time complexity must be better than O(n ...
