【leetcode】1636. Sort Array by Increasing Frequency 题目如下: Given an array of integersnums, sort the array in increasing order based on the frequency of the values. If multiple values have the same frequency, sort them in decreasing order. Return thesorted array. Example 1: Input: nums =...
1636. Sort Array by Increasing Frequency 解题方法 先用collections.Counter计算频数存入字典,然后用sorted方法对字典中的键根据值顺序排序,第二关键字设置为键的倒序,返回一个元组组成的列表temp,其中每个元组的第一位是成员值,第二位是成员出现的次数,从头至尾遍历temp写元素即可。 时间复杂度:O(nlogn) 空间复杂...

Array.sort 如何根据字符串长度排序? 这里的知识点包括: Array,sort() 函数。其第一个参数是要排序的数组,第二个参数是比较方法。 lambda 表达式。其形式为 (参数) -> 逻辑表达式。 Integer.compare() 函数。 String 类的长度是用的 String,length() 方法。...sort...
Given a string, sort it in decreasing(降序) order based on the frequency(频率) of characters. Example 1: Input: "tree" Output: "eert" Explanation: 'e' appears twice while 'r' and 't' both appear once. So 'e' must appear before both 'r' and 't'. Therefore "eetr" is also a ...
