problem 594. Longest Harmonious Subsequence 最长和谐子序列 题意: 可以对数组进行排序,那么实际上只要找出来相差为1的两个数的总共出现个数就是一个和谐子序列的长度了. solution1: 使用hashmap 用 HashMap 来做,先遍历一遍,建立每个数字跟其出现次数之间的映射,然后再遍历每个数字的时候,只需在 HashMap 中查找该数字加1是否存在,存在就更新结果 res. class Solution { public: int findLH…

Question 594. Longest Harmonious Subsequence Solution 题目大意:找一个最长子序列,要求子序列中最大值和最小值的差是1. 思路:构造一个map,保存每个元素出现的个数,再遍历这个map,算出每个元素与其邻元素出现的次数和,并找到最大的那个数 Java实现: public int findLHS(int[] nums) { if (nums == null || nums.length == 0) return 0; Map<Integer, I…

We define a harmonious array is an array where the difference between its maximum value and its minimum value is exactly 1. Now, given an integer array, you need to find the length of its longest harmonious subsequence among all its possible subseque…
