给定一个非空且只包含非负数的整数数组 nums, 数组的度的定义是指数组里任一元素出现频数的最大值. 你的任务是找到与 nums 拥有相同大小的度的最短连续子数组,返回其长度. 示例 1: 输入: [1, 2, 2, 3, 1] 输出: 2 解释: 输入数组的度是2,因为元素1和2的出现频数最大,均为2. 连续子数组里面拥有相同度的有如下所示: [1, 2, 2, 3, 1], [1, 2, 2, 3], [2, 2, 3, 1], [1, 2, 2], [2, 2, 3], [2, 2] 最短…

697. Degree of an Array - LeetCode Question 697. Degree of an Array - LeetCode Solution 理解两个概念: 数组的度:[1,2,2,3,1]这个数组,去重后的元素为[1,2,3],每个元素在原数组中重复的次数分别是221,数组的度就是元素最大重复次数,这个数组中元素最大重复次数就是2 连续子数组:和字符串中的了串概念类似,数组元素顺序保持不变,取其中一部分,该题就是求在度相同的情况下最小连续子数组的长度 思路:数…

problem 697. Degree of an Array 题意:首先是原数组的度,其次是和原数组具有相同的度的最短子数组.那么最短子数组就相当于子数组的首末数字都是统计度的数字. solution1: class Solution { public: int findShortestSubArray(vector<int>& nums) { ; unordered_map<int, int> m; unordered_map<int, pair<int,…
