给定 n 个整数,找出平均数最大且长度为 k 的连续子数组,并输出该最大平均数. 示例 1: 输入: [1,12,-5,-6,50,3], k = 4 输出: 12.75 解释: 最大平均数 (12-5-6+50)/4 = 51/4 = 12.75 注意: 1 <= k <= n <= 30,000. 所给数据范围 [-10,000,10,000]. class Solution { public: double findMaxAverage(vector<int>&…

这是悦乐书的第278次更新,第294篇原创 01 看题和准备 今天介绍的是LeetCode算法题中Easy级别的第146题(顺位题号是643).给定由n个整数组成的数组,找到具有最大平均值的长度为k的连续子数组,并输出最大平均值.例如: 输入:[1,12,-5,-6,50,3],k = 4 输出:12.75 说明:最大平均值为(12-5-6 + 50)/ 4 = 51/4 = 12.75 注意: 1 <= k <= n <= 30,000. 给定数组的元素将在[-10,000,10,00…

Find the contiguous subarray within an array (containing at least one number) which has the largest product. For example, given the array [2,3,-2,4],the contiguous subarray [2,3] has the largest product = 6. 很显然是一个动态规划的问题,找到递归表达式就可以了,考虑到会有负负相乘的问题,所以应…
