Given an array consisting of n integers, find the contiguous subarray whose length is greater than or equal to k that has the maximum average value. And you need to output the maximum average value. Example 1: Input: [1,12,-5,-6,50,3], k = 4 Output:…

leetcode644. Maximum Average Subarray II 题意: 给定由n个整数组成的数组,找到长度大于或等于k的连续子阵列,其具有最大平均值.您需要输出最大平均值. 思路: 先计算前k个的avg和sum,然后每次往后加一个数,每次加一个数的同时用一个tempsum( = sum)依次减少前置的数,以此来模拟区间向后移动的计算.与直接的暴力相比,少了向后加又前减的一些步骤,减少了许多重复计算,但是这应该不是最优的算法,更快的算法暂时还没想到. ac代码: C++ clas…
