Given an array with positive and negative numbers, find the maximum average subarray which length should be greater or equal to given length k. Example Given nums = [1, 12, -5, -6, 50, 3], k = 3 Return 15.667 // (-6 + 50 + 3) / 3 = 15.667 利用队列建立窗口 pu…

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…
