Given a circular array C of integers represented by A, find the maximum possible sum of a non-empty subarray of C. Here, a circular array means the end of the array connects to the beginning of the array.  (Formally, C[i] = A[i]when 0 <= i < A.lengt…

题意 给定一个正整数数组和K,数有多少个连续子数组满足: 数组中所有的元素的积小于K. 思路 依旧是双指针的思路 我们首先固定右指针r. 现在子数组的最右边的元素是nums[r]. 我们让这个子数组尽可能的长,尽可能的往左边拓展,假设最左边的元素的前一个元素是l. 即子数组(l,r]. 显然对于以nums[r]结尾的满足题意的数组个数为r−lr-lr−l 对于 (l1,r1],&ThickSpace;(l2,r2](r1<r2)(l_1,r_1],\;(l_2,r_2] \quad (r_1…
