Problem Description Given a circle sequence A[1],A[2],A[3]......A[n]. Circle sequence means the left neighbour of A[1] is A[n] , and the right neighbour of A[n] is A[1]. Now your job is to calculate the max sum of a Max-K-sub-sequence. Max-K-sub-sequ…

//hdu3415 Max Sum of Max-K-sub-sequence //单调队列 //首先想到了预处理出前缀和利用s[i] - s[j]表示(j,i]段的和 //之后的问题就转换成了求一个最小的s[j]了,这样就能够单调队列 //求最小值. //队列中维护的是区间的開始的位置j.我们插入队列中的是j-1,由于 //这个时候s[i] - s[j-1]刚好就是[j,i]段闭区间的和 //这里用两种方式实现,一种是stl,一种是手动模拟,两者的速度,測试的 //结果在杭电測试都是一样的,4…

Given a non-empty 2D matrix matrix and an integer k, find the max sum of a rectangle in the matrix such that its sum is no larger than k. Example: Given matrix = [ [1, 0, 1], [0, -2, 3] ] k = 2 The answer is 2. Because the sum of rectangle [[0, 1], […

题目描述: Given a non-empty 2D matrix matrix and an integer k, find the max sum of a rectangle in the matrix such that its sum is no larger than k. 解题思路: 根据题意,寻找二维数组中所有可以组成的矩形中面积不超过k的最大值,所以必须要求出可能组成的矩形的面积并与k比较求出最终结果.这里为了最终不超时,可以在一下方面进行优化: 1.设置一个数组比较当前列(或…
