[JavaScript]Leetcode每日一题-矩形区域不超过K的最大值和 [题目描述] 给你一个 m x n 的矩阵 matrix 和一个整数 k ,找出并返回矩阵内部矩形区域的不超过 k 的最大数值和. 题目数据保证总会存在一个数值和不超过 k 的矩形区域. 示例1: 输入:matrix = [[1,0,1],[0,-2,3]], k = 2 输出:2 解释:蓝色边框圈出来的矩形区域 [[0, 1], [-2, 3]] 的数值和是 2,且 2 是不超过 k 的最大数字(k = 2). 示例
★实验任务 小 F 很爱打怪,今天因为系统 bug,他提前得知了 n 只怪的出现顺序以及击 倒每只怪得到的成就值 ai.设第一只怪出现的时间为第 1 秒,这个游戏每过 1 秒 钟出现一只新怪且没被击倒的旧怪消失.小 F 决定发动一次技能,他的技能最多 维持 k 秒,他希望获得最大的成就值,请你帮他计算他发动技能的时间 l 和技能 结束时间 r(r-l+1<=k).当存在多种方案使得成就值最大时,选择技能发动时间 l 最小的方案,再选择技能持续时间 r-l+1 最小的方案. ★数据输入 输入第一行
题目描述: 这是一道数据结构题. 我们拥有一个长度为n的数组a[i]. 我们有m次操作.操作有两种类型: 0 i val:表示我们要把a[i]修改为val; 1 l r k:表示我们要求出区间[l,r]的最多k个不相交子区间,并使得各个子区间的数的和尽量大,需要注意的是,我们也可以不选择区间,这时候数的和为0. N,m不超过10^5. 所有的ai和val的绝对值均不超过500.k不超过20.询问的数目不超过10000. 抛开k段先不管,假如要求连续一段的最大和,该怎么做? 对于线段树的一段[L,
