You are given a 0-indexed 2D integer array of events where events[i] = [startTimei, endTimei, valuei]. The ith event starts at startTimei and ends at endTimei, and if you attend this event, you will receive a value of valuei. You can choose at most two non…

给你一个整数 n ，共有编号从 0 到 n - 1 的 n 个会议室。 给你一个二维整数数组 meetings ，其中 meetings[i] = [starti, endi] 表示一场会议将会在 半闭 时间区间 [starti, endi) 举办。所有 starti 的值 互不相同 。 会议将会按以下方式分配给会议室：

You are given an integer n. There are n rooms numbered from 0 to n - 1. You are given a 2D integer array meetings where meetings[i] = [starti, endi] means that a meeting will be held during the half-closed time interval [starti, endi). All the values of starti…

给你一个包含 n 个节点的有向带权图，节点编号从 0 到 n - 1。同时给你一个数组 edges，其中 edges[i] = [ui, vi, wi] 表示一条从节点 ui 到节点 vi 的有向边，其成本为 wi。

You are given a directed, weighted graph with n nodes labeled from 0 to n - 1, and an array edges where edges[i] = [ui, vi, wi] represents a directed edge from node ui to node vi with cost wi. Each node ui has a switch that can be used at most once: when…

给你一个下标从 0 开始长度为 n 的整数数组 nums 和两个 正 整数 k 和 dist 。 一个数组的 代价 是数组中的 第一个 元素。比方说，[1,2,3] 的代价为 1 ，[3,4,1] 的代价为 3 。 你需要将 nums 分割成 k 个 连续且互不相交 的子数组，满足 第二 个子数组与第 k 个子数组中第一个元素的下标距离 不超过 dist 。换句话说，如果你将 nums 分割成子数组 nums[0..(i1 - 1)], nums[i1..(i2 - 1)], ..., nums[ik-1..(n…
